ACURE™ – Game Changing New Resin Chemistry for Coatings

ACURE™ is a new, non-isocyanate resin chemistry for coatings based on Michael Addition. Historically the Michael Addition has been too fast and difficult to control for practical use on coatings. Allnex has developed and patented new technology which harnesses ACURE™ ’s speed via use of a unique C0₂ blocked catalyst and kinetic control additives which give the paint formulator the tools needed to manage ACURE™ ’s use across a number of different applications and application conditions. This proprietary technology gives ACURE™ it’s ACURE™ – What’s “Under the Hood”?

In ACURE™ systems, allnex typically uses a relatively low molecular weight malonated polyester with a relatively low molecular weight acrylate like diTMPTA as its primary Michael Addition reactants. To enable Michael Addition, a strong base catalyst is needed. To enable Michael Addition’s extremely fast cure and create potlife, allnex blocked the catalyst with carbon dioxide. This approach preserves the inherently fast curing kinetics of Michael Addition while remarkably providing hours of potlife, orders of magnitude beyond those seen in typical 2k isocyanate or other chemistries.
ACURE™ chemistry is further enhanced by the use of kinetic additives which are used to slow the system further, providing the formulator with additional degree’s of control so as to manage coatings properties including open time, appearance in thick films and coating performance in varying environmental conditions.
Alternatives to Polyurethane systems don’t come easily. ACURE™ provides coatings properties never before seen in the Coatings Industry. If you’re looking for an Eco Friendly, Green Polyurethane coating system – ACURE™ has arrived.

Are you ready for EU Poison Centre Notification Format?

Consumers and workers come into daily contact with hazardous chemicals, and although they are expected to be used according to safe-use instructions, unintentional exposure may happen: ingestion, skin contact, inhalation, etc. In those cases, emergency professionals need rapid product identification, information about the chemicals contained and its hazardous properties, all these in order to facilitate the identification of the correct treatment and to avoid further damage.

And this is exactly what a poison centre does: it provides medical advice to citizens and healthcare professionals on health emergencies arising from exposure to hazardous chemicals or to other toxic agents; such as medicines, plants, bites and stings. Poison centres in the EU answer calls for support daily and around the clock.

On 22 March 2017, the Regulation (EU) nº 2017/542 was published, adding the Annex VIII, about the harmonised information relating to emergency health response. According to the ECHA, “It’s about harmonisation, and harmonisation brings synergies and efficiencies”. It was designed to regulate all hazardous mixture notifications (mixtures classified with health and/or physical hazards) within the EU, and established two new concepts related to chemical safety:

A harmonised information format file: a common format file which will gradually replace the current national requirements in force.
A Unique Formula Identifier (UFI): a unique code for each product which will be added on the label.

This new system, although efficient and beneficial in the long term, also implies a new complex notification process for companies, which will have to notify their products in the official language of each country in which they are marketed, pay different national taxes, etc. Providing harmonized information will certainty improve emergency health response, but the number of notifications is expected to significantly increase, and the producers and manufacturers who have started to work with the new system have already experience workability issues such us:

Insufficient time prior to deadline to assimilate notification tools.
Regular product variations that will lead to multiple and frequent changes of UFI for the same product.
Problems working with the ECHA Submission portal: navigation is complicated, too many clicks; it is not always directly clear if you made a wrong input, since validation is only available at the end of the process; notification via Guided Dossier Preparation took approx. 2 – 3 hours for a single product.

To overcome these inefficiencies and for the harmonized notification system to be truly useful for society, but also viable for companies, experts believe that there is a need for managed automation that minimizes the impact of:

Tens of thousands of products to be notified.
Frequent formulation changes. Partly own initiative, partly by raw material suppliers or driven by legislation changes.
Not feasible to do notifications & updates manually. Notifications must be generated in bulk.
Automation requires standardization. The solution must work for thousands of notifications at a time.

Time is running out, since the new harmonized notification process shall apply from 1 January 2021, after its publication in the Official Journal of the European Union. That is why we have updated CHEMETER, a reliable SDS authoring software which provides you with country specific legislation, up-to-date regulatory information, continuous new features development and professional assistance. It is also a friendly modular software which accommodates each company’s needs considering the country, sector and the aim of the company. It creates an extended range of documents; such as SDS, e-SDS, labels, dangerous goods documents and sector specific paperwork. It is one of the highest implemented software solutions worldwide, and now in addition, we have updated it to provide it with an additional module that issues automatic notifications in a few minutes.

The new module is specially designed to help users to comply with new poison Centre Notification Requirements for Hazardous Mixtures in the EU. It automatically creates PCN dossiers for harmonised notifications. Just in a few minutes, users will get the file with all the necessary documentation: automatic UFI code generation, toxicological information, complete chemical composition, etc. It is a simplified process, which indicates step by step in a simple way the data that the user needs to complete it. In a few clicks, users will get the file to notify all products. It is a significant time saver compared to the 2 or 3 hours it would take to generate the Poison Center Notification (PCN) format for a single product using the official portal.

KIMICELL HEC

Announcement

Tennants as distributor for Vink Chemicals are pleased to offer a new range of Kimicell thickeners.

Description

Available in a range of low, medium or high viscosities, the Kimicell Hydroxyethyl Cellulose is used as a thickener for water-based paints and coatings. They are also used as admixture performance enhancers.

They also offer bio-stable grades, offering better resistance than most other soluble gums and polymers and this resistance to enzymatic and chemical degradation elicits a more stable viscosity.

Function

It increases the paint/coating in can viscosity, sag resistance (especially in combination with HEUR) and enhancing coverage. It also provides good water-retention, rheology and colloid protection, especially when used in those solutions where a non-ionic material is desired. It reduces sedimentation of the pigments and fillers and can also contribute to the dispersion of pigments by improving the flow during grinding, helping to stabilize the pigment from flocculation. In admixtures they can also be used to improve the properties of mortars such as water-retention, workability & open time.

Application

Normal dosage is 0.4-0.8% w/w. Paint made from the lower molecular weight grades are more resistant to spatter during roller application for example.

Sail into a new dimension of Orange

Autumn is a time when reds, yellows and oranges take centre stage. The novel Pacific Orange L2828 pigment from BASF opens up the orange colour-space for paint formulators by providing a highly chromatic hybrid pigment chemistry designed to meet the demanding requirements of powder and industrial coatings, including for lead-chrome replacement.

In comparison to other pigments in the orange colour space if offers outstanding weather resistance and good opacity, with high temperature and chemical stability.
It can be combined with DPP Reds without colour shift, even at higher powder coating curing temperatures, in fact it is the ideal formulating partner to create super-durable orange RAL shades or corporate colours in combination with other high performance organic or inorganic pigments. Pacific Orange is also an excellent choice to overcome the fading of pale or pastel shades in architectural exterior applications due to its excellent weathering fastness in white reductions.

The new pigment will be showcased at Surfex in June 2021 but for further information or to sample please contact Chris Morgan, Head of Sales: Coatings, Inks & Plastics BTC UK Email: christopher.morgan@btc-europe.com

Siltech – Silicone Amines for Coatings

Silicone amine polymers are an interesting category of materials within silicone chemistry.
They tend to provide the very best handle and softness to textile substrates.
They are also quite hydrophobic, so are used in applications such as car care.
They can additionally be used as reactive components in resins.

Broadly speaking, there are 5 categories at Siltech, as follows:

1 – Aminoethyl aminopropyl-based, with structure as shown:

“a” and “b” can be varied. Silamine 2972 and Silamine MUE are good examples within this product group.

2 – Reactive amino-functional prepolymers, with structures as shown below:

There are a multitude of types, and these can be co-reacted into coatings and resins in order to provide flexibility and add impact resistance.

3 – Silicone polyether amines, as shown here:

In this case, the aminoethyl aminopropyl groups are “solubilised” with polyether groups. For example, Silamine D208 EDA is water-soluble. These types are also reactive (carbinol functional), and a, b, c, d and e can be varied.

4 – Silicone alkyl amines have alkyl groups in addition to the amine functionality, in order to improve organo-compatibility. Silamine T-97 is one example, and Siltech has made a series of these products.

5 – Fluorosilicone amines are niche, but Silmer NHF Di-H1 is one example, which has pendant fluoro groups and terminal allyl amines.

Siltech – Using SilmerTM Reactive Silicones to Modify Coatings

Silicon and Carbon are the in same column of the Periodic Table, and so the chemistries of Si and C are very closely related. Siltech builds upon this similarity in the “Silmer”^TM reactive line of products, in order to manufacture numerous functionalised pre-polymers. The resultant silicones can be co-reacted into analogous non-silicone systems in order to improve slip, flexibility, abrasion resistance, release, and hydrophobicity.

In the most general terms, the Silmer^TM reactive pre-polymers are either multi-functional or linear di-functional, and there is an ever-increasing list of functional types, including the following:

Hydroxyl (carbinol) OH
Tetra Hydroxyl (carbinol) OHT functional, for better network formation and improved organo-compatibility.
Acrylate ACR
Tetra Acrylate ACRT
Hydroxy OH ACR Acrylate functional.
Hydride H
Vinyl VIN
Isocyanate NCO
Amine NH
Epoxide functional, both glycidyl-based EP and cycloaliphatic-based EPC.
Trimethoxysilane TMS and Triethoxysilane TES
Thiol SH
Carboxy COOH

Please contact dave.wilson@siltech.com to discuss any of these products.

Trailblazers and innovators support the aqueous trend

The growing adoption of aqueous systems across the coatings industry is supported by additives which address key challenges. Here we highlight a selection of BYK’s wetting and dispersing additives for water-based systems, available across the UK and Ireland from Blagden.

Aqueous coatings now account for 60% of the coatings market and are on an above-average growth trajectory according to our key supply partner, BYK Chemie GmbH. Such systems have health and environmental benefits and are increasingly required to meet legislative requirements.

The challenges facing formulators in creating water-based coatings are steadily being overcome with innovative and effective additives. BYK has been at the forefront of such innovation, developing an extensive portfolio of products for aqueous systems.

The four wetting and dispersing additives highlighted here range from trailblazing originals to brand new products:

Trailblazer continues to set industry standard: At its launch in 1990, Disperbyk-190 was a trailblazer. Since then, its impressive product profile has seen it become an industry standard worldwide. Suitable for all pigments, its excellent wetting and dispersing quality produces high gloss and transparency levels as well as low viscosity. The effect is to improve flow behaviour and increase pigmentation.

First to offer VOC-free with electrosteric stabilisation: By combining these two features, Disperbyk-199 enables paints and pigment concentrates to meet legislative requirements as well as demand for greater efficiency. Ideal for inorganic and organic pigments, it is a cost-effective alternative to commonly-used dispersants and high molecular weight wetting and dispersing additives.

New versatile additive for the full spectrum of coatings: Versatility is a key attraction of Disperbyk-2014. It can be used in the full spectrum of coatings, from aqueous coatings and printing inks to UV, solvent-borne and solvent-free systems. It also has broad compatibility with a large variety of solvents and binders. Its highly deflocculating effect makes it possible to formulate coating systems with excellent optical properties such as improved colour strength, gloss and transparency and reduced haze.

Specialist product for high-quality, aqueous pigment concentrates: Another VOC-free wetting and dispersing additive, Disperbyk-2015 is based on controlled polymerisation technology enabling a defined molecular weight distribution for use in many different binder systems. It shows excellent compatibility in a range of water-borne resin systems. It enables high levels of gloss and exceptional colour strengths with optimum viscosity and good levelling properties.
