Solvent -based coatings emit volatile organic compounds (VOCs) into the air during processing, drying and curing, such as aromatics, esters or ketones. In addition, such volatile substances will further produce O3 under the action of sunlight, which poses serious harm to human health and the environment.
With the improvement of environmental protection legislation all over the world, water-based coatings have attracted people's attention because of its Eco-friendly and excellent performance. Among them, water-based acrylate coating is widely used in home decoration coating, car repair coating, exterior protective coating and other fields.
Water-based acrylic coating is made of acrylic or methacrylate polymer, in addition to the formula usually contains emulsifiers, stabilizers, antioxidants, pH regulators and other additives.
Advantages of water-based acrylate coating：
1 It’s Eco-friendly with low VOC, low toxicity and reduction of irritation.
2 Excellent color retention. It has well luster and transparency.
3 Good adhesion when primer selected properly.
Applications:
1. Interior and exterior wall decoration in construction industry.Acrylic coating is easy to apply and environmentally friendly, becoming the leading variety of interior and exterior walls.
2. With the development of the plastic industry, the increasing number of plastic products, acrylic coating can improve the surface decoration and protection of plastic objects.
3. Acrylic paint is also widely used in automotive varnish and repair paint.In high-grade automotive coatings, higher requirements are put forward for decoration, weather resistance and adhesion of acrylic coatings.
However, after photocuring, there will be some photoinitiator and free radical residue in water-based acrylic system. Under UV irradiation these further migrate to its surface, then trigger chain reaction. The performance of coating will be reduced, such as yellowing, blistering, cracking, etc.
Following OMNISTAB additives help alleviate these problems and could extend the service life of Acrylate coating!
OMNISTAB UV1130 is easy to be emulsified, better dispersion could be obtained by dissolving in water-soluble solvent such as diethylene glycol diethyl ether, so it is especially suitable for water-based system.
When OMNISTAB UV1130 & OMNISTAB LS292 are used together in water-based system, synergistic effect will be achieved. This could produce better performance, like weather-resistance.
OMNISTAB UV5151 is a customized “additive package” of OMNISTAB UV1130&LS292 with a 2:1 ratio. This serves better Processing convenience for customer.
