Introduction

Today, the coatings, paints, inks, adhesives and sealants markets increasingly require sustainable solutions such as waterborne, high-solids solvent-borne liquids, as well as low-VOCs systems. Sustainability in terms of low eco-toxicity, biodegradability and high content of renewable materials are driven by international norms and customer requests. Coatings need high weather and temperature resistance, scratch resistance, high-gloss, anti-stain, optimum adhesion and superior surface wetting, as well as enhanced durability. UniteChem stabilizers are optimized for such needs, improving also pigment dispersion and color yield development.

Recommendation

UniteChem LS 292 is the most versatile and efficient solution for UV stabilization of coatings, paints, inks, adhesives and sealants assuring durability and gloss retention. It is commonly combined with UniteChem UV 329 to ensure a high synergistic performance. Alkoxy N-OR HALS UniteChem LS 123 is recommended for acid catalyst-cured paint systems and for low interaction with flame retardants, for sulfur chemicals and catalyst residues. LS 119 is the state-of-the art solution in powder coatings. Special UniteChem formulations for low VOC emissions, optimized pigment dispersion and thermal resistance include LS 119, UV 234 as well as UniteChem’s unique LS 610 and LS 611 systems. Where temperature resistance is required, UniteChem AO 1076 is one of the best choices as a thermal stabilizer for coatings, paints, inks, adhesives and sealants. For paints that are cured at high temperatures a combination of AO 168 and AO 1076 or other blends is suggested.
