Chiguard® GA403 (GA403) is a novel UV blocker derived from vanillin. Its high absorption in the UV-A wavelength region allows it suitable for optical applications requiring blue light absorbance.
Chiguard® R-455 is a novel reactable benzotriazole UV absorber. It carries two primary hydroxyl groups, which can react with hardeners and covalently bond with the polymer backbone.
Two new emulsified liquid UVAs, Chiguard® 5582WB, Chiguard® 5400WB and one waterborne HALS Chiguard® 101WB are introduced here. These three product feature improved resin compatibility and coatings storage stability across all waterborne systems.
Revonox® 608 is a spiro phosphite antioxidant, which is a family of compounds known for their high phosphorous content and superb antioxidant efficiency compared with other phosphite-based antioxidants.
Revonox® 420V is a phenol-free primary antioxidant derived from palm oil and resistant to gas-fading. It has excellent initial color and anti-yellowing properties.
