Chemark UV-389 is a liquid UV absorber designed specifically for the protection of polymers from the damage of UV light. Chemark UV-389 is more solvent soluble, has better resin compatibility, is less volatile, and provides a degree of stabilization that is significant better than other UV absorber based on benzotriazole or benzophenone which are commercially available in the market

Chemark UV-5411 is a high molecular weight ultraviolet light absorber of the hydroxy phenyl benzotriazole class. Its inherent off-white color renders itself more suitable for application where light color is critical. Its low volatility and high lipophilicity makes it especially useful where additive losses may occur during high temperature process.

Chemark AO-1076 is a steric hindered phenolic antioxidant for protecting a series of organic and polymeric substrates like plastics, synthetic fibers, elastomers, adhesives, oils and waxes. Because of its specific chemical structure and low volatility, Chemark AO-1076 exhibits very high performances including anti-oxidative effect, long term thermal stability, non-discoloring property, extraction resistance and good compatibility with most substrates.

Chemark 1289DW is developed specifically for waterborne UV curing system with the below three advantages, i) Chemark 1289DW has favorable stability and compatibility with aqueous solution system. ii) A small amount of Chemark 1289DW can have excellent curing effect on white and colored screen printing inks and coating systems,and have excellent anti-yellowing properties. iii) Chemark 1289 can be applied to thick coating systems and daylight curing system.
