Main uses and principal characteristics

 Chemark UV-292

 Bis(1,2,2,6,6-pentamethyl-4-piperidinyl)

Slight yellow viscous liquid

It is an effective light stabilizer

for polymers such as polypropylene, high density polyethylene, unsaturated

polyester, polymethylmethacrylate etc. It is particularly recommended for polyurethanes because of its good solubility      in organic solvents, such as polyols and dimethylformamide.

 Chemark UV-384

 Benzenepropanic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1- dimetylethyl)-4-hydroxy-, C7-C9 branched and linear alkylester

Yellow to light amber liquid

Chemark UV-384 belongs to the family of substituted benzotriazoles which protect against ultraviolet radiation. Chemark UV-384 is a liquid in nature and is highly miscible in most of monomers and oligomers which makes it particular useful for automobile and industrial coatings.

Chemark UV-900 (UV-Absorber)

2-[2-hydroxy-3,5-di-(1,1-dimethylbenzyl)]-2H-benzotriazole

Slightly yellowish crystalline powder

Chemark UV-900 is recommended for application such as: Automotive coatings, Coil coatings & Powder coatings. Concentration of 1-3%  of Chemark UV-900 is recommended.

Cemark  UV-5582

Benzenepropanic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimetylethyl)-4- Hydroxy-, C7-C9branched and linear alkyl ester

Light Yellow liquid

Chemark UV-5582 belongs to the family of substituted benzotriazoles which protect against ultraviolet radiation. Chemark UV-5582 is a liquid in nature and is highly miscible in most of monomers and oligomers which makes it particular useful for automobile and industrial coatings.

Chemark UV-770

Bis(2,2,6,6-tetramethyl-4- piperidyl)Sebacate

White, dust free and free-

lowing beads

As a highly efficient Hindered Amine Light Stabilizer for organic polymers.

Chemark UV-326

 2-(3'-t-butyl-2'-hydroxy-5'- methylphenyl)-5-chloro-benzotriazole

Light yellow crystalline powder

It is a highly efficient UV-absorber for polyolefins, polyesters, PVC and coatings. It has good activity in UV absorption and FDA approval in selected polymers. It has good compatibility in a variety of polymers and good thermal stability.

Chemark UV-327

2-(3',5'-di-t-butyl-2'-hydroxy

phenyl)-5-chlorobenzotriazole

Pale yellow crystalline powder

Its excellent stability to heat and light, low volatility, good color, superior wash fastness, and resistance to gas fading make it useful for stabilizing polyolefins, cold-cured polyesters, PU, dyes and pigments against ultraviolet radiation.

Chemark UV-389

Dialkyl aminobenzoic ester acrylic modified type UV absorber and Light stabilizer

Light yellow liquid

 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
