Chemical name: [3-[3-(2H-Benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-Hydroxyl phenyl]-1-oxopropyl]-hydroxypoly(oxo-1,2-ethanediyl) CAS No.:104810-47-1,104810-48-2, 25322-68-3 Appearance: Yellowish to light amber liquid Purity: 104810-47-1:36.0-38.0% 104810-48-2:50.0-52.0% 25322-68-3:12.00% Transmittance: 460nm 95.0%min 500nm 97.0%min UV 1130 is a type of benzotriazole UV absorber which is widely used in coatings. These combinations improve the durability of clear coats by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and delamination. The product is easy to emulsification, especially suitable for aqueous system. It is suitable for industrial and automotive coatings. Beside, its broad UV absorption allows efficient protection of light sensitive base coats or substrates such as wood and plastics.

It is of light color, non-toxicity, good Compatibility, small mobility and easy processing. It is widely applied to Pe, pvc, pp, ps, pc organic glass, pp fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability on drying phenol aldehyde, varnish of Alcohol, polyurethane, acrylate, etc. 20kg/pc

Bemotrizinol, also called Bis-ethylhexyloxyphenol Methoxyphenyl Triazine, which is a light yellow to yellow powder, a kind of ultra-fine organic particle technical chemical sunscreen agent, suitable for compounding solutions of high PA value sunscreen products. This chemical sunscreen has triple high-efficiency sunscreen effects, including absorption, scattering and reflection of UVA and UVB. It can fully cover the UVA band, has inherent light stability, and has good dispersion in water. When combined with other sunscreens, Bemotrizinol has an obvious synergistic effect, which can increase UVA protection, reduce skin irritation, and is suitable for use in high-PA value sunscreens.

JADEWIN UV 1789(AVOBENZONE) is broad spectrum UV absorber with effective absorbtion in both UVA and UVB region JADEWIN UV 1789(AVOBENZONE) is suggested to be used in sunscreen products and formulation of protective hair-care, medicated Skin-Care and also to quench phototoxic skin reactions initiated by weak phototoxic materials. JADEWIN UV 1789(AVOBENZONE) is incompatible with formaldehyde,formaldehyde donor preservatives and heavy metals Pink-Orange Color with Iron, formulation with PABA and its esters develop a yellow color. It can form complexes with aluminium above PH.7. So JADEWIN UV 1789(AVOBENZONE) should avoid Iron and Ferric Salts, Heavy metals,Formaldehyde donors, PABA and PABA esters.

JADEWIN UV 3035 is very effective at protecting plastics and coatings from the damaging ultraviolet radiation found in sunlight. JADEWIN UV 3035 offers excellent UV protection and good heat stability, a combination which makes it useful in many thermoplastic resins. It contributes less color to coatings and plastics than many other UV stabilizers. Dosage is 0.1~0.5% based on polymer weight.
