Uv Absorber Uv2908

Supplier: Uv absorber, light stabilizer, anti oxidant and additive masterbatch

UV-5151 is a liquid blend of a hydrophilic 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a basic hindered amine light stabilizer(HALS).It has been designed to fulfil high cost/performance and durability requirements of exterior waterborne and solvent borne industrial and decorative coatings. The broad UV absorbance of the used UVA makes it suitable for a wide range of coatings for wood, plastics and metal. The synergistic combination imparts superior coating protection against gloss reduction, cracking, blistering, delamination and color change and provides full substrate protection. Appearance : Viscous amber liquid. Active ingredient, %: 93min. Viscosity at 25 degree: 7000mPa.s max. Density at 20 degree: 1.10 g/cm3 Ash, %: 0.1max. Transmittance: 460nm 95%min. 500nm 97%min. UV-5151 is a universal light stabilizer which can be used in a variety of solvent borne and waterborne industrial and decorative coating systems

UV-5050 is a liquid light stabilizer blend developed specifically for coatings. Its high thermal stability and permanence makes it suitable for coatings exposed to high bake temperatures and/or to extreme environmental conditions. It has been designed to fulfill the high cost/performance and durability requirements of trade sales and industrial coating applications. Its broad UV absorbance allows effective protection of light sensitive substrates such as wood and plastics. Appearance : Viscous amber liquid Viscosity at 25 degree: 10000mPa.s Density at 20 degree: 1.03 g/cm3 Miscibility: UV-5050 is miscible to more than 50% with most commonly used paint solvents.Water solubility is less than 0.01%. UV-5050 is a versatile light stabilizer which can be used in a wide variety of clear and pigmented coating systems, based on water-borne or solvent-borne paint technology. Its use is especially recommended for clear and light pigmented coatings in applications

Chemical name: N,N-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N diformylhexamethylenediamine CAS No 124172-53-8 Molecular formula: C26H50N4O2 Molecular weight: 450 Molecular structure Specification Appearance: White to off white crystalline powder Purity, %: 99 min. Loss on drying,%: 0.5 max. Melting point: 155-158 degree Application LIGHT STABILIZER LS-4050 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. It is suitable for the stabilization of polyolefins, particularly in thick-walled PP molding and PP fibers, as well as ABS, PS, PA and polyesters.It is highly compatible with pigments.
