Light stabilizer
Commodity name	VIOCHEM LS-292　　　Details
Commodity name	VIOCHEM LS- 770　　 Details
Commodity name	VIOCHEM LS- 765　　 Details

Chemical Name	LS-292
Structure	and
Applications	LS-292 is a highly effective liquid stabilizer used for a wide range of polymers and applications including polyurethanes, sealants, adhesives, elastomers, unsaturated polyesters, acrylics, vinyl, polymers (PVB, PVC), styrene homo- and copolymers, polyolefins, liquid color concentrates, and other organic substrates.
Guidelines for use	Use levels for LS-292 range between 0.1%, depending on the substrate and performance requirements. Synergistic may be obtained when LS-765 is used with a ultraviolet light absorber. Performance data are available in many substrates. For optimum effectiveness, adequate base stabilization (e.g. antioxidants/ processing stabilizers) of the polymer is necessary to prevent thermal oxidation. Sulfur containing stabilizers such as thioesters have e sometimes been found to have a negative effect on the performance of LS-292. Such influences should be evaluated in specific customer testing. LS-292 may crystallize during storage below 0℃, however the product can be easily liquefied by slight warming.
Handling & Safety	In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Protect skin. Avoid contact with eyes. Avoid release to the environment. For more detailed information please refer to the material safety data sheet.

Chemical Name	Bis (2,2,6,6,-tetramethyl-4-piperidyl) sebaceate
Structure
Applications	LS-770 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and Polyacetals.
Guidelines for use	The recommended concentrations range between 0.1% an 0.5%, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of LS-770 in various substrates and for various applications is available upon request.
Handling & Safety	In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation. Avoid contact with eyes. Avoid release to the environment. Avoid dust information and ignition sources. For more detailed information please refer to the material safety data sheet.
