PRODUCT FEATURES AND APPLICATIONS
* LS 123 has been developed especially for high solids, acid catalyzed automotive and industrial coatings, i.e. two coat metallic thermosetting acrylate systems or one coat opaque thermosetting acrylate and polyester coatings.
* LS 123 is recommended for applications such as: automotive and industrial coatings· decorative paints and wood stains or varnishes.
Its high efficiency has been demonstrated in a variety of other binders and applications such as:
·alkyd/acrylic air drying automotive refinish paints
·alkyd oxidative drying paints and varnishes
·two pack non-isocyanate coating technologies
*The liquid form of  LS 123 also enables easy emulsification into water-borne systems.
*The performance of  LS 123 can be significantly improved when used in combination with a UV absorber.
In Automotive coatings, combinations of  LS 123 with the UV absorbers 1130,  UV 928, or  UV 400 will significantly improve the weathering resistance and provide superior protection against gloss reduction, cracking, color change, blistering and delamination.
The light stabilizers may be added in two coat applications to both the base and the clear coat. In Wood Coatings, combinations of  LS 123 with the UV absorbers.  UV 384 or  UV 1130 have been found highly effective in air drying alkyd based formulations.
The light stabilizer blends can be added to film forming finishes as well as decorative penetrating stains. The amount of  LS 123 required for optimum performance should be determined in trials covering a concentration range.
