LS-123 (5100)

LS-123 (5100) by MPI Chemie is a liquid non-basic HALS for coatings, printing and packaging. It improves the retention of mechanical properties. It is also used in architectural-, furniture- & flooring and industrial coatings. It has been developed especially for high performance and durability requirements for all exterior solvent-based, high solids, acid catalyzed automotive and industrial coatings, such as two-coat metallic thermosetting acrylate systems or one-coat opaque thermosetting acrylate and polyester coatings. Its low basicity prevents possible interactions with acidic paint ingredients such as catalysts. Its efficiency provides significant improvement in coatings performance by minimizing paint defects such as cracking and gloss reduction for clear coats as well as chalking for pigmented paints. It also enables easy emulsification into waterborne systems. In automotive coatings, combinations of this grade with the UV-928 or UV-1130 will significantly improve the weathering resistance and provide superior protection against color change, blistering, and de-lamination. 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 (5100) with UV-1130 have been found highly effective in air drying alkyd-based formulations.
