摘要

CASE 3232 "METHOD FOR STABILIZING LACQUERS AND COATINGS, AND THE STABILIZED COMPOSITIONS OBTAINED." Acrylic or alkyd resins and polyester based covering or coating compositions are stabilized against the action of light and moisture by adding, possibly in the presence of conventional stabilizers and antioxidants, at least one compound containing at least one N-substituted, sterically hindered piperidino, morpholino or pyrrolidino group, and at least one silyl function, or a polymer structure with a polyorganosiloxane structure containing sterically hindered piperidino groups in the molecule.
