advantage and

application

uv-123 has low alkali property and widely used in acrylics, polyurethanes, sealants, adhesives, rubbers, impact modified polyolefine blends (tpe, tpo), vinyl polymers (pvc, pvb) polypropylene and unsaturated polyesters. moreover, potential interactions can occur with other components of either the formulation or the paint system. uv-123 is particularly recommended for coating application. it also provides outstanding stabilization performance, especially under critical conditions when in contact with aggressive media including acids, flame retardants, sulfur, and catalyst residues.
