Acrylate-ester-siloxane-ester-acrylate paint
Abstract
Abstract A NOVEL SILOXANE-ESTER-ACRYLATE PAINT BINDER RESIN THAT IS CROSSLINKABLE WITH VINYL MONOMERS BY EXPOSURE TO AN ELECTRON BEAM IS PRODUCED IN A THREE STEP REACTION. THESE RESINS MAY BE PRODUCED BY THE PROCESS WHEREIN (1) A HYDROXY ACRYLATE SELECTED FROM C5-C12 MONOHYDROXY ACRYLATES WHICH ARE ESTERS OF A C2-C8 DIOL AND ACRYLIC OR METHACRYLIC ACID IS REACTED WITH A C4-C10 ANHYDRIDE OF A DICARBOXYLIC ACID, (2) THE ORGANIC REACTION PRODUCT OF THE FIRST REACTION STEP IS REACTED WITH A C2-C21 DIOL, AND (3) THE ORGANIC REACTION PRODUCT OF THE SECOND REACTION STEP IS REACTED WITH A SILOXANE HAVING TWO OR MORE HYDROXY OR ALKOXY FUNCTIONAL GROUPS PER MOLECULE. A SECOND METHOD FOR PRODUCING THESE RESINS ALSO INVOLVES A THREE STEP REACTION WHEREIN (1) A SILOXANE HAVING TWO OR MORE HYDROXY OR ALKOXY FUNCTIONAL GROUPS PER MOLECULE IS REACTED WITH A C2-C21 DIOL, (2) THE SILOXANE-COMPRISING REACTION PRODUCT OF THE FIRST REACTION STEP IS REACTED WITH A C4-C36 DICARBOXYLIC ACID OR ANHYDRIDE THEREOF, AND (3) THE SILOXANE-COMPRISING REACTION PRODUCT OF THE SECOND REACTION STEP IS REACTED WITH EITHER GLYCIDYL ACRYLATE, GLYCIDYL METHACRYLATE, OR A C5-C12 MONOHYDROXY ACRYLATE WHICH IS THE ESTER OF A C2-C8 DIOL AND ACRYLIC OR METHACRYLIC ACID.
