Title:
CURABLE SILICON-CONTAINING POLYETHER ADHESIVE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1995/026998
Kind Code:
A1
Abstract:
A sealer or adhesive composition based on a polyoxyalkylene polymer having a silicon-containing hydrolyzable group, which has improved compatibility with a base or first paint coat containing acrylic resins. The improvement involves the addition and admixture to such a sealer/adhesive composition of a polar organic solvent material having both a Snyder's polarity value in the range of from 6.2 to 7.3 and belonging to Snyder's selectivity group III. In a method of the present invention, the inventive sealer/adhesive composition is wet-on-wet overcoated by a base coat or first coat of a multi-coat paint system, where the base coat incorporates acrylic resin, pigment and auxiliary polar solvents, while retarding and even completely preventing adverse surface defects in the base coat upon its drying (curing), such as cracking or wrinkling therein, to provide an improved coated substrate.
