METHOD OF COATING MOISTURE-CURING SEALING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method of coating the surface of a cured sealing material containing a polyoxyalkylene-based polymer having a crosslinkable silicon group, and of performing the coating excellent in adhesiveness of a coating material to the sealing material.

SOLUTION: The cured material surface of a moisture-curing sealing material is coated with the coating material containing 1-50 pts.wt. of (B) alkylphenol resin based on 100 pts.wt. of (A) polyoxyalkylene-based polymer having a hydroxy group or hydrolyzable group bonded to a silicon atom and having the crosslinkable silicon group crosslinkable by forming a siloxane bond by moisture.
