EXECUTION METHOD OF SEALANT

摘要

PROBLEM TO BE SOLVED: To strongly bond a polyisobutylene system sealant as a first sealant executed beforehand and a second sealant executed later without requiring much labor. SOLUTION: A second sealant is executed to a first sealant executed beforehand. In that case after an electrical discharge treatment is applied to the surface of the first sealant 2 executed beforehand, a polyisobutylene system sealant 3 is executed directly or through a primer. Therefore, the polyisobutylene system sealant executed later can be strongly bonded by applying the electrical discharge treatment to various sealants executed beforehand.
