Abstract

PURPOSE: To obtain an effective primer for enhancing the adhesion between a porcelain pipe and a urethane-sealed part in contact with water by using a solution containing a silane coupler and a polyphenylmethane polyisocyanate(prepolymer).
CONSTITUTION: A 1:(1.1W200) (equivalent ratio) mixture of a silane coupler (A) (e.g., γ-aminopropyltrimethoxysilane or γ-mercaptopropyltrimethoxysilane,) and a polyphenylmethane polyisocyanate (prepolymer) (B) (e.g., diphenylmethane 4,4'- diisocyanate) is dissolved in an organic solvent to obtain a primer. The primer thus obtained is applied on the joint surface of porcelain pipes, a urethane sealant is injected into the aperture between the joint of the porcelain pipes and a mold, and hardened for joining the poecelain pipes.
