Abstract:
PROBLEM TO BE SOLVED: To provide a two-liquid type honeymoon adhesive whose components disperse through each other at the rate faster than reacting to each other after the adhesive is coated on a surface. SOLUTION: The honeymoon adhesive contains the first agent and the second agent which are separately present. The honeymoon adhesive comprises at least three components selected from a polymer containing a reactive silyl group, a catalyst and water. The first agent comprises at most two kinds of above components. The second agent comprises at least the third component. Also, either of the first and the second component does not comprise all of three components. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a flame retardant humidity curing type composition having excellent performance as an adhesive or fixing agent for electric products or precision instruments which require flame retardant property, and to provide a flame retardant humidity curing adhesive composition comprising the composition as an active ingredient and to provide an adhering method using the same. SOLUTION: The flame retardant humidity curing type composition comprises 100 pts. by mass (abbreviated as pts. in the following) of (A) an organic polymer containing a reactive silicone group, (B) 150-350 pts. of a metal hydroxide having 0.1-200 μm of average particle diameter, (C) 0.1-15 pts. of hydrophilic silica, and (D) 1-50 pts. of surface treated calcium carbonate having 0.01-10 μm of average particle diameter as essential components.
