FOAMABLE RESIN COMPOSITION AND PROCESS FOR PRODUCING FOAM

摘要

This invention provides a foamable resin composition divided into two or more discrete mixing components and which is foamed and set by mixing said discrete mixing components each other, wherein said composition comprises (A) an organic compound having a viscosity of 20 Pa.s or less at 23 DEG C and having a carbon-carbon double bond, (B) a compound having a hydrosilyl group, and (C) a foaming agent having a boiling point of 100 DEG C or lower and/or a compound having an OH group, each of said two or more discrete mixing components comprises one or more of said components (A), (B) and (C) and has a viscosity of 5 Pa.s or less at 23 DEG C. By preparing the two or more discrete mixing components having low viscosities and performing a foaming/setting process in which these discrete mixing components are sprayed or infused after mixing or with mixing, a foam having a high expansion ratio and a fine cell can be obtained.
