PROBLEM TO BE SOLVED: To obtain an one-component type elastic adhesive excellent in balance of curing speed and storing stability having excellent adhesive manifestation to wet surface by compounding Portland cement as a filler to an one-component type epoxy resin based adhesive obtained by compounding a modified silicone resin to an epoxy resin. SOLUTION: This adhesive comprises (A) 100 pts.wt. of the epoxy resin, (B) 10 to 500 pts. of the modified silicone resin and (C) 10 to 200 pts. of the Portland cement. Preferably compounded with 50 to 200 pts. of the component B and 20 to 100 pts. of the component C. The preferable molecular weight of the component A is 300 to 1000. Poly(methyldimethoysilily ether) is cited as the component B. On the point of bestowing thixotropy, a surface processed calcium carbonate is preferably compounded as the filler other than the component C. Dehydrating agent, curing agent for the epoxy resin, curing catalyst for the modified silicone resin and a silane compound is preferably compounded. |
