PURPOSE:To obtain an agent for accelerating of bonding, protecting of bonded part and maintaining high bonding property between inorg. materials, by compounding a surface active agent with an aq. soln. obtd. by adding silicate compd. to an aq. hydrolyzate soln. of organoalkoxysilane and by adjusting the pH to specified pH value. CONSTITUTION:The agent is one for accelerating and protecting bonding for the second inorg. material to be bound with the hydraulic or air setting first inorg. material and contains the aq. soln. (A) adjusted the pH to 9-13pH value by adding at least one kind among silicate salt compds. to the aq. hydrolyzate soln. obtd. by hydrolyzing at least one kind among organoalkoxysilanes with water, and the surface active agent. The used organoalkoxysilane is one expressed with formula. In the formula, R<1> is methyl-, ethyl- or amylphenyl- group, R<2> is ethyl-, amyl- or vinyl-group, R<3> is methyl-, ethyl-, propyl-, butyl- or acetyl-group, a is 0-3, b is 0 or 1 and a+b<=3. |
