| 摘要 | Adhesive cements, which on curing will adhere to dry as well as wet surfaces, are prepared by mixing a monomeric ester of alpha -cyanoacrylic acid with a finely divided filler containing an amine activator. The preferred activators are the tertiary amines N,N-dimethyl-p-toluidine and N,N-dimethylaniline as time delayed but rapid setting is obtained through their use. With fillers such as finely divided quartz and alumina the effectiveness of the activator is substantially reduced on standing. To obtain a stable activated filler the filler is treated with a non-catalytic trialkoxysilyl compound prior to treatment with the amine activator. The non-catalytic trialkoxysilyl compound has a terminal group represented by the formula WHERE ANY ONE OF R, R1, and R2 may be -CH3 or -CH2CH3. | ||||||
