Paste

An adhesive compostion, of the 'instant adhesive' type, comprising:

(a) from 77 to 95% by wight of monomeris 2'-ethoxyethyl 2 cyanoacrylate;

(b) from 3 to 15% by wight of a poly-(C1-5) alkyl acrylate of methacrylate having an average molecular wight within the range from 400,000 to 600,000;

(c) from 2 to 8% by wights of hydrophobic fumed silica; and

(d) from 100 to 1000 ppm by wight of a polymerization stabilizer;

A cyanoacrylate adhesive composition in thixotropic paste form is made by mixing a liquid cyanoacrylate ester with powdered organic fillers selected from (i) polycarbonates, (ii) polyvinylidene fluorides, (iii) polyethylenes, and (iv) acrylic block copolymer resins containing saturated elastomer segments. Concentration of the filler is about 5 to 100 parts by weight. Particle size of the filler is about 2 to 200 microns.
