Abstract

A one-part adhesive composition for bonding glass including:(a) a cyanoacrylate monomer;(b) 15 to 60% w/w of at least one plasticizer by weight of the composition;(c) 0.01% to 5.0% w/w of at least one silane by weight of the composition. The silane may be is selected from the silanes of the Formula:R′(4−n) Si(OR″)nwherein: n=1 to 4; andeach R′ and R″ which may be the same or different represents H, hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof, or those of the formula: wherein R1, R2, R3, and R4, each independently represent hydrocarbyl, aryl, hydrocarbylaryl, or a substituted derivative thereof, H or halogen or the group —OR5 wherein R5 represents hydrocarbyl, aryl or hydrocarbylaryl or a substituted derivative thereof and any two of the groups R1, R2, R3 and R4 may be taken together with the silicon atom to form a cycle;with the proviso that at least one of R1, R2, R3 or R4 represents hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof.
