CYANOACRYLATE ADHESIVE COMPOSITIONS FOR BONDING GLASS

摘要

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 selected from the silanes of the formula: R'(4-n) Si(OR")n wherein: n = 1 to 4; and each R' and R" which may be the same or different represents H, hydrocarbyl, aryl, hydrocarbylaryl or a substituted derivative thereof, or those of formula (I) wherein R1, R2, R3, and R4, each independently represents 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.
