Abstract

A glass laminate consists of 2 sheets of glass bonded together by a layer of a plasticised polyvinyl acetal (polyvinyl butyral) treated with (a) a modified siloxane contg. 1-30(2-20) of each of the units: (where R1, R2 and R3 are hydrocarbon gps. (1-5C alkyl or phenyl), A is a (hydroxy-) is not > 20C(2-5C) alkylene gp. or a (hydroxy-) is not > 250C(6-100C) oxyalkylene gp., and B is OH, where R4 and R5 are alkyl gps. (pref. 1-5C), and A is oxyalkyelen if B is OH, or (b) the modified silane in combination with an alkali(ne earth) salt of a mono- or di-carboxylic acid. The laminated glass has higher resistance to penetration, without loss of transparency, or lowered resistance to ageing or weathering. The water contnt of the intermediate layer is not critical. The laminate is a safety glass or vehicles, boats or buildings.
