Laminated safety glass and polymeric laminate for use therein.

摘要

A polymeric laminate for use with a glass layer in a laminated bilayer or anti-lacerative shield application comprises a first layer of moisture tolerant plasticized polyvinyl butyral containing a) adhesion control agent(s) and b) residual hydroxyl content which optimize glass adhesion and optical performance over a range of moisture contents in the first layer likely to be encountered in use, i.e. 0.2 to 0.5 weight % and 2 to 2.8 weight %, such first layer being in face to face contact with a second layer of a clear polymer film or coating having a combination of performance properties desirable for these applications. Preferred second layers are biaxially stretched polyester and thermoset aliphatic polyurethane.
