SentryGlas® Interlayer is a structural interlayer designed to be laminated between two or multiple layers of glass and used in applications where high performance glass is required. Originally developed for the security and hurricane glazing markets, SentryGlas® interlayers are also being used for ballistic and forced entry glass, transportation, exposed edge glass, and structural load bearing glass such as stairs, flooring, and canopies.
SentryGlas® Interlayer is available in two grades. SentryGlas® (SG5000) and SentryGlas® XTRA™ (SGX™) (SG6000) which does not require the use of an adhesion promoter. Please ask your Curbell Plastics representative for more specific information.
