Tra-Con Tra-Bond 2119 Low Viscosity Glass Laminating Adhesive
Categories:	Polymer; Adhesive; Thermoset
Material Notes:	TRA-BOND 2119 is a crystal clear adhesive specifically designed for bonding glass to glass and glass to plastics. It also yields a high lap shear strength to metals and ceramics. This system cures to a semi-rigid hardness making it ideal for bonding dissimilar substrates especially when thermal cycling is required. This two part adhesive also has a low exotherm and therefore can be used for small pottings and filling bond gaps up to 1/8 inch. Information provided by Tra-Con Inc.
