Safety Clear Coat

Composites in Manufacturing, Third Quarter 2005

Devcon's (Danvers, Mass.) new Safety Clear Coat(TM) seals and protects glass, metal, ceramics, wood, phenolics, composites, fabrics and concrete against impact and wear in a variety of OEM applications. This self-leveling liquid adhesive is water clear, maintains its clarity overtime and provides superior flexibility (tensile elongation 150%) and UV stability.

It can also be used to form a transparent protective barrier that can minimize shattering of delicate or fragile items. Safety Clear Coat is a 100% solid, 1:1 epoxy formulation with no VoC emissions. It has a mixed viscosity of 3,500 cps, a working time of 30-40 min. and a functional cure time of 8 to 10 hr. After 24 hr, the adhesive provides a tensile lap shear strength of 1,200 psi (per ASTM D1002 on grit-blasted steel), a peel strength of 50 pli, an impact resistance of 15 ft-lb/in^sup 2^ and a hardness of 55 Shore D. It offers excellent resistance to hydrocarbons and withstands service temperatures from -40°F to 175°F (-40°C to 79°C) [dry].
