Adhesives and Epoxies Q&A
-
I need an epoxy to join two BK7 glass parts together. The gap is around 0.2 mm. Light will cross the interface, and a reasonable index match to the glass is required. Low stress and low shrinkage are necessary so that the adhesive doesn’t distort the parts. The viscosity should not be too runny, since we want it to stay in place prior to cure.Answered February 16th, 2010 by Expert:Optical glass bonding adhesives are available that have good adhesion to BK7 glass, a close refractive index match to the glass, low shrinkage (low modulus), and moderate viscosity to avoid running. You can use a light-curable adhesives such as OP-29, which is a one-part adhesive from Dymax that is exclusively available through the Fiber Optic Center (FOC; New Bedford, MA). The FOC also carries various two-part epoxies or one-part frozen epoxies that should meet your requirements. An alternative source would be to visit Edmund Scientific (Tonawanda, NY) and review their adhesive selections. Epotek 353-ND and 353-T epoxy are also widely used in the glass bonding and optical adhesives market.
