5070 Epoxy
A low viscosity, optically clear epoxy
5070 is an electrically isolating epoxy that bonds well to most substrates such as metals, glass, ceramics, and most plastics. The material is free flowing for potting and underfill applications. With a refractive index of 1.54, it is ideal for optics applications.
This product will exotherm if cured at high temperatures in masses greater than 5 grams. Contact Appli-Tec for step cure instructions if curing in larger masses.
