5051 Epoxy
A low viscosity, optically clear epoxy
An electrically isolating epoxy compound, 5051 bonds well to most substrates such as metals, glass, ceramics, and most plastics. The material is free flowing, making it ideal for potting and underfill 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.
