EA-40 Clear Epoxy is an unfilled low-viscosity epoxy adhesive that can be spread easily in thin films that are almost transparent after curing. Mix ratio is 1:1 by volume. When mixed 2A:1B by volume, EA-40 will achieve greater heat resistance and improved physical properties.

EA-40 is versatile and can be used for many different assembly and repair applications ranging from electrical potting to jewelry assembly to repairing plumbing fixtures. Bow makers have come to know EA-40 as a tremendous laminating resin. EA-40 provides highly moisture resistant bonds meeting the performance requirements for Federal Specification MMM-A-188, Type III.
