Epoxy

The Emcast 1790 family of delayed-action UV-curable epoxy products is designed to allow two opaque parts to be glued together using a UV adhesive. These products can be used for small-assembly projects and laminations. The adhesive is applied and irradiated with longwave UV light (325 to 380 nm), then, depending on formulation, UV intensity and duration, the surface-skin cure is delayed by seconds or minutes. A short heat post-cure after the parts are mated reportedly will hasten the final cure. There are four standard products in this line of epoxies and several experimental products, some of which are said to have UV-exposure times as low as 0.2 seconds.
