Autex, an important supplier to the international epoxy industry, has recently developed a new type of epoxy resin that is photocured under UV irradiation. This resin contains a new initiator called Photolatent Polymerization Initiator.

It is reported that since no thermosetting treatment is required, this new type of epoxy resin material has the excellent characteristics of improving production efficiency, reducing heat consumption and exhaust gas. In addition, this new material has the advantage of resistance to electrolytic corrosion. The company has plans to expand the sales market for various new materials, including replacing traditional acrylic materials for optical components, precision bonding and electronics industries.

Photolatent polymerization initiators developed by Autex have been industrially produced, and are catalysts composed of metallocene compounds and borate compounds. It is said that this initiation-catalyst can be used for almost all types of epoxy resins, including alicyclic, bisphenol A, and novolac epoxy resins.
