Overview

To increase the speed of UV-curing resins, the amount of polymerization initiators is increased. In the case of epoxy resins, the temperature is increased. However, when multifunctional-Thiol∗-based Karenz MT™ PE1 is used, curing speeds are substantially improved. Karenz improves adhesiveness and elongation, as well as reduces the amount of energy used for production and processing.

The use of Karenz MT™ PE1 in UV-curing resins helps reduce the amount of UV irradiation and polymerization initiators, which restrict the coloring of the product. In the case of epoxy resins, it is possible to cure at low temperatures and increase the curing rate compared with the use of conventional amine-based curing agents*. Furthermore, compared with conventional Thiol-based curing agents, Karenz MT™ PE1 has lower levels of odor.

1. UV-curing resins: A photo-curing resin that changes its properties following irradiation of ultraviolet rays. It is used as a coating material and as photoresist in the production of electronic circuits.
2. Multifunctional-thiol: Compounds whose molecule contains two or more groups of hydrogenated sulfur (-SH).
3. Amine-based curing agents: Curing agents whose molecule contains amino groups (-NH2), reacting with epoxy resins at room temperature for curing.
