Encapsulant catalysts, sometimes referred to as hardening agents, are designed to initiate or speed up an encapsulant's curing process. Catalysts can also be used to alter the workability of the encapsulant based on application needs. These materials are usually designed to work with a specific encapsulant, making it important to ensure compatibility before purchasing. Ellsworth Adhesives supplies encapsulant catalysts from Henkel Loctite, ELANTAS PDG, and Dow with a variety of available cure systems.
