Encapsulant Chemistries

Silicone Encapsulants

Silicone encapsulants are softer than epoxy variants and provide better protection under stresses in many cases. Silicone encapsulants are a good choose when PCB protection requires materials with the ability to absorb of different types of shocks. Our silicone encapsulants allow for different application and curing methods based on your manufacturing processes. 

Epoxy Encapsulants      

Epoxy encapsulants are stronger and more reliable than silicone or acrylic encapsulants making them the choice for many manufacturers. Epoxy encapsulants provide a strong outer casing and overall adhesion is better with epoxy chemistries. This also includes liquid epoxy encapsulants for semiconductor packaging applications. Henkel’s product line includes epoxy resin dams that provide a strong dam area for dam and fill application methods.  

Urethane Encapsulants

Urethane encapsulants are generally not as hard as epoxy and provide excellent protection of electronic components especially for potting applications. Urethane encapsulants are usually used for overall protective coatings and come in two component formulations.

Acrylic Encapsulants

Acrylic encapsulants are UV/heat curable and are ideal for encapsulation applications that the require flexible and stability. Acrylic encapsulant chemistries are both effective against external environmental factures and pressures as well as help protect against heat making them important for many encapsulation applications.
