Chemically Resistant adhesives

Henkel Loctite® Output™ 5404 Heat Cure Silicone
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes:
Thermally Conductive Bonders
Loctite® Thermally Conductive Adhesives eliminate the need for mechanical fasteners and clips, while providing the most efficient thermal transfer between transistors or microprocessors and their heat sinks. Loctite offers a wide range of adhesive chemistries including silicones, acrylics and epoxies. Many processing options are available for curing these adhesives such as heat cure, activator cure, and UV light.

Loctite® 5404 1 component silicone Output™ Heat Cure Silicone
A self-shimming, flexible adhesive for demanding parts such as ceramic boards. Cure Type: Heat
