Momentive TSE326M

Description

Momentive TSE326M

Momentive TSE326M (also known as TSE326) is a one-part, heat-curing silicone adhesive engineered for assembly, sealing, and gasketing applications that demand high thermal resistance and reliable adhesion. It cures quickly when exposed to heat, forming a durable, resilient elastomer that adheres to a wide variety of substrates including aluminum, steel, glass, and most plastics—often without primer.

This non-corrosive silicone offers low shrinkage, outstanding dielectric strength (22 kV/mm), and mechanical flexibility for long-term stability in high-heat environments. It’s widely used in electronics, automotive, and industrial assemblies for bonding and sealing components subject to thermal stress.

Momentive recommends SS4155 silicone primer when stronger chemical adhesion is needed for difficult substrates.
