INTRODUCTION OF MOMENTIVE TSE3941W
MOMENTIVE TSE3941W is one-component, fast curing silicone adhesive sealant that cures on exposure to atmospheric moisture to form an elastic silicone rubber. Has excellent corrosion-free adhesion to metals, including copper, plastics, ceramics, glass, etc without the use of primers.
TSE3941 flame retardant adhesive/sealants are non-flowable, one-component RTVs that cure quickly by reacting with atmospheric moisture forming a soft elastic silicone rubber. These materials incorporate newly developed crosslinking chemistry and are non-corrosive to metallic substrates. They are particularly well suited for electrical/electronic applications.
These products differ in color and flame retardancy; TSE3941 is white and is UL94 V-1 rated. When cured, they retain their elastomeric properties throughout the operating temperature range of -55C to 200C (-67F to 392F).
KEY FEATURES

- Flame retardant UL rated, non halogenated
- High thermal conductivity
- Fast cure @ ambient temperature
- Outstanding adhesion, including most plastics
- Outstanding electrical properties
