Product Introduction
Momentive TSE3925-C is a single-component, room-temperature curing (RTV), alkoxy-type adhesive sealant featuring a significantly reduced content of low molecular weight siloxanes. By reacting with ambient moisture in the air, this product cures into a resilient, rubbery elastomer that delivers exceptional heat resistance, cold resistance, electrical insulation, weatherability, and water resistance.
It is characterized by a fast tack-free time, remains completely non-corrosive to metals (including copper and copper-based alloys), and exhibits outstanding adhesion to a wide range of substrates, including metals and plastics. The “-C” suffix designates its clear (translucent) appearance.
Momentive TSE3925-C Features:
- Utilizes a single-component, fast-drying alkoxy condensation cure system.
- Features a significantly minimized volatile low molecular weight siloxane content.
- Provides excellent unprimed adhesion to diverse substrates such as metals, plastics, ceramics, and glass.
- Non-corrosive to metals (including copper-based materials) and successfully passed the MIL-A-46146B corrosion test standard.
Momentive TSE3925-C Applications:
- Specially engineered for moisture-proof and airtight bonding and sealing in electrical and electronic equipment.
- Ideally suited for the potting, encapsulation, and conformal coating protection of hybrid integrated circuits (ICs), printed circuit boards (PCBs), and electronic assemblies.
- Widely utilized for general-purpose industrial bonding of metals, glass, plastics, and other materials.
