Momentive TSE382-C Waterproof Electrical Silicone Adhesive Sealant

Basic Properties

Product Overview

Momentive SNAPSIL™ TSE382-C is a one-component, oxime-cure silicone adhesive sealant that cures at room temperature via ambient moisture. It bonds to metals, plastics, ceramics, and glass without primers, featuring a neutral cure (with corrosion risk to copper/copper alloys). The product delivers exceptional high/low-temperature resistance (-55°C to 200°C continuous), weatherability, ozone resistance, and chemical stability. UL-recognized (File E56745) with UL746 TI Elec. 150°C/Mech. 140°C and UL94 HB ratings.

Enhanced Attributes

Dielectric Properties: Volume resistivity of 1×10¹⁵ Ω·cm and dielectric strength 23 kV/mm (after 7-day cure), ideal for high-reliability electronics.
​Substrate Adaptability: Graded adhesion solutions for challenging substrates like copper (△), stainless steel (△), and nylon 66 (requires primer YP941).
​Safety Compliance: UL certification ensures mechanical/electrical safety in sealed electronics.
​Limitations: Poor adhesion to non-polar plastics (e.g., PE, PTFE, marked "X" in TDS).

Applications

1. ​Waterproofing Electronics: IP67 sealing for telecom enclosures and sensor interfaces (Source: Momentive TSE382 Tech Manual).
2. ​Automotive Oil Leak Prevention: Gasket sealing for engine blocks and oil pans, resistant to lubricants and vibration (TDS).
3. ​Solar Module Sealing: Junction box adhesion in PV panels, passing IEC 61285 damp-heat tests (Source: Momentive Case Studies).
4. ​Medical Device Encapsulation: Airtight sealing for ventilator sensors, biocompatibility per ISO 10993-5 (Source: TSE382-C Medical Application Report).
