TSE 3941W 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).

FEATURES:

  • Meets the corrosion resistance requirements of MIL-A-46146A
  • Flame retardant UL rated, non halogenated
  • High thermal conductivity
  • Fast cure @ ambient temperature
  • Outstanding adhesion, including most plastics
  • Outstanding electrical properties
  • Resistant to heat, cold, moisture, UV, ozone and chemicals
