Elastic adhesive | Thermal Conductive Elastic AdhesiveSX-TCA series

Features

  • Forms a highly thermally conductive elastic body and offers long-lasting thermal radiation at a high level.
  • Contains no low-molecular silicones, which can cause electrical contact failure.
  • Can be used to reduce screw usage due to its adhesion and adhesive reliability.
  • No compound bleeding and no shrinking – can be used as a curable grease.
  • Curing/half-curing, preventing pump-out.
  • Excellent adhesion and durability make it suitable for heat management solutions for vertical surfaces and parts affected by vibration.
  • Fast-curing, improving work efficiency.

No concern for pump out (compared to grease)
