Elastic adhesive | Thermal Conductive Elastic Adhesive SX-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)
