1. Product Overview

BERGQUIST LIQUI-BOND TLB SA1000 is a one-part, thermally conductive liquid silicone adhesive designed for thermal management. It combines high thermal performance with excellent chemical and mechanical stability, even under extreme environmental conditions. The adhesive eliminates the need for mechanical fasteners, enables very thin bond lines, and offers mild elasticity to relieve stresses caused by thermal cycling. It cures with heat, contains no cure by-products, and requires refrigerated storage at 10 °C.


2. Applications

  • Bonding PCBA to housing for improved heat transfer.

  • Attaching discrete components to heat spreaders.

  • Suitable for environments requiring reliable thermal conductivity, stability, and flame resistance (UL 94 V-0).
