TIS680-28AB — Product overview
TIS®680-28AB is a two-component potting adhesive. When Component A and Component B are mixed in a specific ratio, the adhesive can cure and form into shape either at room temperature or under heating conditions. After curing, it forms a dense elastomer with integrated performance characteristics: excellent thermal conductivity, electrical insulation, resistance to extreme temperatures, and anti-aging properties. It features low shrinkage rate, can closely adhere to various substrates, and effectively fills the gaps between electronic components. This product delivers comprehensive protection for electronic assemblies, including thermal conduction, insulation, waterproofing, shock absorption, flame retardancy, and mechanical safeguarding.
