Thermally Conductive Potting Compounds, ZS-GF-5299Z-3

ZS-GF-5299Z-3 RTV Silicone Potting Compounds Description

The ZS-GF-5299Z-3 RTV silicone potting compounds is a medium viscosity, two-component, high thermal conductivity silicone sealant. It cures via heating and cures faster with a higher temperature. This product releases no byproduct when curing, making it applicable to substrates that include metals and plastics such as PC(Poly-carbonate), PP, ABS, PVC, and more. Temperature range of -60℃ to 220℃. And fully meets EU RoHS and REACH standards.

Typical applications

Potting, encapsulating and thermal protection of power modules and other electronic components
