Flame Resistant Grey Silicone Potting Compounds, ZS-GF-5299S

ZS-GF-5299S RTV Silicone Potting Compounds Description

The ZS-GF-5299S RTV silicone potting compounds are supplied as a low viscosity, two-component silicone kit for potting. It cures at room temperature or by heating, with a faster curing at higher temperatures. No byproducts are produced during the curing process, allowing it to be used as substrates for metals and plastics, including PC (Poly-carbonate), PP, ABS, PVC, and more. Temperature range of -40℃ to 200℃ and conforms to EU RoHS and REACH standards.

Typical applications

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