ELPECAST® casting compounds

ELPECAST® casting compounds protect and insulate electronics, sensor technology and lighting electronics against extreme weather conditions and aggressive media. A large variety of transparent and opaque products fulfills numerous individual requirements and customer requests.

a large variety is available in terms of viscosity, colours, processing time and pot life; numerous hardness and elasticity adjustments cover the full range of shore hardness; good resistance against water, moisture, lyes, acids and many chemicals; elastic adjustments are a low-cost alternative for silicone casting compounds
