PoolKemie KEMIEPOX EL BLACK Casting epoxy resin
Categories: Polymer; Thermoset; Epoxy

Material Notes: Introduction: Two component room temperature vulcanizing compound based on suitable filled epoxy resins which cures with an appropriate hardener. KEMIEPOX EL Black is free from solvents and plastifiers, is very hard and has an excellent dimensional stability. In addition to this, it is characterized by a very good electric and mechanical resistance and chemical stability.

Application: KEMIEPOX EL BLACK is designed for manufacture of foundry models and moulds, insulation of electric circuits, creation of prototypes and insulation of acoustic equipments to avoid sound-waves scattering.
