Rate item

Description

Talcum is a magnesium silicate hydrate which is used as an important reinforcing, filling and lubricating agent.

Talcum is used to fill polyester, vinyl ester and epoxy resins, e.g. for the production of artificial stone and levelling compounds. Talcum reduces shrinkage during curing and leads to improved sandability of levelling compounds, but reduces their hydrolysis resistance. Talcum is free of asbestos and quartz.

  • Produces very light, easily sandable fillers
  • Reduction of shrinkage of resin systems
  • Improvement of some mechanical properties
  • Thickening of resins
  • Mould powder for metal casting in silicone, see eWiki
