HT 33 Red (33 ShA)

DescriptionDetailDownload

HT 33 RED is a bi-component addition cured RTV silicone rubber which vulcanises at room temperature.
Compatible with all plasters, coatings, polyurethane resins and acrylic resins.

Main application sectors

  • Mould making and model-making due to its considerable precision in reproduction,  high dimensional stability and mechanical resistance
  • Ceramic serigraphy due to its considerable precision in reproduction and  excellent laser cutting characteristic

Properties

  • High chemical resistance to the aggressive components of some types of resin
  • Good resistance to laceration (high resistance to wear and tear)
  • Considerable accuracy in the reproduction of very small details
  • High dimensional stability over time and non-deformability
  • Considerable resistance to high temperatures and to ageing
  •  Excellent non-stick effect
