ZA 4 LT Red (4 ShA)


ZA 4 LT RED is a bi-component addition cured RTV silicone rubber which vulcanizes at room temperature. Due to the considerable fluidity it is recommended for the duplication of models with accentuated undercuts.
Compatible with all plasters, coatings, polyurethane resins and acrylic resins.

Main application sectors

  • Mouldmaking and model-making due to its considerable precision in reproduction, high dimensional stability and high mechanical resistance
  • Ceramic serigraphy due to its considerable precision in reproduction, high mechanical resistance and excellent laser cutting characteristic
  • Tampography due to itshigh mechanical resistance and excellent ink transfer property
  • Podology due to its high levels of softness and skin compatibility

Properties

  • High chemical resistance to the aggressive components of some types of resin
  • Good resistance to laceration
  • High level of accuracy in reproduction
  • High dimensional stability over time
  • Considerable resistance to high temperatures and to ageing
  • Excellent non-stick effect
