Characteristics

Aurosil C Lab 85 is a condensation silicone characterised by optimal hardness and very good mechanical properties. The material is suitable for many laboratory procedures requiring a short working time and processes carried out at moderate temperatures.

Aurosil C Lab 85 silicone is recommended for protecting teeth during the flasking of removable dentures. It can also be used for making preliminary matrices for preparing gingival masks in the indirect technique, as well as matrices used in the fabrication of dentures made from self-curing acrylics. The material is also suitable for other related laboratory applications, such as quick working models for repairs of removable dentures. A gel catalyst is required for proper curing.

Advantages

  • Optimal balance between the material’s rigidity and elasticity
  • Well-balanced ratio of working time to curing time
  • Compatibility with other catalysts for C-silicones
  • Does not stick to hands or to the measuring spoon used
  • The material has a pleasant vanilla scent
  • Easy shaping at the initial stage of work and optimal hardness after polymerisation is complete
  • Thixotropic properties
