ELASTOSIL® P 7683/25 A/B

Addition-curing RTV-2 silicone rubber curing to a silicone elastomer of very low hardness.


Properties

  • low viscosity, easily pourable
  • mixing ratio 1 : 1
  • fast cure at room temperature which can be accelerated considerably by the application of heat
  • low hardness Shore 00 (~ 25)
  • translucent vulcanizate

Specific features of ELASTOSIL® P 7683/25 A/B

  • Addition Curing
  • Fast curing at room temperature
  • Flowable
  • Suitable for skin contact
  • Two-component


ELASTOSIL® P 7683/25 A/B can be used for molding applications in prosthetics.

Components A and B of ELASTOSIL® P 7683/25 A/B are homogeneously mixed in a ratio of 1 : 1 and vulcanize rapidly at temperatures above 100 °C. In a given application the required curing conditions (temperature and time) will also depend on the size and thickness of the specimen.

 

Detailed instructions for preparation and use are given in the brochure “Room Temperature Vulcanizing (RTV) Silicones - Material and Processing Guidelines”


Important note:
The platinum catalyst is in component A.

Caution!
Only A and B components with the same batch number may be processed together!

Storage

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
