2 component transparante additie silicone voor het maken van negatief mallen.
Toepasbaar in:
Model makers door zijn hoge precisie in reproductie , duurzaamheid en hoge mechanische sterkte
Tampon drukken voor zijn hoge mechanische weerstand
Eigenschappen:
- Reduced viscosity and easy to mix
- High chemical resistance to the aggressive components of some types of resin
- Good resistance to laceration (wear and tear)
- High level of accuracy in reproducing very small particulars
- High dimensional stability over time and non-deformability
- Considerable resistance to high temperatures and to ageing
- Excellent non-stick effect
