ELASTOSIL® Vario 15
- Chemical Family
- Silicones
ELASTOSIL® Vario 15 is a pourable, two-component silicone rubber that vulcanizes at room temperature through addition-curing. It can be blended with ELASTOSIL® VARIO 40 to achieve a desired hardness ranging between 15 and 40 Shore A. This versatile silicone rubber finds applications in prototype molding and reproduction molding.

- Application Details
Due to its resistance to all common reproduction materials. e.g. casting resins, concrete, plaster, as well as the mechanical properties, ELASTOSIL® VARIO 15 is especially suitable for all molds. As a low Shore A addition silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® VARIO 15 is also suitable if absolutely accurate copies of models are required.
- Storage Information
ELASTOSIL® VARIO 15 should be stored between 5 °C and 25 °C in the tightly closed original container. The 'Best use before end' date of each batch appears on the product label.
