POWERSIL® 3100 MH silicone rubber is a one-component, ready to use, addition-curing compound that cures to an electrical insulating, highly erosion resistive silicone elastomer.


POWERSIL® 3100 MH shows fast curing in comparison to conventional silicone rubber. Cure time is reduced by (30…50) % depending on the wall thickness and on the available machinery and runner system.


No peroxide decomposition products are released while curing. Due to the curing system there is no risk for curing inhibition by oxygen.


  • very good arc resistance
  • suitable dielectric properties
  • good mechanical properties

Spezifische Merkmale von POWERSIL® 3100 MH

  • kriechstromfest
  • Sehr gutes Hydrophobieverhalten
  • zweikomponentig

POWERSIL® 3100 MH cures rapidly at an elevated mold temperature (> 140 °C). It is designed to be used with sophisticated injection molding machines and molds.


For detailed information about processing please refer to the brochure ELASTOSIL® HTV-Silicone Rubber - Processing.


To achieve a good bonding between the typically used materials for electrical insulating equiment and POWERSIL® 3100 MH the primer G 800 should be used. It is available from Wacker Chemie AG as well.


The used catalyst system can be deactivated by the influence of some chemical products (e.g. amine derivates, sulphur products, tin compounds and phosphorous products). Please avoid contact to these chemical products.

Verpackung / Gebinde

POWERSIL® 3100 MH is commercially available in 700 kg cardboard boxes. Packaging in 20 kg cardboard boxes is available for sampling.


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.



Permanent transportation and storage at elevated temperature leads to a partly crosslinking and makes the material unusable.
