HT 45 TRANSPARENT silicone is a two-component RTV rubber, which is especially recommended for making ceramic and concrete moulds.

It is also well suitable for use with a polyurethane resin, acrylic resin, epoxy resin and polyester resin. Still, it does not adhere to plasters, coatings, or paints.

Main Application Areas:


mould production and modeling with significant reproductive accuracy. It has high dimensional stability and excellent mechanical strength.

It is used predominantly for artistic pottery.
Its high tear resistance and tensile strength make it suitable for concrete casting.<>>> >>>>>>>>>>Also, mockup builders and model makers used to replicate smaller plastic parts with simple geometry, small and not too large undercuts.

Its high transparency and rigidity make it suitable for casting parts with slim wall thickness .

High-temperature casting is possible. Wax, candle material, and even low-melting metal like a tin can also be poured into HT 45 TRANSPARENT silicone mould.

The curing process may be prevented by the following:

You have to take special care when using additive silicone systems.

While you handle and mix the silicone elastomer components, make sure that all mixing tools (vessels, spatula, mixer, etc.) are clean and made of materials that do not affect the curing process or chemical reaction.

Do not use wood and paper mixer!

The following materials may also inhibit the polymerization of the silicone resin:

  • the presence of nitrogen, sulfur, phosphorus and arsenic
  • compounds
  • organic tin catalysts
  • PVC stabilizers
  • epoxy resin catalysts

In addition, the following materials, products or materials containing them should also be kept away.

  • moulding clay
  • sulfur vulcanized tires
  • condensation silicone rubber
  • wood, paper, onion and garlic.
