Product description

Silicone condensation HT 60 Set Wacker 4470 + T 40 Set

The silicone condensation HT 60 is a 2-component condensation curing casting silicone that cures at room temperature. The silicone is highly filled and suitable for the production of moulds for low temeprature alloys like Zamak, tin or lead.

Because the silicones are highly filled they tent to break when bent too far. Therefore  we advise not to use this siliconen for moulds with may or large undercuts.

  • Color: Red-Brown
  • Easy to mix
  • Short-term heat resistant up to 380 ° C
  • Very hard. Shore A 60

Technical specifications

  • Mixing ratio (in weight): A:B = 100:2
  • Pot life at 20°C: 40 Minutes
  • Demoulding at 20°C: 4 hours
  • Full strength after: 3 days
  • Hardness: Shore A 60
  • Viscosity at 20°C: 11.000 mPa's
  • Tear strength: 45 Kg/cm2
  • Color: Red Brown

Note: Pot life and demold time are dependent on the mixing ratio and Humidity. Addition of more than 2% silicone B (harder) or working at higher humidity will shorten pot life and demould time.


The fillers in the A-component must be mixed thoroughly before use.

The silicone C HT 60 can easily be mixed by hand or by machine. Mix the components thoroughly in the ratio indicated. Process the mixture within the pot life and de-mould after the whole thing is completely cured. Make the mould as thin as possible.

After cure, post cure the rubber mould by putting it in an oven for 2-3 hours at 150 ° C to remove trapped vapors. Coat the mold (prior to casting the alloy into it) with a layer of talcum powder or graphite powder, this will improve the wetting of the alloy onto the mould surface. Make sure that the mold is heated prior to csating the alloy. Put the mould on a surface with a high thermal conductivity.


The standard package contains 1 kg A-component and 20 g B-component. For larger quantities please contact us via the webshop.

Shelf life

When stored in sealed packaging at a temperature of 10-25 ° C, the shelf life is at least 1 year. If the A component has been on the shelf for long, the fillers should be stirred well before use.


If you frequently work with silicones, it is recommended to wear gloves during processing and to ventilare the room well. Please refer to the Material Safety Data Sheet for more information.
