Two-component silicone for molds is a modern material that is ideal for creating precise and durable molds. It consists of two components: a base and a hardener, which are mixed in a certain proportion before use. After hardening, the silicone becomes elastic, resistant to deformation and able to accurately convey the smallest details of the model.
Main characteristics:
High detail– perfectly follows complex contours and textures.
Elasticity– allows easy removal of finished products without damaging the mold.
Durability– withstands multiple pouring cycles while maintaining its properties.
Heat resistance– suitable for working with materials that require heating (e.g. epoxy resin, wax, gypsum).
*Flash point > 250 °C Auto-ignition temperature 450 °C > Decomposition temperature 200 °C >
Ease of use– simply mix the components and pour the mixture into the prepared model.
Application: Two-component silicone is widely used in various fields:
Creativity and handicrafts– creation of molds for casting from resin, plaster, wax, soap.
Manufacturing– production of decorative elements, souvenirs, jewelry.
Casting– production of parts with high precision.

The use is very simple. After you have homogenized the silicone rubber, add the catalyst (mix ratio 100:5) and mix both by hand and by a mechanical mixer. To reduce air bubbles, we suggest a vacuum de-airing treatment before pouring the silicone rubber, compatible with the vulcanizing working times. Vulcanization is influenced by temperature and moisture. The best curing conditions are at 23°C and 50% relative humidity. The use of products at higher temperatures and/or higher relative humidity levels will reduce pot life and setting time. As opposed to this, lower temperatures and lower relative humidity levels will increase pot life and setting time. If the amount of catalyst is increased from 5 to 6-7%, the curing will accelerate, but shrinkages will increase too. It is recommended not to use the product at temperatures lower than 20°C. In these conditions, the final product performance will be difficult to achieve. We always suggest to clean the mould to reproduce from dust and grime. If the object is glass-made or ceramic-made, it is sometime possible that the silicone rubber can stick together to the object. In those cases, we suggest to use release agent.
