Mold Star 30 High Performance Platinum Mold Silicone

Mold Star 30 High Performance Platinum Mold Silicone

Mold Star 30 High Performance Platinum Molding Silicone Mold Star® silicones are platinum silicones that are mixed in a 1A:1B ratio by volume and are easy to use (no precision weighing required). Mold Star® silicones have relatively lower viscosities and vacuum degassing is not required for most applications.

Mold Star® 30 is a much harder material with a Shore hardness of 30A.


General features

Mold Star® silicones provide soft and strong silicone results that are resistant to breakage, and their long-term shrinkage margins are very low. Suitable for pouring wax, plaster, resin, concrete and many other materials, molds made with Mold Star® silicones can be kept in your mold library for a long time. Withstands temperatures of 450°F (232°C), cured Mold Star® silicone is also suitable for pouring low temperature molten metal alloys.

Note: Mold Star® silicones are not suitable for brush application.

Note: This product will not cure on sulphur-containing substrates, even when sealed.
