An excellent general purpose silicone rubber used for mould making where minute surface detail needs to be reproduced and deep undercuts are present.

Silicone rubber has virtually no shrinkage and therefore will accurately reproduce dimensions and is an extremely durable material.

All packs include a curing agent, but to thicken silicone rubber and enable it to be 'buttered up' onto vertical surfaces to create a mould, add a thixotropic agent.
