Addition Cure RTV Silicone Rubber. Also called Platinum Cure Silicone, a harder wearing silicone with zero shrink. Made to our specification by a leading silicone manufacturer, it carries the TOMPS brand. Why would you use an addition cure instead of a condensation cure?

• Exceptionally Low Shrinkage - Zero if the process is followed correctly base
• Dimensionally Stable - The negligible shrinkage means that angles remain true, one reason why this rubber is used in larger toolings
• Excellent Library Life - If you want a silicone to store on the shelf and it to remain true, select addition cure
• Lower Viscosity - Our Addition RTV has one of the lowest viscosities of any RTV
• Better Chemical Resistance - Tested without mould release with Urethane Fast Casts to 100+ pulls
• Easy Mix Ratio - 1:1 by weight or volume. Balanced SG's allows volumetric or weight measures

The only downside to Platinum Cure Silicones is their cure inhibition problems. Due to the chemical processes involved certain products will poison the RTV including sulphites, sulphur, platiscisers, latex gloves (use vinyl or synthetic or just dont touch the material!) onion and garlic vapours and juices. We now only stock Viscolo 22 as we were unhappy with the library properties of Viscolo 13.
