TOMPS RAPIMOULD Addition Cure Range RTV Silicone Rubber. Following on from the mammoth success of Viscolo super low viscosity RTV silicone, we have developed Rapimould RTV. A super fast curing RTV when time is of the essence. Sold in 500g 2 pack bottles, this rubber has a potlife of around 4 minutes, and demould in under 20. Yes less than 20 mins from pour to pull! Torn your RTV mould in a rush? Still need a few more items quickly and dont have time to re-tool? THIS is for you. Have one on the shelf in case of emergency!

Rapimould is a superlative product outlasting all Condensation Cure Silicones and many (if not all!) Addition Cure Rubbers. Although this rubber appears un-branded, it is in fact manufactured by one of the world's leading RTV Formulators and Manufacturers. This Silicone resists PU Fast Cast very well.

Rapimould is the easiest system to use since it has a colour tag system to ensure full and even mixing. Being Specific Gravity Balanced, you may add these volumetrically or by weight. An accuracy of +/- 5% must be achieved, which is higher than most Addition RTV's error percentage, however outside this range cure cannot be guaranteed.

Key Information:

  • Potlife - 3-5 mins
  • Demould - 20 mins
  • Viscosity - 4000cps
  • Mix Ratio - 1:1 by weight or volume
