T-15 RTV Silicone Rubber is a two-component, high strength, flexible, moulding compound.  Moulds made with T-15 is excellent for casting many materials including polyester, epoxy and polyurethane resins. T-15 is addition-cure, platinum-catalysed and offers advantages over tin-catalysed systems in certain applications, because on curing they don’t shrink, they don’t produce alcohol (which can inhibit urethane castings), and their cure can be heat accelerated.

T-15 Advantages.

  • Low viscosity for excellent reproduction of details and easy degassing
  • Easy mix ratios – can use with dispensing machines
  • Cure at room temperature or accelerate with heat
  • Easy release properties –save on release agents
  • High tear strength – fewer prematurely torn moulds
  • Good chemical resistance for longer mould life
  • Low/zero shrinkage for better dimensional reproduction
  • Shore A hardness of 15

MB Fibreglass believes that the information above is an accurate description of the typical characteristics and/or uses of the product or products, but it is your responsibility to thoroughly test the product in its specific application to determine performance, efficacy and safety.

Inhibition of Cure

Great care must be taken when handling and mixing all addition-cured silicone elastomer systems, that all the mixing tools (vessels and spatulas) are clean and constructed in materials which do not interfere with the curing mechanism, do not use wood and paper mixing utensils. The cure of the rubber can be inhibited by the presence of compounds of nitrogen, sulphur, phosphorus and arsenic; organotin catalysts and PVC stabilisers, epoxy resin catalysts and even contact with materials containing certain of these substances e.g.. moulding clays, sulphur vulcanised rubbers, condensation cure silicone rubbers, wood, paper, cardboard, onion and garlic.

Base and catalyst use universal containers for various kit sizes and are supplied by weight, while the supplied containers may not be full, they will contain the correct amount of both base and hardener according to the listing. At point of packaging and dispatch lids may be taped to prevent damage or spillage during transportation.
