Description

Kit consists of 2.5kg of PART A and 2.5kg of PART B 

Total kit volume 4.38 Litres

---

PART A is a grey liquid and PART B is a yellow liquid which are odourless and non-toxic. They react to form a strong, tough, flexible and elastic yellow rubber that resists pouring temperatures of up to 370°C.

The pot life is approximately 8-12 minutes and the cure time is 1-2 hours.

The two components mix easily with a simple 1:1 ratio and because of the low viscosity can be used without a vacuum chamber. There is practically no shrinkage (0.08%) and excellent reproduction of fine detail.

Primarily used for the casting of low melt alloys for casting military figures, jewellery, model parts and dolls house accessories in lead/tin alloys or pewter. It can also be used for casting resins, waxes, plaster etc.

*CURE INHIBITION*

A release agent will not create a sufficient barrier to prevent cure inhibition but a layer of paint will. If the paint is solvent based allow sufficient time for the solvent to completely evaporate off as that too can inhibit the cure.

Great care must be taken when handling and mixing all addition-cured silicone elastomer systems. All the mixing tools (vessels and spatulas) should be clean and constructed in materials which do not interfere with the curing mechanism. 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 these substances e.g. moulding clays, sulphur vulcanised rubbers, condensation cure silicone rubbers, some printed plastics, onion and garlic.

Shipping

We combine postage however ebay wont calculate the correct amount automatically. You will need to click the request a total from seller option whilst checking out so I can set it to the correct amount before you complete the payment. I do issue refunds on multiple orders if a total isn't requested. However ebay don't refund their fee on partial refunds so I have to deduct their fee (11%) from the saving.
