Polyurethane Fast Cast Resin for casting and tooling. This is one fantastic fast cast that has most of the small scale scenery manufacturers in a spin over its properties! With a 3-4 minute potlife and around 30 minutes to cure, this is one fast resin! However it doesnt stop there. It has an unbelievably low viscosity of 40 mpas, thats about the same fluidity as milk!

WE NOW OFFER A SLOWER VERSION! The potlife on the slow version is now around 7 minutes, but the cure is extended as a result. However the final plastic is very strong. Use the slow version when pouring much thicker sections. Data for both products is below, just click the tech links! Safety Data identical for both products! Now supplied by the same manufacturer!

So for home hobby casters who dont have expensive degass and pressure casting systems in place, this may succeed where other resins and fast casts fail to eradicate air! That doesn't mean however that you can expect micron details to replicate faithfully without pressure casting!

We have customers who have managed to cure this product in sections of less than 1mm thickness! Warm the cured product up a little in thinner sections and you can form it with the heat, thicker sections will resist this. The product comes unfilled, so you the user can modify it or just use it as is. We recommend BL OG Calcium Carbonate as an impact resistance and resilience improver since its unlikely to affect viscosity that much. Looking to cheapen up your casts? Consider Fillite which works well with the product too.

Use this product in the new Viscolo range of rubbers without fear of it destroiying your mould in 20 pulls. We have reports of over 150 pulls from one mould!!

Kit pictured is a 2kg kit, but we supply this via the web in up to 10 kg kits, obviously the product picture is for reference only. Simply add 1-10 units to your cart to get the lower prices. eg 1unit we will supply a 1kg kit (500g+500g) and 5 units we will supply a 5kg kit (25kg+2.5kg)
