Resin Casting & Silicone Mould Making Kit XL

£69.01 inc. VAT

380 Moulding Rubber, G26 Resin, Release Agent and accessories for making reusable silicone moulds and creating resin copies of parts



The SylCreate Casting Kit XL contains all the products and accessories needed to take high-quality reusable silicone moulds of items, which are then used to cast multiple detailed copies of the original part from polyurethane casting resin.

Scale model makers use the Casting Kit to create resin copies of masters they have sculpted from epoxy putty or kit parts which have been modified. Resin artists use the Kit to copy items from original work, including pieces of jewellery, figurines and other artefacts.

The Casting Kit can be used by industrial users to copy machine parts, avoiding repetitive tasks when making prototypes or new components.

All the products are easy to use and the Kit contains a full set of step-by-step instructions. On our Showcase section, we have produced a video showing how to make and use a two-part silicone mould for resin casting.

The simple process involves using 380 Silicone Moulding Rubber to take a mould of the original item. 380 Rubber creates flexible, detailed moulds with high tear strength.

Moulds have low shrinkage with no distortion and good dimensional stability. Depending on the size and complexity of the part being copied, moulds are reusable up to 20 times.

The Kit also contains Mould Release Agent for making two-part moulds. Release Agent is coated onto the first half of the silicone mould to prevent the two parts sticking to each other.

Polycast G26 Polyurethane Casting Resin is then poured into the mould to make the copied part. G26 has low shrinkage, does not sag or distort with heat and cures to a light beige colour. Oil-based or dry pigments can be added by the user to colour the resin. .

It has a pot life of 3 to 4 minutes and casts fine parts, picking out detail well. Numerous reproductions can be made relatively quickly using G26.

In addition to Moulding Rubber, Casting Resin and Release Agent, the Kit comes with a range of accessories to help with the silicone moulding and resin casting process.

Can I use pigments to colour my resin?
Yes. Both oil-based and dry pigments should be fine for colouring resins. We recommend that you mix a small amount of resin with your pigments first to test the compatibility. Water-based pigments should not be used.
