ORIGINAL UNFILLED

PART A is a black liquid and PART B is a clear liquid that react to form a black plastic. It has the strongest physical prosperities, most heat resistance and the lowest viscosity similar to water. The cure is gradual making the resin suitable for roto casting where the mould is slowly rotated as the resin cures to form hollow objects. It doesn’t contain the filler that neutralizes Co2 gas created when the moisture in the air introduced when mixing reacts with the resin which can in certain circumstances form tiny bubbles.

ORIGINAL FILLED

PART A is a black liquid and PART B is a clear liquid that react to form a black plastic. Similar to the Low Odour resin but has marginally stronger physical properties, lower viscosity and faster de-mould time. The cure is gradual making the resin suitable for roto casting where the mould is slowly rotated as the resin cures to form hollow objects. Contains a filler that helps minimize bubbles by absorbing Co2 gas produced when moisture in the air introduced when mixing the two parts reacts with the resin.

LOW ODOUR

PART A is a black liquid and PART B is a dark amber liquid that react to form a black plastic. Similar properties to the Original Filled resin but has a different formula to give a low odour. The cure profile makes the resin unsuitable for roto casting. Contains a filler that helps minimize bubbles by absorbing Co2 gas produced when moisture in the air introduced when mixing the two parts reacts with the resin.

FILLITE FILLER

Lightweight, hollow, spherical, low density, free-flowing, alumino-silicate microspheres which when added at 50% of the weight of the resin will increase the volume of the resin by 100-150% and remain pourable.

FUMED SILICA FILLER

Thixotropic additive, when added to the resin at 5% creates a paste that can be brushed or spread into or on to moulds to create hollow casts.

METAL FILLERS FOR COLD CASTING

An initial layer of a resin and metal filler mix are applied to the surface of the mould then the mould can be back filled with non metal filled resin. Once cured the cast piece is carefully polished with fine wire wool to bring out the finish of the metal. The higher the ratio of metal filler to resin used the higher the quality of the finish.
A more efficient method if using a silicone mould is to cover the surface of the mould in the powder, turn over and tap. A thin layer will stick to the surface and the excess will fall off which can be collected and used again.  Very gently pour in the resin being careful not to disturb the powder. The resin will soak into the powder leaving a very thin dense layer of metal on the surface of the cast that can then be polished.
