Moulding and Casting

CASTING AND MOULDING RELATED PRODUCTS - Release Agents

Mould release will help to prevent the part sticking to the mould. Note that the mould release agent will have to be removed from the part before it can be painted.  Mould release agents are formulated for specific purposes, so ensure that you have selected the correct one for your application.

Ease Release 200
Ease Release 200 is an excellent general purpose release agent for making moulds and casting parts. This product will release polyurethane elastomers, epoxy resin, polyester resins, RTV silicones, rubber, and thermoplastic polymers. Ease Release 200 is effective on aluminum, chrome, RTV silicone, epoxy, rubber, and steel moulds.

Ease Release 2831
Ease Release 2831 is a wax-based non-silicone release agent. It has proven to be effective when used to release porous surfaces, such as polyurethane foams. Ease Release 2831 works with aluminum, steel and elastomeric mould construction.

PTFE NO.1 Aerosol
This is a multipurpose release not suited for epoxy with stand 300deg.(Teflon)

Universal Mold Release
Universal Mold Release is formulated especially for mould making and casting, and works well with most liquid rubber and liquid plastic products. It will release mould rubbers such as polyurethanes and polysulfides, from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modeling clays (containing water or sulfur) with Smooth-On Super Seal may be necessary. UMR also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber moulds. This product is not for use when moulding silicone rubber (use Easre Release 200) or casting urethane foam (use Ease Release 2831).

Release 870 Aerosol
870 is a wax in solvent phase, which is simply sprayed onto the mould. It  is  designed  for  casting  and  low  pressure  RIM  applications  up  to  100°C.  It  is  not  suited  to epoxy laminating resins.
