Pathway Polymers® Por-A-Mold Low Viscosity Polyurethane Mold Materials
All POR-A-MOLD molding products from Bare-Metal Foil give the benefits of minimum shrinkage with dimensional integrity, can be hand or machine mixed, poured, sprayed or brushed, and, when used according to instructions, are relatively safe to use. All are two component molding products that are mixed 1:1 by volume and are excellent at capturing fine detail. Because these products are polyurethane rubbers they require a release agent when using Por-A-Kast resin. Por-A-Mold S series polyurethane rubber comes in a pourable form which is listed at the top of this page. Or a trowable form that is listed toward the bottom. Easy releasing molds for casting gypsum, concrete stamping, concrete castings, plaster, candle wax, bronze casting.

POR-A-MOLD S-111, S-333, and S-555
These are pourable molding products that are recommended for molding small objects. S-111 is soft and supple and is excellent for molding deep undercuts and has great elasticity needed to unmold successfully, yet transfer the deep undercuts to the casting. S-333 is medium hardness and is intended for molding objects with moderate undercuts. S-555 is firmer yet and is intended for objects with light to moderate undercuts, yet has the strength to be used over and over while resisting distortion.
