Mixing Instructions

MoldMaker may be mixed and dispensed using a plural component pumping machine for pour casting or RIM injection. It also may be dispensed using pneumatic cartridge guns with static mixer tubes or hand batch mixed in bucket using jiffy mixer. When hand mixing, stir slowly and carefully as to not induce air into resin mixture. Cured molding material produces a smooth glossy surface. Surface preparation of master plugs or forms is directly reflected to mold the surface. To obtain a Class A mold surface, mold surfaces must be polished smooth and free of pin holes. MoldMaker must be poured from bottom-up as to avoid air pocket trapping. For closed mold RIM, always provide adequate air-bleed tunnels or vents throughout mold perimeter. Just after the completion of liquid resin mold pour, small entrapped air bubbles may be relieved by quickly waving over the pour surface with propane torch. Please email our Technical Support Group for any questions regarding material, application or direction of use.
