Urethane Plastics
Quickcast (Roto-Cast)
Quickcast A/B 100% solid Castable Urethane Plastic, two component system. It’s low viscosity, low shrink, good impact resistance and quick demolding cycle lends itself well for a variety of casting applications, especially for roto-casted parts. Once cured, it can be machined, sanded and drilled. Material can either be hand or meter mixed. Fillers can be added to adjust cost, appearance and function--See Filler Product Tech Sheet for more information. Applications include art reproductions, model kits, stage props, prototype pieces, production parts, roto-casting, any application where durable plastic parts are needed.

Processing Instructions:
Blend components "A" and "B" at the specified ratio with mixing stick for about 12 to 15 seconds. Do not use high shear mixers unless mixture contains filler. Pour immediately into the mold--if mold is non-silicone, use appropriate release agent. Do not disturb the mold until part is ready to be de-molded. Pressurize mold to aid in air release when needed. Painting or coating operations can be performed when material is fully cured 24-72 hours at 75F. Post cure at 100F for several hours can speed up cycle after 24 hours room temperature cure. Wash the surface to be painted with grease devolving soap or mineral spirits before painting. Off ratio can cause oily surfaces, which will limit paint adhesion. Please pre-test all coatings.
Storage/Shelf Life: 6 months
Components must be stored in their original, unopened containers at temperatures between 75F and 85F. Shelf life of materials when kept in unopened sealed containers, at the recommended storage conditions, is six months. Containers should not be opened until ready for immediate use. To avoid air entrapment, undue agitation of containers should be avoided.
