Polyurethane RTV Liquid Mold Rubbers

MCPU-Series
Firm, Flexible Rubbers

DESCRIPTION: MCPU-Series Liquid Polyurethane Mold Rubbers consist of two parts (A and B), which, after mixing, cure at room temperature to flexible rubber. Molds made with MCPU-Series products are excellent for casting concrete, plaster and wax. In addition, when coated with a proper release agent, MCPU-Series molds can be used to cast various resins and foams. MCPU-Series Liquid Rubbers are formulated for good economy with high performance and durability.

MODEL PREPARATION: Porous models, such as wood, plaster, stone, pottery or masonry, must be sealed, then coated with a release agent. Multiple coats of paste wax dried and buffed will seal most surfaces. Potters soap can be used as a sealer for plaster. Lacquer, paint, PVA, and Release Agent also work well as sealers for many surfaces. Alternatively, a sealer and semi-permanent release agent, can be used on porous or non-porous models. Porous models must be vented from beneath to prevent trapped air from forming bubbles in the rubber.

Models made of sulfur-containing modeling clay (i.e., Roma Plastilina) should be sealed with shellac. [CAUTION: When shellac is used as the sealer, it must be horoughly coated with release agent because polyurethane rubbers bond tenaciously to shellac. In fact, uncoated shellac may be used to bond polyurethanes to certain surfaces.]

Non-porous models (i.e., metals, plasticene, wax, glazed ceramics, fiberglass, and polyurethanes) and sealed, porous models should be coated with Release Agent.
