RTV SILICONE RUBBER

Cast-A-Mold 25T is a general purpose rtv silicone elastomer which exhibits excellent tear strength, long library life, and accurate detail reproduction. Cast-A-Mold 25T is a condensation cured silicone (tin catalyzed ) It is used to make rubber molds that can be used to cast polyurethanes, epoxy's, polyester's, cement, concrete, soap, wax, plaster, etc.. It is easy to mix and de-air, and will cure at room temperature over virtually any surface. Cast-A-Mold 25T is extremely useful for applications where superior physical properties are required.

Cast-a-Mold thixotropic additive is specifically formulated for brush on molding. After mixing the thixotropic additive 1-3% by weight into the Cast-A-Mold silicone rubber the material will thicken to a creamy paste that can be easily  brushed on vertical or overhead surfaces without sagging or running. A thin layer of non-thixotropic silicone should be applied first to capture detail and achieve a bubble free surface.

Cast-a-Mold silicone thinner is a dimethyl fluid with a viscosity of 50 cps. This thinner will be compatible with any of our silicone rubbers. Lowering the viscosity of a mold making rubber will allow the silicone to flow more easily into smaller detailed areas. We recommend only adding 3% to 5%. Adding too much silicone fluid can adversely effect the physical properties of the silicone itself. Tear and tensile strength will be lowered if too much silicone thinner is used. The thinner can also be used to help replenish the life of a silicone mold. We recommend brushing a small amount into the mold before storage.

Mold-Dough 25P is a two component silicone putty that is easy to use, odorless, and non-toxic. It is ideal for a wide range of molding applications which include: making impressions, hobby/art projects, model-making, special effects, rapid prototyping, mold making, etc.. Mold-Dough is very easy to use just take equal amounts of side "a" and side "b" and knead together until you get a uniformed color then press the object wanted molded into it. Mold-Dough has a 4 minute working time and 30 minute demold time. This is ideal for professional model makers, hobbists, crafters, and taxidermists. Mold-Dough works excellent with polyurethane, epoxy, and polyester casting resins.

Note: Mold-Dough is a addition cure (platinum catalyzed) system. As such, it can be heat accerlerated and is subject to inhibition/poisoning by the usual factors which include (but are not limited to) sulfur, sulfur based clay, sulfur compounds, and amines.
