They specialize in flexible mold making compounds, cold casting resins and associated products such as mold release. Flexible mold making compounds are made out of polyurethanes and silicone rubbers. These complaints are used to create molds for casting wax, epoxy, resin, plaster, gypsum and concrete materials. Both polyurethane and silicone have characteristics of flexibility, strength and ease of use.
Polyurethanes are less expensive but are less durable.
They can be blended to be as hard as inline skate wheels or as soft as latex. The silicones are the top of the line products, offering better shelf life and more durability for extensive casting of abrasive materials. They are also more expensive. This is much quicker than building up layer after layer of latex. There are even some mixes that can be sprayed through special equipment to set on contact.
