| CASTALLOY is a series of fast, tough, low viscosity, very low cost, easy to use Liquid Molding Compounds. CASTALLOY has a short cycle time, providing a high volume of parts per day, ideal for both prototype and production runs. Fast turnover and very low cost are two key attributes of CASTALLOY. CASTALLOY has excellent physical properties such as: tensile strength, HDT, modulus of elasticity, etc. Parts can be de-molded in as little as 5 minutes! CASTALLOY can be used with silicone, epoxy, urethane, polyester, or aluminum molds. CASTALLOY is available in a creamy, off white color. Custom Coloring can be achieved by pigmenting CASTALLOY with Hapco’s easy to mix color dispersions. CASTALLOY fills the need for low cost, high performance parts in virtually any industry.&& |
