MOLDMAKING

Silicone moldmaking materials are used extensively to create molds that will produce exact replicas of picture frames, statues and furniture. Whether you are casting polyurethane foam, polyester or low melt alloys like bronze you can count on QSi moldmaking silicones to deliver exact replicas time after time. Silicone moldmaking products consist of two components. A liquid base and a catalyst or curing compound. Tin curing silicones give you a wide range of softness, viscosities and curing speeds to choose from, while platinum curing products offer less shrinkage and heat accelerated curing. QSi has a broad range of silicone tin and platinum curing moldmaking products that can handle just about any moldmaking application.
