Room Temperature Curable Casting Systems
Solid/Non-Foam Casting Resins
Because of the low-cost mold and simple molding process, using this type of material requires a relatively smaller initial investment to start a production. The materials cure at room temperature; thus, very often, the initial tooling and equipment cost can be very low. Some of the existing applications are:
Concrete molds and patterns
Vibration dampening, noise reduction, bumpers, and padding products
Encapsulation material for electronic components
Prototyping and small runs of products
