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

Gaskets for low pressure tanks and containments

Vibration dampening, noise reduction, bumpers, and padding products

Encapsulation material for electronic components

Prototyping and short run productions

Softer Range Room Temperature Curable Systems

The following casting resin systems are specially formulated to service low-A Durometer hardness range. The material retains flexibility even at a cold operation temperature, and it is stable for a long period of time in an aqueous environment.  The recommended applications include gaskets used in low temperature at low pressure, mold-making for concrete and low-temperature-curing resins.  The components for these formulas are less moisture sensitive than the general purpose formulas for ease of use.   Pot-lives for these formulations are relatively long to allow wide working time.  The mixing ratios are made to be easy one-to-one or one-to-two ratio for ease of handling.
