| CGL-3 is specifically formulated to be used to make polyurethane “gel pads” encapsulated inflexible film or fabric casing using castor oil as its curing agent. Castor oil is commonly available, inexpensive, and renewable raw material. The users of this formulation have advantages from a low-cost common raw material to make price-competitive products. The formulation is made in such a way the user can change the mixing ratio to change the firmness/softness of the material. The hardness range covers most of the common gel-pad application such as shoe insoles, keyboard/mouse wrist rests, bicycle saddle covers, and surgical bed liners. The material can be manually processed at room temperature without use of an inline meter-dispensing machine. Thus, it does not require a large initial investment specifically to handle this formulation. A variety of polyurethane catalysts can be used for the optimum curing pattern for the application. The raw material component does not use a plasticizer and the blended resin is compatible with many polymer film materials for encapsulation. The component materials are relatively stable in a wide temperature range and easier to transport compared to other MDI-based products. The natural color of the cured material is opaque dark yellow, which can be pigmented with typical pigment dispersion paste colorants for various colors. System Code: CGL-3
