Northstar Polymers GK-7 Low Viscosity Polyurethane Gel Cast
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced

Material Notes: This material is formulated for production of thin polyurethane gel film or parts. The low viscosity property of the mixed component enables the user to cast this into a thin layer without entrapping a significant amount of air. This product can be cast in between films, molded in vertical mold, or cast on an open surface to make thin gel sheets. It is room-temperature-cure liquid castable system that can be processed without use of heat.

The suitable applications include custom gel sheets, tack pads, vibration dampening parts, and encapsulation of electric components. It is also suitable for many other custom applications where flexibility and some strength of the gel sheets or parts are required.

This material is not suitable for pouch filling application.
