UraGel 960 is a unique urethane polymer consisting of two thin liquids. After mixing, UraGel 960 immediately thickens to a buttery non-sag paste consistency, which forms a high build semi-rigid polymer when fully cured. UraGel 960 is easily shaped by sanding or milling and is especially well suited for thick spray applications to expanded polystyrene foam or other plastic or metal substrates. UraGel 960 is specifically formulated for application with simple hand held dual cartridge dispensing gun. The thixotropic (self-thickening) nature of UraGel 960 allows for easy application to difficult overhead and vertical surfaces. UraGel 960 contains no solvents or fumes thereby avoiding fire and worker health hazards in contained work environments.

Application and Mix Ratio

The one to one mix ratio, by volume of UraGel 960 insure ease of proper hand or machine mixing. Once mixed, UraGel 960 instantly self-thickens to a jell and remains trowable for 1 to 2 minutes.

Tough, rapid set, semi-rigid adhesive or gap filler
Before applying UraGel 960 to cut foam or other substrates, all surfaces must be clean and dust free insure total bonding. If possible apply UraGel 960 in a low humidity environment (below 70%) UraGel 960 gel consistency allows easy installation of plywood or plastic reinforces to high stress areas. Parts are full cure in 24 hours at 72˚F. Colder temperature will delay full cure.

Clean Up

Dispose of all empty UraGel 960 component containers in accordance with local, state and federal regulations. Empty component containers can be rendered non-hazardous by rinsing the containers with a small amount of mixed material and allowing the solvents to evaporate. The containers will then contain non-hazardous cured urethane.

Storage and Shelf Life

UraGel 960 is shipped from the factory in sealed containers. The containers should be stored in a cool, dry area that is protected from direct sunlight and moisture. Storage temperatures should not exceed 80°F. The shelf life of the factory sealed containers stored under these conditions is six months. Containers that have been opened should be resealed immediately after material has been removed in order to prevent solvent evaporation.
