Polygel® Brush-On 35 Rubber

Polygel® 35 is a self-thickening, brush-on polyurethane liquid mold rubber designed for making thin, stretchy brushed molds. When Part A & Part B are mixed together, the rubber self-thickens to a creamy consistency ideal for making molds on vertical and overhead surfaces. Mold makers often apply the first layer of Polygel® 35 without any additional thickener and then add PolyFiber II Thickeners to subsequent layers. A sprayable version of Polygel® is also available in a Shore A35 hardness (Polygel® Spray 35)

WARNING: This product can expose you to chemicals including Toluene diisocyanate (TDI), which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.
