Polygel 35 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.
