Polygel® 35 Brush-On Rubber

brushable-polyurethane-mold-rubbersPolygel® 35 is a Shore A35, 1A:1B mix, 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 blanket or glove molds of complex objects. Great for casting plaster, concrete, as well as resins and foams with suitable releases.

NOTE ON FOUNDRY WAXES: Certain foundry waxes can cause excessive oiling in Polygel rubbers; this is the case when liquid Polygel is applied to the foundry wax and when the foundry wax is poured into cured Polygel molds. Perform a small test cure to ensure compatibility.
