Polygel® Spray 35 Rubber

SKU:
PGSPRAY35U80

Polygel® Spray 35 is a Shore A35, spray-on, polyurethane liquid mold rubber designed for making thin, stretchy, flexible molds of larger, complex originals. When low-viscosity Part A and Part B are mixed using a portable Plas-Pak sprayer or more sophisticated spray equipment, the mixture self-thickens to a creamy consistency ideal for quickly creating blanket or glove molds of complex objects. Polygel® Spray rubbers allow molds to be made in one application. For a self-thickening brush-on rubber for smaller mold making projects, consider Polygel® 35 Brush-On Rubber.

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
