Polytek Polygel® Spray 50 Liquid Rubbers
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Description: Polygel® Liquid Rubbers are without equal for making brush-on or sprayed blanket molds. Polygel products consist of two parts (A and B) that immediately thicken to a brushable or trowellable consistency after mixing. These non-sag products are especially useful for application to vertical or overhead surfaces. For brush-on application, use Polygel 35. In circumstances where spray application is best (e.g., large surface areas where brushing may be impractical), use Polygel Spray 35 or Spray 50. Polygel rubber molds are suitable for casting plaster, concrete and waxes, as well as limited casting with polyester, epoxy and polyurethane resins. Since Polygel products bond well to many surfaces, they can also be used as adhesives and sealants.

Product Line Features:

  • Easy 1:1 mix by weight or volume
  • Fast-- one-day brush-on or sprayed molds
  • Tough and strong
  • Color-coded mix indication
  • Good flow into fine detail
  • Good dimensional stability
