Brushable Polyurethane Mold Rubbers
Polygel® mold rubber is without equal for brush-on blanket molds as they self-thicken to a thixotropic consistency when low viscosity Parts A & B are mixed. This rubber is non-sag and therefore especially useful for applications to vertical or overhead surfaces.
These unique polyurethane liquid mold rubbers, patented by Polytek, are high-performance, room temperature curing systems offering superior flexibility and toughness allowing durable molds to be made from relatively simple to the most highly detailed, undercut and complex models.
- Self-thickening formula
- Brushable or sprayable versions
- Easy one-to-one mix ratio by weight or volume
- Reproduces fine detail
- ornamental precast concrete casting
- architectural GFRC casting and restoration
- plaster casting
- art foundries
- sculpture and décor reproduction
- numerous hobby, craft, prop and display mold making and casting projects where brushable molds are required
- View more applications in the Polygel product photo gallery.
Sprayable Polygel rubbers are ideal for large surface area applications where brushing is impractical.
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.
