Poly 75-75 Liquid Rubber
Poly 75-75 is a 2A:1B mix ratio, liquid polyurethane rubber. It is often used to make firm, durable molds, liners, and stamping and texture mats for forming and texturing concrete. These molds feature high tensile strength, tear strength, and elongation.
Typical applications include the making of concrete retaining wall blocks, sound barriers, architectural panels, decorative countertops, fences, slabs, pavers, and more.
Poly 75-75 molds can also be used to cast plaster, wax, and limited resins and foams with the proper release agents. This rubber has high abrasion resistance and long mold life for high volume casting operations.
