Poly 75-70 Liquid Rubber
Poly 75-70 is used primarily for making tough, durable molds, form liners and stamps for casting, forming and texturing concrete. Molds are also often used to cast plaster, wax, and limited resins and foams with the proper release agents. Common cast products include decorative concrete countertops, precast architectural panels, sound barriers, fences, pavers, slabs, patio stones, retaining wall blocks and for virtually all other types of cast stone and GFRC applications.
This rubber has high abrasion resistance and long mold life for high volume casting operations.
