Polymer Modifiers for Concrete and Gypsum

Forton® 774 is the world-wide standard concrete additive for making lightweight GFRC panels. It is recognized by the PCI as the only polymer supported with a 20 year durability study. Matrix-C® polymer additive is a less expensive version. Alpha gypsum additives make gypsum far stronger and more weather resistant. Forton® and Matrix products are a lower cost alternative to resins. You can cast solid or make lightweight architectural and sculpture castings by reinforcing with glass fiber that are suitable for outdoor display. A variety of casting effects are possible including marble, metal, stone and more.
