SuperSafe Polyurethane Binder is used for manufacturing wet pour rubber surface installation. It is a single-component, MDI-based, non-volatile pre-polymer system. Polyurethane binder is primarily used to mix with EPDM and SBR granules for wet-pour rubber flooring installation.
Aromatic binder is the most commonly used PU binder because of its economic value and availability in the market. Aromatic binder tends to yellow upon exposure to sunlight or UV rays, this common phenomenon is called the “yellowing effect” of polyurethane binder. The yellowing effect may momentarily cause slight changes to the EPDM Granules of some colours until the yellowing tint layer wears off from foot traffic.
Soflex also offers Aromatic binder added with UV inhibitor for EPDM Colour Granules that are more sensitive to the yellowing effect. The added UV stabilizer acts as a retarder to delay the yellowing effect taking place, allowing the colour to change slower to a more uniform shade at an extended period of time.
