Polyurethane binder PU BINDER 1118

EPDMpolymer-basedfor flooring

POLYURETHANE BINDER 100% solids, aromatic, polyisocyanate-prepolymer, moisture-curing binder based on diphenylmethane diisocyanate. It is MDI based and solvent free and has low viscosity. It exhibits excellent adhesion to all rubber granules and gives a strong performance both in terms of tensile strength and durability. It is mixed with RECYCLED RUBBER 858 or EPDM 856 granules for the creation of the elastic safety flooring SAFEPOL MULTICOLOR or other flexible rubber floorings, ideal for playgrounds, athletic tracks, schools etc. Combines and bonds RIM components, polyurethane granules and sponge particles. Also it can be used as lining for insulation and for pasting. Density of mixture (25°C): app. 1.08 – 1.18 Kg/Lt Viscosity (25°C): 4.000 - 8.000 mPa.s Pot-life (25°C): 30-75 min. Application temperature: Min 10°C Curing (25°C and %60 relative humidity): After 24 hours it cures. Applied on dry surfaces without rising humidity issues, free of materials that might prevent bonding e.g. dust, loose particles, grease etc (in case of asphalt or concrete). The success in the application depends on the right preparation of the underlay and use of the material. Good, dry cleaning of the surface from dust and residues using vacuum cleaner and squeegees. Can be used for kids playground, running tracks, sports grounds, walkways and offices. Moulded in production: Rubber granules and binder are thoroughly mixed, taken into moulds,and then pressure is applied. 160 bar pressure, mold temperature of 130 degree gives reasonable results in 12 - 15 minutes. In molding applications, binder content should not fall below 5%.
