PU 95 BINDER - 1

PRODUCT DATA SHEET – PU 95 BINDER I. CHEMICAL BASE / APPLICATIONS Single-component polyurethane which hardens with the humidity of the air. Polyurethane binder with permanent flexibility. Formula adapted to the creation of children’s playgrounds and to the laying of safety floors. Modified diphenylmethane diisocyanate (MDI) (8-9%) 0% TDI II. HARDENING The process starts at ambient temperature by a reaction with water vapour or with atmospheric humidity. A higher temperature and a high humidity rate shorten the setting time. Total hardening time is between 3 and 5 days. During the hardening, the temperature should not fall below + 10°C. III. APPLICATION For playgrounds and safety floors, the rubber granules must be mixed for at least 3 to 5 minutes in a suitable mixer. The end quality of the surface laid will also depend on the right choice of EPDM and SBR aggregate to be used. Non-compatible aggregate can affect or even prevent the drying process. You must therefore make sure that the rubber granules are fully compatible with the binder, that they are dry before use and have consistent particle size, i.e.: A low rate of dust The lowest possible percentage of fines Important note for the laying of playground surfaces: PU 95 consists of aromatic polyisocyanate the colour of which can be affected by light. The film is not therefore UV-resistant and can have an effect on the colour when using light-coloured EPDM granules. IV. RECOMMENDATIONS FOR USE A primer must be applied depending on the type and state of base. V. RISKS Can cause irritation by inhalation. VI. FIRST AID In the event of contact with the eyes: Rinse thoroughly with clean water while keeping eyes open. Consult a doctor (or a specialist) immediately. In the event of contact with the skin: Wash with soap and rinse thoroughly with clean water. In the event of ingestion: DO NOT provoke vomiting, consult a doctor immediately. If a high concentration of the product vapour is inhaled: If the person has difficulty breathing, consult a doctor immediately. Otherwise, cover the person well, take him/her out in the fresh air and then allow the person to rest. VII. FIRE PRECAUTIONS Models, drawings and names are registered.

Extinguishing equipment: CO², foam, dry powder. If the fire is large, spray with water. If the product is burning, fire fighters must wear a respirator (risks linked to carbon monoxide, nitric oxide and isocyanate vapours) VIII. MEASURES IN THE EVENT OF ACCIDENTAL RELEASE Cover with a damp material such as sand, sawdust, calcium-silicate-hydrate-based chemical binder. Transfer into a waste container after approximately 1 hour and do not close (formation of CO²!). Keep humid and exposed to the air in a safe place for 7 to 14 days. The waste can then be destroyed or disposed of in a special...

XII. STABILITY AND REACTIVITY Thermal decomposition: Polymerizes at approximately 230°C with evolution of the CO². Dangerous decomposition of the product: No dangerous decomposition of the products when they are correctly stored and handled. Dangerous reactions: Exothermic reaction with amines and alcohols. The product reacts to water by forming CO²; in closed recipients, risk of bursting due to the build-up of pressure. XIII. TOXICOLOGICAL INFORMATION EEC classification: HARMFUL XIV. SUMMARY This product is irritant for the airways. Repeated inhalation of the vapours at levels above the...
