3 SDS-4 Dust Suppressant (Evaluation Product)

3 SDS-4 Long Term Dust Suppressant Technical Data Sheet

1. PRODUCT DESCRIPTION 4. MIXING INSTRUCTIONS 3M™ SDS-4 Long Term Dust Suppressant is a patented, It is recommended that SDS 4 is added directly from the pail concentrated water management tool, for use wherever to the water vessel. To avoid excessive foaming, SDS 4 dust suppression is required, such as: should be added to the water vessel after the water has been loaded. The product self mixes during normal truck  Mine Haul Roads, windrows and stockpiles movements.  Construction Sites and major works  Unsealed roads and parking areas 5. APPLICATION LEVELS A recommended dilution rate of 0.2% means a 20 kg pail of  Unsealed airports and sporting grounds product is added to 10,000 litres of water, which should be applied at a recommended maximum coverage of 0.5 litres SDS 4 is a water suspension consisting of an per square metre per application pass. agglomerating polymer and a wetting agent. The wetting agent is designed to accelerate water penetration and Initial application should be 6-8 passes on the first day, increase water retention of the road surface. The allowing liquid to be absorbed between passes. This allows a agglomerating polymer is incorporated to bind the road rapid buildup of moisture in the soil. It is not necessary to fines together into larger particles, which has a twofold stop traffic in this period; however care should be taken to benefit. Firstly, the particle size is increased, with larger avoid applying excessive liquid at corners. Traffic use after particles being less prone to become airborne dust. application will assist penetration of the product. Secondly, the retention of roadway fines is increased, which has been demonstrated to reduce the degradation For days 2-3, 3-4 passes should be made each day, reducing rate and maintenance cycle for unsealed roads. to 1 pass per day or as appropriate for the conditions. SDS 4, when used according to instructions, enables a For areas that do not have traffic use to increase penetration, reduction in water consumed for dust suppression and are prone to high levels of wind, such as stockpiles, it is purposes. Repeated applications have a cumulative effect, recommended that SDS 4 is applied at 0.5% dilution. maintaining subsoil moisture content for long periods depending on soil types, traffic and weather conditions. Different application rates and dilution levels may be required for a high temperature or windy environment, according to the Advantages of using 3M™ SDS-4 Long Term Dust conditions at individual sites.
