Product Description Product DescriptionSTWD952 is a single component aromatic polyurea waterproof anti-corrosion protective coating material, it has excellent adhesion force with various substrate. Due to its unique chemical structure, the product not only has excellent resistance to chemical corrosion medium, but also with excellent elasticity, high strength, abrasion resistance, impact resistance, scratch resistance and other physical properties.Product features and advantages*High solids, low VOC emissions *Easy to apply, brush, roller, air spray or airless spray all suitable.*High physical properties of wearable, impact resistance and scratch resistance*Excellent waterproof performance*Excellent chemical resistance, can withstand certain concentration of acid, alkali, salt, oil, organic solvents etc.*Excellent adhesion force, fast bonding well on the surface of steel, concrete, wood, fiberglass and other substrates.*Wide temperature requirements, can be used in environment of -50 oC ~ 120oC.*One component material, easy operation without ratio mixed, reducing labor costsTypical use Anticorrosion waterproof protection of petroleum, chemical, transportation, construction, electricity, container and other industries. Maintenance of bridges, waterproof anticorrosion of tunnels, waterproofing protection of industrial floor, sewage water treatment pool, building roofing, water conservancy dam, hydropower station buildings.Products informationItemResultsAppearanceColor adjustableSpecific gravity (g/m3)1.2Viscosity (cps)@20oC420Solid content (%)75 (vary with different colors)Dry time(hour)1.5-2 Pot life (h)1Theoretical Coverage0.15kg/m2 (thickness 100um)Physical properties ItemTest standardResultHardness (Shore A)ASTM D-224082Elongation (%)ASTM D-412400Tensile strength(Mpa)ASTM D-41224Tear strength (kN/m)ASTM D-62465Wear resistance (750g/500r)/mgHG/T 3831-200610Adhesive strength (Mpa), metal baseHG/T 3831-200610Adhesive strength (Mpa), concrete baseHG/T 3831-20063.2Impact resistance(kg.m)GB/T23446-20091.0Density(g/cm3)GB/T 6750-20071.2Chemical resistanceAcid resistance 30%H2SO4 or 10%HCI,30dNo rust, no bubbles, no peel offAlkali resistance 30% NaOH, 30dNo rust, no bubbles, no peel offSalt resistance 30g/L,30dNo rust, no bubbles, no peel offSalt spray resistance, 2000hNo rust, no bubbles, no peel offOil resistance 0# die sel, 30dNo rust, no bubbles, no peel off(For reference: pay attention to the influence of ventilation, splash and spillage. Independent immersion testing is recommended if requires other specific data.) Application environmentRelative temperature: -5~-+35oCRelative humidity: RH%:35-85%Dew point: the temperature of metal surface must have 3oC than dew point.Application tipsRecommended dft: 100-200 (as design requirement)Re-coating interval: 4-24h, if the interval time exceed 24h or has dust deposited, sand-blasting first and clean well prior to application.Coating method: airless spray, air spray, brush, rollerApplication noteIt can be applied in the low temperature below 5oC. Put the coating drums into the air-conditioning room for over 24 hours when apply in the low temperature environment.STWD recommends to agitate the coating uniform prior to application, pour accurate quantity of material to another vessel and seal well immediately. Don't pour the rest liquid to the original bucket.The viscosity of product is set up in the factory, thinner shall not be random added by the applicators. Call the manufacturer for instructions of special thinner if the viscosity changed as the application environment and humidity.Curing timeSubstrate temperatureSurface dry timeFoot trafficSolid dry+10oC6h24h7d+20oC3h12h6d+30oC2h8h5dShelf Life * storage temperature: 5oC~32oC* shelf life: 10 months (sealed)* store in cool and ventilated place, avoid direct sunshine, keep away from heat* package: 5kg/bucket, 20kg/bucket, 25kg/bucketProduct health and safety information For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the latest Material Safety Data Sheet containing physical, ecological, toxicological and other safety related data.Integrity declaration STWD guarantee all technical data stated in this sheet are based on laboratory tests.
