Product Description Product DescriptionSTWD189 one-component polyurea sealant is a moisture-curing polymer single-liquid type product with a new type of silane-sealed polyether as the main resin, which reacts with moisture in the air to generate a rubber-like elastomer to achieve the potting effect. Because of its high solid content, non-foaming, high bonding and hydrophilic reaction characteristics, the sealing effect of the product is better than ordinary similar products. At the same time, the product's low modulus and high elasticity make it effective in solving the leakage problems that occur in structures such as deformation joints, expansion joints and junction joints.Product Features and Advantages*Good durability, aging resistance, blister resistance, low temperature resistance, high temperature resistance *Curable in water*Certain strength and excellent elasticity, can be well adapted to deformation.*Dense internal structure of cured which can effectively waterproofing.*No air bubbles during moisture-curing*The curing is not sensitive to temperature, high temperature and low temperature can be cured.*Single-component material, simple and easy to apply*Solvent-free products, odorless, no VOCs.Product application scope Waterproofing and leakage reinforcement of roads, bridges and coal mines, waterproofing and sealing of expansion joints in buildings, and waterproofing and sealing of deformation joints and settlement joints in other buildings.Product informationItem Results AppearanceWhite Specific gravity (g/cm3) 1.1viscosity(cps)@25oC11000±1000Solid content (%) 98±2Surface dry time(min)30(25oC)Re-coat time (h)Min 6h; max 24h(25oC)Typical physical propertiesItem Test standardResults Hardness (shore A)GB/T 22446-200955Tensile strength, MPaGB/T 528-20091.5100% tensile modulusGB/T 528-20090.6300% tensile modulusGB/T 528-20091.0Elongation rate %GB/T 528-2009400%Adhesive strength (concrete base) MPa GB/T 22446-20091.3 (or substrate broken)Application tools and application instructionsHand scraper or pouring (loose concrete surface should be pre-treated and strengthened)Application environment Ambient temperature:-5~-+40oC.Relative humidity:≤90%Dew point:≥3oCSurface Pre-treatmentMetal surface: It is recommended to remove rust by sand blasting to reach Sa2.5 grade of ISO8501-1 or GB8923 standard.Concrete Surface: It should be solid, dense, flat, clean and dry. There should be no sanding, crusting, cracks, honeycomb surface and other phenomena.Please consult STWD technical personnel for application treatment of other materials.Application noteThis product can be used at a low temperature of -10oC. If used in a low temperature environment, it is recommended to place the paint bucket in an air-conditioned room at a high temperature for more than 24 hours.It is recommended to pour out as much as you can use up at one time, and seal the lid of the bucket in time, and the liquid shall not be poured back into the original bucket after use.When filling the gap, you can pour the material into a triangular plastic bag and tie it tightly. Apply on the sharp corners of the plastic bag to cut holes of 6-15mm in diameter, along the gap extrusion apply the material into the gap.If the application thickness is thick, it is recommended to apply 2 layer. Each application interval is in 6-30 hours.Corresponding curing timeSubstrate temperatureSurface drySolid dryFully cured +10oC40min24h7d+20oC30min15h7d+30oC20min10h7dNote: Curing times will vary depending on environmental conditions, especially temperature and relative humidity.Product packaging and shelf lifePacking specification 5kg/barrel; 10kg/barrelStorage temperature: 5oC-35oC*Shelf life: 6 months from the date of production and unopened state (ensure that the product packaging is sealed).*Store in a cool, ventilated environment, avoid direct sunlight.Product Health and Safety InformationFor information and advice on handling, storage and disposal of the product, please refer to the latest version of STWD's MSDS.
