One-component polyurethane waterproof coating is isocyanates, polyether as the main raw material, with a variety of reactive additives made of flexible waterproof coating. The product has good physical properties, strong bond, often humid curing. First, the performance characteristics of one. Products with high strength, high elongation, high solid content, strong bond. 2. Natural leveling, good extension, to overcome the primary cracking caused leakage. 3. Normal construction, easy operation, non-toxic, weather resistance, excellent anti-aging properties. 4. Construction convenient, to overcome the shortcomings of the two-component polyurethane waterproof coating to be measured at stirring to ensure product quality stability and waterproof effect works. Second, the technical indicators: Standard (GB / T19250-2003) project tensile strength Ⅰ Ⅱ / MPa ≥ 1.9 2.45 Elongation /% ≥ 550 450 Tear Strength / (N / mm) ≥ 12 14 low bending resistance / ℃ ≤ -40 impermeability 0.3MPa 30min impervious solid content /% ≥ 80 dry time / h ≤ 12 Drying time / h ≤ 24 Third, the construction requirements 1. Requirements base surface smooth, clean, free from sand, loose. 2. Construction should be carried out based surface inspection to ensure compliance with the requirements, the first coat of primer, primer must be uniform. 3. After curing primer, a second brushing, brushing direction perpendicular to the previous one essential cross to prevent leakage scraping, brushing followed by three to five times. 4. Upon completion, the waterproof layer uncured not Exalted shall be carried out under the process, so as not to damage the waterproof layer. Fourth, transportation, storage 1. This product is stored in a dry, ventilated, cool place, shelf life from the date of manufacture unopened six months. 2. Transport of dangerous goods by non-processing.
