I. Introduction "Bolong" K11 waterproof coating series is designed for high potency different substrates waterproof material is acrylic polymer modified high-class cement-based waterproof coatings. The product is a dry powder (PartA) and liquid additives (PartB) matching, mixing occurs after the chemical reaction to form a tough flexible waterproof layer, the layer of the base surface with good adhesion, can close firmly with the formation of a permanent binding, and can inhibit the growth of mold and prevent pollution salty. Second, the main features of one, in the wet base surface can be construction, waterproof layer and high mechanical strength, good wear resistance. 2, coating to prevent moisture, salt contamination, inhibiting the growth of mold. 3, concrete still maintain breathability, this product is based on cement-based, waterproof layer can be directly paving tiles, mosaic and so on. 4, this product has a white, gray two kinds of appearance. Third, the scope: one for indoor and outdoor cement concrete structures, precast concrete structures, such as cement and brick walls wipe the bottom surface of the substrate. 2, Road underground parking, underground tunnels, water supply and drainage, floor wall floor. 3, the product non-toxic, can be directly used for drinking reservoirs, swimming pools, fish ponds and so on. 4, this product is also suitable for all kinds of positive side or the back surface of the water works. Fourth, the construction requirements: a grassroots must be clean, firm, smooth, dry, ash-free layer, can not afford to sand. 2, according to the proportion of the liquid into the container material prepared in advance, and then powder into the liquid feed in proportion to adequately stirring until liquid, powder and solvent. 3, using a roller, spray or brush the paste evenly stirring and a good brush or spray to cement-based surface coating 2-3 times better; coating thickness according to the design requirements of the construction. 4, the order of the coating after the first pass brushing brushing about 4h, coat dry and then in the direction perpendicular to 90 ℃ angle brushing 2 times, and so on. 5, after construction is completed within 24 hours ban stampede, to be completely dry solids do other cover layer (such as plastering, tiling, mosaic, etc.). Fifth, the technical indicators: Standard: JC / T894-2001 test item I Type II Type 1 Tensile strength MPa ≥1.2 ≥1.8 2 Elongation at break% ≥200 ≥80 3 impermeability 0.3 MPa, 30min impervious 0.3 MPa , 30min drying schedule impervious 4 h ≤4 ≤4 six dry time, packaging and storage: a liquid material shall be kept in shade above 5 ℃, the powder should be stored in a dry place. Pay attention to moisture, sun, rain. The product shelf life is one year. 2, the product liquid material for plastic drums, powder is lined with plastic bag packaging. 3, this product is 42kg / set (25 kg powder + 17㎏ liquid material). Seven, the reference amount and proportion: waterproof layer thickness 1.00㎜ when, with about 1.85㎏ / m (the total amount of powder + liquid material) Mixing ratio of 1 kg: 0.68㎏ Storage: Store in a cool dry place, unopened product can be Save for one year. Packing (double): I type: 25kg + 17kg powder additive (large component); 12kg powder + 8kg additive (the components); 5kg + 3.4kg powder additive (group copies) Type II: 25kg Powder + 13kg additives (large component); 12kg + 6.3kg powder additive (the component); 5kg + 2.6kg powder additive (group copies)
