Polyurethane waterproof coating. Non-tar polyurethane waterproof coating non-tar-component polyurethane waterproof coating system polyurethane waterproof coating material advantages, the use of water as chain extender polyurethane waterproof coating to avoid the amine chain extender toxicity oil-based polyurethane waterproof coating, forming a flexible after curing seamless rubber waterproof layer. I. Features: 1. Construction at room temperature, easy to operate, non-toxic and harmless. 2. Natural leveling, good extension, overcome the grassroots cracking caused leakage. 3. Has excellent weather resistance, oil resistance, water resistance, corrosion resistance. 4. May damp construction (no clear water), strong adhesion to shorten the construction period. The first layer coating: After polyurethane A, B groups were and xylene by 1:l.5:0.2 ratio (weight ratio) fit into the bucket spices, mix well with an electric mixer (about 5min ), using a rubber scraper knife coating a layer of paint or paint brush, the thickness to be uniform, blade coating amount of 0.8 ~ 1.0kg / m preferably, back from the inside out with the operation. The second layer of film: After the first layer of the coating, the coating cured to a tack-free, according to the first pass material ratio method, the second time the operation polyurethane waterproof coating paint company, as the coating thickness, Scratch the direction perpendicular to the direction must first pass Scratch, scratch the same amount and the first pass. Polyurethane waterproof coating purposes, Anhui polyurethane waterproof coating, long a source of waterproof material provided by the Weifang City for the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the long-source waterproof material into the brilliant and you work for a better future!
