The Jiangong brand environmentally friendly one-component polyurethane waterproof coating produced by Xinjian Gong Waterproof Material Technology Co., Ltd. in Ningde City, Fujian Province is a reactive water-cured (moisture-cured) film-forming polymer waterproof coating. It is mainly based on polyether The raw materials are mixed with various additives such as latent curing agents and plasticizers and are produced through high-temperature dehydration and polymerization using a special process. When used, it is coated on the waterproof base layer. Through the chemical reaction between the end groups in the polyurethane prepolymer and the moisture in the air, a tough, soft and seamless rubber waterproof membrane is formed on the surface of the base layer. The technical indicators fully meet the B/"Polyurethane Waterproof Coating" standard. The research and development of this product has been included in the "Annual Science and Technology Project Plan" of the Fujian Provincial Department of Housing and Urban-Rural Development. 【Product Features】
●Single component, ready to use on site, easy to construct. There are no strict requirements on the moisture content of the base surface. It can be constructed on a humid base surface or under conditions of high relative humidity.
●Composed of pure polyurethane, it has high tensile strength, high elongation, good elasticity, high and low temperature resistance, and strong adaptability to shrinkage and cracking deformation of the base layer.
●One brushing can achieve a thick, dense coating without pinholes or bubbles. It has strong adhesion and does not need to apply base treatment agent on various base layers that meet the requirements.
●Chemical reaction forms a film that is resistant to long-term water erosion, corrosion, and mildew.
●Good environmental protection performance, using high boiling point solvent, no benzene solvent, no coal tar component, no solvent dilution on site.
●The color is adjustable and can meet the humanized requirements of different customers for surface color.
[Scope of application]
The product is widely used in waterproofing construction of various civil and industrial buildings such as roofs, basements, civil air defenses, toilets and baths, swimming pools, etc. It is especially suitable for underground projects and culverts with high relative humidity. used in the environment.
[Construction Technology]
●Basic base requirements: The base is smooth, free of sand, and free of debris. Uneven places and deformation joints and cracks in the base must be leveled with cement mortar. Pipe fittings, sanitary facilities and floor drains connected to the base must be strong, the joints must be tight, and the ends must be smooth, and no looseness is allowed.
●Coating construction: Generally requires three coats of scraping. After the first coat of coating is cured, apply the second coat. The scraping direction is perpendicular to the direction of the first coat of coating. The third coat of coating is applied on top of the film. If you need to use a rigid protective layer, in order to increase the bonding force between the waterproof layer and the rigid protective layer, before the coating film is completely cured, clean sand can be sparsely sprinkled on the surface. After the film is cured, the rigid protective layer is constructed.
Additional waterproof layer in details: Additional waterproof layer should be painted on details such as yin and yang corners, pipe roots, cracks and deformation joints.
According to the project requirements, the coating film construction can also be completed in one pass. After curing, the protective layer can be constructed.
●Ingredients and dosage: Stir evenly according to the construction dosage.
The reference dosage is: the dosage for thick coating film is about .3/.
[Notes]
●The construction site must maintain good ventilation, fireworks are strictly prohibited, and construction is not allowed in the open air on rainy or snowy days
●If the material has slight precipitation, it should be stirred evenly before use
●The paint should be opened immediately before use, and should be used up within minutes
●If the paint film is damaged at the construction site, use a cutter to dig around the break, then paint and repair it with waterproof paint .
【Packaging, Storage and Transportation】
●The products are tightly packed in iron barrels, kg/barrel, kg/barrel.
●During transportation and storage, avoid exposure to the sun and rain, do not approach fire sources, prevent collisions, pay attention to ventilation, and the storage temperature should not be higher than ℃.
●Under normal storage and transportation conditions, the storage period shall not be less than one month.
