DTPU waterproofing coatingpolyurethane waterproof coating is made of isocyanate, polyether polyol as major raw material, with various additives and fillers by addition polymerization reaction. It is a kind of environmental protection type mono-component reactive polymer waterproof coating, it can react and consolidate with moisture to become elastic, tough and durable by coating evenly on the construction of the base surface with scraper, rollers and other tools. Accelerators can be used to accelerate the curing process, to improve the low-temperature film-forming property.
Product Description
Mono-component polyurethane waterproof coating is made of isocyanate, polyether polyol as major raw material, with various additives and fillers by addition polymerization reaction. It is a kind of environmental protection type mono-component reactive polymer waterproof coating, it can react and consolidate with moisture to become elastic, tough and durable by coating evenly on the construction of the base surface with scraper, rollers and other tools. Accelerators can be used to accelerate the curing process, to improve the low-temperature film-forming property.
1. Out of the box, liquid state, cold applied waterproofing, flexible, convenient;
2. High strength, elongation, flexibility; Dense coating, no bubbles, no pinholes;
3. Benzene solvent-free, non-coal tar ingredients, no pollution to the environment and human;
4. Strong bond(>1.5MPa), Primary treatment is not required In compliance with the requirements of the various substrates；
5. Chemical reaction film, Water resistance, corrosion resistance, no change, cold resistant, strong permeability;
6. Color is adjustable, can satisfy different customers different humanity on surface color requirements;
7. The viscosity is moderate(2500-4000mPa﹒S/23℃), can scratch, roller coating, spraying

Scope
1. Suitable for basement and bathroom, kitchen;
2. Waterproof and moisture proof for Water pools, cold storage, floor and other projects;
3. Waterproofing of underground works, municipal, bridges, dams and underground projects;
4. Non-exposed roofing Waterproofing
Key points of construction
1. Primary treatment and construction preparation:
Grass roots should be smooth, clean, solid, solid, no clear water, no sharp angles, no wet stains and make arc processing nodes; ensure construction tools must be dry and clean.
2. Detail additional layer node:
Yang angle, root canal, Deformation and other basic details, it should first conduct an additional waterproof layer construction, can be increased 2-4 times painted coating (thickness not less than 1mm)
3. Large area waterproof layer coating:
Coat the mixture by rubber or plastic scraper uniformly, required uniform thickness. Generally about 1.5mm, coating 2-3 times, once after brushing should be cured film after brushing and in different directions at last. The amount of approximately 1.5mm thick construction 2.4kg/m2.
4. Head and edge processing: increasing focus on closed-coated paint
5. Protective barrier:
Waterproof coating layer surface design requirements should be protected isolation layer construction
Construction Notes
1. Base surface of project should have clear water, or should be drained after 24h and then construction
2. Should be in the temperature more than 5℃ under construction, the construction site should be well ventilated and placed fire equipment.
3. After opening, should be used to finish as soon as possible, the time should not be more than 60 minutes; Remember longer directly exposed to the air, to prevent the crust. After opening the cover unused material must immediately be lid paint, will use up as soon as possible;
4. Before the paint is dry, it is strictly prohibited to walk on the waterproof layer, and pay attention to the protection of the construction site
Packaging, Storage and Transportation
1. Products stored in clean, dry, airtight CRC, the volume of 20kg / barrel, 25kg / barrel;
2. Transport in accordance with the requirements of dangerous goods, to prevent rain, exposure, extrusion, collision, ensure that the packaging intact;
3. Product should be stored in ventilated, dry, cool place, avoid direct sunlight and rain. Storage temperature should not exceed 40℃.
4. Under the condition of normal storage, shelf life is 6 months.
