H2001 Waterborne polyurethane hammertone paint
Product introduction
The special imported water-based trapezium, the national chemical science, deionized water, water-based additives and environmental protection filler and other components, does not contain benzene, a family, second-grade benzene and other organic solvents.The product is prepared by using water-based aliphatic polyurethane resin as film forming base material, HDI as curing agent, adding environmentally friendly fillers and functional auxiliars. Full film, high gloss, bright color. Good adhesion, high hardness, excellent weather resistance.
This product is a water-based system, not suitable for low temperature environment, the temperature below 10℃ is not recommended for construction, the product below 0℃ will freeze, can not be used.
Product Application
Suitable for high surface requirements, high weather resistance requirements of the top paint coating. It is mainly used in the surface decoration of metal components such as wind power tower barrel, mechanical equipment, construction machinery, petrochemical oil pipe, etc. It has very excellent outdoor weather resistance and corrosion resistance.

Main characteristics
In order to achieve the maximum film thickness of a single coating, the use of high-pressure airless spraying is the best means, if other spraying methods are used, it is difficult to obtain the required film thickness. When using ordinary air spraying, it may be necessary to cross paint several times to obtain the maximum film thickness.
The use of this product with primer can reflect the anti-corrosion performance, it is not recommended to use alone directly coated on the surface of steel, during the coating process or just after the coating surface will occur water vapor condensation, will make the surface tarnish, film quality deteriorates.
The gloss and surface finish depends on the coating method, so it is possible to avoid mixing multiple coating methods, and the traditional air spraying method can be used to obtain the best shine and appearance.
When not fully cured, touching water will cause discoloration, especially dark color.
Advantages
1.Longer paint intervals
2.Excellent water and salt water resistance
3.The film is tough, strong and wear-resistant
4.Thick paste heavy anticorrosive paint
5.Good compatibility with a variety of subsequent coatings

Storage and transportation
1. The product should be sealed and stored in a dry and well-ventilated warehouse with a storage temperature above 5 ° C and below 35 ° C to prevent direct exposure to water and sunlight, isolate the fire source, and stay away from the heat source.
2. If the product meets the storage conditions, the storage period is one year from the date of production, and the storage period can be tested beyond the storage period. If it meets the standards, it can still be used.
3. During the transportation process, the product should be prevented from cold, rain and sunlight exposure, and should comply with the relevant provisions of the transportation department.
Surface treatment
1. The surface must be clean and dry, and the surface treatment of the substrate must meet the requirements.
2. The tools used in the construction must be dry and clean.
3. it is forbidden to contact with acid and alkali during the process of paint preparation and coating.
4. the painting interval must be strictly controlled, when the temperature is 25'C, the painting interval shall not be less than 12 hours.
5. Can not paint thick, a film can not exceed 40μm or will bubble.
6. Construction and drying and curing during the relative humidity is not greater than 75%, the temperature can not be less than 0 ℃ , otherwise the film can not be completely cured influence.
When painted directly on the surface of Yu material, the substrate should be polished, requiring clean, dry, no rust, no oil stains, etc. When painted on the bottom surface, the primer surface is required to be clean, dry and free of dirt.Remove the oil, dust and other dirt from the front paint mirror, and no acid or water condensation on the paint film.
For the topcoat that has been cured for a long time, the paint film must be polished with sandpaper before the subsequent topcoat can be applied.
The lacquer film must be dry.
Temperature of the substrate The temperature of the substrate should be 3'C above the dew point.
Notes
1. The two-component product shall be mixed evenly in strict accordance with the proportion provided in the product manual before construction.
2. All construction tools, equipment and pipelines must be cleaned to avoid reactions between different paints and clogging equipment or paint pipelines.
3. The mixed paint must be used within the time specified in the construction applicable period. If the product exceeds the applicable period, the construction performance and coating performance will be affected.
