One. Corrosion resistance
In addition to hydrogen acid, concentrated nitric acid and some strong oxidants, polyurea coatings show good stability in acid, alkali, salt, seawater, oil and other media, in the salt spray medium to do a strengthening comparative experiment, 1000 hours later, polyurea and its coated No. 20 steel plate has no change, polyurea in the steel plate adhesion has no change, and the corresponding test block rot thickness up to 4mm, the experiment fully proves the polyurea coating to the marine atmosphere resistance.
Two. Weather resistance
Polyurea coating can be used for a long time under harsh conditions, UV resistance, cold and heat shock, wind, frost, rain and snow, long-term outdoor use without pulverization, cracking, and non-shedding, aging experiments show that the weather resistance life is more than 50 years, in Antarctica, the Sahara Desert and South American rainforests, etc., the application practice under various climatic conditions proves this.
Three. Service temperature
Polyurea coating can be used for a long time in the temperature range of -50°C~100°C, and can withstand short-term thermal shock of 150°C.
Four. Adjustable performance
Through different formulas, component molecular weights, branching degrees and additives, adjust the physical properties of the material to meet the requirements of different uses, different branch number and branch length of the prepolymer, the hardness of the coating can be adjusted from soft rubber to hard elastic nature, arbitrary adjustment, colleagues adjust the wear resistance and other mechanical properties, add short glass fiber, etc., to enhance the material, appropriate additives can further enhance the wear resistance, add various pigments, and make a colorful product surface.
Five. Mechanical properties
Polyurea waterproof material has good adhesion to all kinds of substrates, and in the concrete adhesion test, it is always the concrete body failure rather than the joint surface failure, the wear resistance of the wear-resistant coating is 10 times that of ordinary carbon steel, and the tensile strength, flexibility, wear resistance and flame retardancy of the coating are outstanding.
Six. Constructability
Unlike polyurethane or epoxy resins, polyurea is hydrophobic, insensitive to moisture, moisture, and is not affected by cold surface stool, nor is it affected by ambient temperature and humidity. It can be applied in a cold environment of -28°C and cures normally. Extremely adaptable, can even be sprayed directly on water or ice, even at -40 °C, it almost does not affect the surface drying time, fast curing, can be continuously sprayed on any curved surface, vertical surface and top surface, no sagging phenomenon, 5 seconds of gel, one minute can be moved or stepped on, the thickness of a molding is not limited, overcoming the disadvantages of multi-layer construction, the original shape reproducibility is good, no seams, beautiful and practical. Polyurea is sprayed with a two-component without a catalyst. 100% solid content, no volatile or toxic substances, environmentally friendly, the use of complete sets of equipment, convenient construction, high efficiency.

1. Increase efficiencyThere's a reason operators don't like manual mixing. It's a repetitive, physically demanding, and inefficient job. This includes manual heating and mixing of elements, trying to guess the correct dosage and loading the mixed paint into the spray system. It's becoming increasing
The moon is very bright at the fifteenth day of the month, and the love is even stronger at the Mid-Autumn Festival; the Mid-Autumn Moon is the most round in a year, and the osmanthus rabbit is accompanied by Chang'e; the warmest thing on earth is the reunion, and we are looking forward to the night
On August 30th, Shandong Hightop Group went to Jining Children's Welfare Institution to carry out a donation activity of “Drops converge to become the sea of love and brighten the future”, and sent a batch of love materials to the children.In order to provide the most accurate care for the children,
What is a two-component sprayer?Two-component sprayer refers to the A/B component coatings, when spraying construction fusion spraying operation, or the main liquid material with the curing agent in the spraying construction according to a certain ratio of mixing spray, to achieve the best coating e
In the early 1970's Germany will custom polyurethane two-component liquid reaction molding technology, that is, RIM-PU technology commercialization to really promote the development of the custom polyurethane industry. Two-component rigid polyurethane liquid reaction molding process coup the traditi
The advantages of polyurea spraying equipment over manual hand brush construction:First, extremely high coating efficiency. Spraying efficiency is as high as 200-300 square meters per hour, more than 10 times that of traditional roller construction.Second, excellent surface quality. Spray coating is
As we all know, polyurethane is a widely used polymer material on the market, which can be used as adhesives, sealants, coatings, insulating materials, fillers, foaming materials, engineering plastics, rubber products, fibers and so on.And polyurea waterproof coating has gradually become familiar to
