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.
