Thread Content

Spray-type polyurethane industrial coatings are characterized by their corrosion resistance and wear resistance. They also possess excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, and corrosion protection. 2. The formula can be adjusted as desired, ranging from soft rubber (Shore A30) to hard elastomers (Shore D90), allowing it to meet various operational requirements. 3. It has excellent corrosion resistance, capable of withstanding the erosion of acids, alkalis, oils, water, and other substances with a pH range of 3–11. 4. Excellent wear resistance: in submerged conditions, its wear resistance is 8 times that of cemented carbide steel, 7 times that of vulcanized rubber, and 3 times that of ultra-high molecular weight polyethylene. 5. It features high resistance to salt spray corrosion and good freeze resistance, allowing for normal operation over a wide temperature range of -57°C to 93°C. Special models can withstand high temperatures up to 170°C. Excellent adhesion performance: 1. Different primers and adhesives are used depending on the substrate; for all metal and non-metal substrates, there are suitable primers and adhesives available. 2. It has poor adhesion to silicone rubber and molecular weight polyethylene. Easy to construct: 1. Simple construction process, can be carried out at room temperature; insensitive to humidity and temperature, and causes no pollution. 2. Uses a complete set of equipment, enabling convenient construction and high efficiency ； The design thickness requirement can be achieved in a single construction step. 3. The series of spraying equipment meets the various requirements for the construction of different components. Environmental-friendly coating: 1. Two-component, 100% solid content, environmentally harmless, and free of any volatile organic compounds (VOCs). 2. Cures rapidly; no catalyst is required. It can be applied to any curved, inclined, or vertical surface without causing sagging. The gel time is short, with walking strength achieved within just a few dozen minutes. Aesthetic appearance: 1. Various colors and dyes can be added to create products in different colors; as a result, they remain clean and have an attractive appearance, without fading over time. 2. It has good prototype reproducibility; the coating is continuous and dense, free of seams or pinholes, offering an attractive and practical appearance, as well as excellent UV protection.
