This repair agent adopts polyurethane resin as the base material, mixed with bronze powder as the wear-resistant filler, which has excellent wear resistance and lubricating performance. It can form a smooth and wear-resistant coating on the surface of the worn hydraulic cylinder rod, which can effectively reduce the friction between the hydraulic cylinder and the seal, and avoid leakage caused by wear. It has excellent adhesion to metal substrates, and the adhesion strength can reach ASTM D3359 Level 5B, which will not fall off during long-term use. It can be cured at room temperature, and the construction is simple, only need to clean the worn surface, apply the repair agent and polish after curing. It has excellent oil resistance, and can withstand long-term immersion in hydraulic oil without swelling or peeling. It solves the pain points of traditional hydraulic cylinder repair methods, such as high cost, long downtime and poor repair effect.
Each set contains 400g of repair agent, including 300g of component A (repair paste) and 100g of component B (curing agent). The repair layer thickness can be adjusted from 0.2mm to 2mm according to the wear degree. The wear hardness reaches HRC 60±2, which is close to the hardness of ordinary steel. The applicable temperature range is from -40℃ to +120℃, and it can withstand short-term high temperature of 150℃. The surface drying time is 1 hour, the actual drying time is 4 hours, and the full curing time is 18 hours. The surface roughness after polishing can reach Ra≤0.8μm, which meets the surface accuracy requirements of hydraulic cylinders. The adhesion strength meets ASTM D3359 standard level 5B, and it is resistant to hydraulic oil, industrial lubricating oil and weak acid. The packaging is a double-component plastic tube, which is convenient for storage and use. The shelf life is 12 months under unopened conditions, and it is compatible with brushes, sandpaper and polishing equipment.
This product is suitable for repairing wear, scratching and corrosion of hydraulic cylinder rods and cylinders in construction machinery, engineering vehicles, forklifts, injection molding machines and other scenarios. The target industries include construction machinery, logistics, manufacturing and other industries that use hydraulic equipment. A typical application case: a construction company repaired the worn hydraulic cylinder rod of an excavator with this product, and only spent $59.99 and 6 hours to complete the repair, avoiding the cost of replacing the entire hydraulic cylinder which is more than $5,000, effectively reducing maintenance costs and downtime. It can also be used for repairing wear of hydraulic systems of machine tools and injection molding machines, and has been widely praised by maintenance teams for its convenient construction and good repair effect.
