Compared with traditional silicone sealants, this polyurethane sealant has stronger impact resistance and flexibility, which can adapt to the vibration and deformation during the operation of automobiles and heavy machinery, and will not crack or fall off. Its curing speed is faster, with a skin-over time of only 25 minutes, which can improve the construction efficiency of industrial assembly. At the same time, the product has excellent chemical corrosion resistance, which can resist the erosion of industrial chemicals such as engine oil, lubricating oil and cleaning agent, solving the pain point of insufficient durability of traditional sealants in complex industrial working conditions, and complying with RoHS environmental protection standards, without harmful heavy metals such as lead and cadmium.
Detailed parameters include: each cartridge has a capacity of 310ml, with a diameter of 70mm and a length of 300mm; the skin-over time is ≤25 minutes, and the full curing time is 6 days; the Shore hardness is 40 Shore A; the tensile strength is ≥1.8MPa; the elongation at break is ≥600%; it has passed ISO 10993 biocompatibility certification and RoHS environmental protection certification; the shelf life is 9 months, and the storage condition is cool and dry place with temperature controlled between 5°C and 25°C; it is suitable for a variety of industrial base materials such as metal, plastic, rubber and glass.
It is mainly applicable to automobile body joint sealing, heavy machinery equipment assembly sealing, industrial pipeline interface sealing, home appliance shell bonding sealing, ship component maintenance sealing and other scenarios, widely used in automobile manufacturing, heavy machinery, home appliance production, ship maintenance and other industries. Both professional maintenance teams and industrial assembly lines can use it, which can effectively solve problems such as equipment joint leakage, component loosening and environmental erosion.
