Polyurethane catalyst can replace epoxy resin composite materials as the main raw material for wind turbine blades.
Currently, as a new type of green energy, wind power has undoubtedly become a hot topic in the global energy market in recent years. Wind power is developing rapidly in my country, and the related industries driven by it are also heating up rapidly. Multinational coatings suppliers still occupy a dominant position in the domestic wind turbine blade coatings market. Domestic coatings companies have also carried out research and development work and made significant progress. Some domestic companies have already occupied a place in the market.
Recently, PPG has launched a new type of protective coating for wind turbine blades with super weather resistance, high corrosion resistance, high toughness, lightweight and low surface energy. Polyurethane coating system. It is understood that PPG Industrial Group combines its more than 100 years of coating technology and its technology in aviation and heavy-duty anti-corrosion coatings. In order to cooperate and assist major machine companies and blade manufacturing companies to produce larger blades, the new polyurethane coating system launched is : AUE500OO corrosion-resistant and weather-resistant wind blade special coating (topcoat) and HSP7401 corrosion-resistant and weather-resistant wind blade special coating (primer). This polyurethane coating system fully considers the harsh conditions and weight requirements of large blades during use.
It has very outstanding performance in terms of weather resistance, corrosion resistance, system paint usage and flexibility at low temperatures, especially rain corrosion resistance, which meets the requirements At present, the highest technical requirements of international blade manufacturing enterprises. Moreover, this polyurethane system has the longest recoating interval. As long as there are no contaminants on the surface, it can be repaired and recoated directly, and the adhesion can also be guaranteed.
Shanghai New MaterialsPolyurethane Catalyst Products are of high quality and adhere to the principle of “innovation and quality” With the business philosophy of “equal emphasis on environmental protection and efficiency”, we continue to explore and innovate. We welcome everyone to come and cooperate.
