Features: Yantai Wanhua Polyurethane Co., Ltd. is currently the only domestic enterprise with MDI production technology and facilities, and it is also the largest urea raw material supplier in China. Yantai Wanhua MDI series products and production technology have been listed by the State Council as key encouraged products, industries, and technologies for national development. Among them, pure MDI, liquefied MDI, MDI-50, and chain extender MDBA (brand name WANALIND 6200) are the main raw materials for spray polyurethane. The company can provide polyurethane composite materials for various applications. Among them, MDI-100, MDI-50, and liquid MDI are the main raw materials for the A-component of the two-component system in polyurethane spray formulations, while WANALINK 6200 is an important chain extender in polyurethane spray formulations. At the same time, the company has newly developed the prepolymer WANNATE 8312 (viscosity 500±mmPa·s; NCO% 15.5±0.5).

Spray polyurethane elastomer technology is a new type of solvent-free, pollution-free green coating technology developed in the past decade to meet environmental demands. Based on the author's achievements and practical experience in pioneering research and development of spray polyurethane elastomer technology in China, and referencing a large number of domestic and international literature, this book systematically introduces polyurethane elastomer raw materials and additives, polyurethane chemistry, the relationship between structure and performance, spray equipment, substrate treatment and construction techniques, application fields and case studies, analysis of spray polyurethane elastomer materials, safety and protection, and more. This book is suitable for engineering technicians engaged in coating research, production, and application, as well as professionals and construction supervisors in fields such as corrosion prevention, waterproofing, wear resistance, impact resistance, reinforcement, and decoration. It can also serve as a reference for students and teachers of relevant majors in colleges and universities.
