Waterborne polyurethane dispersion (PUD) is produced by dispersing polyurethane polymer in water using a stabilizer or emulsifier. The process involves the reaction of isocyanate with a polyol, by dispersion in an aqueous medium using suitable emulsifiers. The resulting PUD is a stable, aqueous dispersion of polyurethane particles, which can be dried to produce an adhesive, coating, or film. The advantages of waterborne polyurethane dispersion include: 1. Environmentally friendly: Waterborne PUDs are free of volatile organic compounds (VOCs) and other harmful chemicals, making them safe for the environment and human health. 2. Low odor: Waterborne PUDs have a low odor and are suitable for use in enclosed spaces. 3. Superior performance: Waterborne PUDs offer superior mechanical and chemical properties, such as flexibility, abrasion resistance, and adhesion, compared to other water-based polymers. 4. Versatility: Waterborne PUDs can be used in a variety of applications, including coatings, adhesives, and films for textiles, leather, and automotive industries. Overall, the production of waterborne polyurethane dispersion is a highly versatile and environmentally friendly process that offers superior performance and low odor properties, making it ideal for a wide range of applications.
