This paper reviews recent progress in the development of solventless solid urethanes for spray and spread coating applications. Formulations based on liquid MDI (Isonate 143L), equipment, compounding, handling, and processing procedures are described in detail. Solventless urethane coatings offer an attractive alternative to conventional materials and practices. Their development is aimed at eliminating atmospheric pollution from manufacturing and application processes.
