Abstract:
Fluorinated polymers of three-dimensional molecular structures have been derived from fluorinated epoxies, polyols and polyurethanes. A series of papers presented in the Organic Coatings and Plastics Chemistry Division beginning in 1968 at the San Francisco meeting of the ACS has given the step-by- step evaluation of these materials from basic chemical synthesis through practical coatings formulation and evolution. These new coatings are beginning to find some uses in which the fluoro-carbon nature combined with conventional paint applications techniques make them unique. The qualities of hydrophobicity, oleophobicity and exceptional resistance to electromagnetic radiation are among the most desired in protective coatings systems, and high gloss formulations which hold this quality exceptionally well during weathering have promising decorative possibilities. Special applications such as aircraft coating to lower cleaning and maintenance costs, interior coating of environmental research chambers for smog physics experiments, and use as tough, high- temperature lubricant barrier films are under evaluation. Some possible future applications, such as automobile finishes, and the projection of chemical efforts to synthesize such materials with 60 + % FLUORINE BY WEIGHT ARE UNDER STUDY.
