Coatings and Pavement Marking Materials, 1969-1972.

摘要

An evaluation was made of zinc rich primers for use on structural steel. The organic vehicle type described in this report has proven in laboratory and field tests to be essentially equal in durability to the inorganic vehicle type without the sophistication in application and liability to early failure caused by faulty application of the latter. Formulations have been made for 20-30 second dry to no pick-up heated traffic paints, and specifications of a performance type are being prepared. Formulations for four types of concrete curing compounds and a rapid dry heavy equipment and truck enamel developed are discussed. (Author)
