Repair System for Damaged Coatings of Navy Antenna Towers. Part II

摘要

Coating materials and cleaning and application procedures and equipment were developed for use in the repair of damaged coatings on Navy steel antenna towers. Experimental coatings were screened by laboratory-accelerated testing before field exposure. In the initial field exposure, 19 of 32 different coating systems provided good protection from corrosion for 3 years to a steel antenna positioner in a marine atmospheric environment. In a later field experiment, 8 of 12 of the better-performing coating systems provided very good protection for 15 months on two steel vortex towers in a very corrosive marine atmospheric environment. Newly developed cleaning and application procedures and equipment were tested during the latter field study. Practices by the Civil Engineering Laboratory currently recommended for coating protection of antenna towers are also presented. (Author)
