ABSTRACT:
Evidence for the three-soil-layer concept, and data on the positive performance of candidate fluorocarbon coating on glass and transparent plastic films after 28 month, of outdoor exposure, are presented. Including soil theory, soil layers, and results.

A broad information search was carried out in four areas: glazings, housing materials, acrylic coatings, etching processes and AR coatings.
An extensive list of all (known) U.S. transparent polymers was developed as well as tables of plastic, ceramic and metallic materials that could conceivably function as a housing. In addition, a compilation was made of commercially available solvent and water-base acrylic coatings for use as a UV protective coating for the glazing.
Twenty transparent polymers were chosen as possible glazings and twelve materials (plastic and wood) as possible housings and exposed in the Weather-Ometer. The glazing materials were also exposed outdoors at Hazardville, Connecticut, in the EMMAQUA in Arizona, and under the "Wet" RS-4 Sunlamp. Solar optical transmission and tensile properties were measured periodically. Several acrylic coatings containing UV absorbers were investigated as protective coatings for glazings and the coated glazings were exposed in the EMMAQUA. Tedlar 20 and Halar 500, with strong absorption in the UV, and two commercial films containing UV absorbers, Tedlar UT and Korad 201-R, were laminated by several different processes to four promising glazing materials and exposed in the Weather-Ometer. Antireflective coatings and surface etching processes were explored as a means of increasing transmission by reducing reflection.… (lisätietoja)
