COMPOSITIONS AND METHODS FOR PRODUCING COATINGS WITH IMPROVED SURFACE SMOOTHNESS AND ARTICLES HAVING SUCH COATINGS |
摘要 |
A coating composition produces a protective coating to a substrate, which coating has an improved surface smoothness. The coating composition comprises a mixture of at least a first type of particles and a second type of particles that are dispersed in a liquid medium. The particles form a total population of particles having a median ESD in a range from about 1 to about 7 micrometers. The different types of particles have different median ESDs. The first type of particles has a maximum ESD of about 40 micrometers, and the second type of particles has a maximum ESD of about 20 micrometers. A method for producing a coating having an improved surface smoothness comprises applying such a coating composition on a substrate and curing the coating composition to produce a protective coating. The coating may be further densified by a burnishing process or further improved by applying another coating comprising particles having ESDs less than about 4 micrometers.
