INFRARED REFLECTIVE COATING COMPOSITIONS

摘要

The present invention provides an infrared reflective coating composition comprising, by weight percentage based on the total dry weight of the composition, 0.1% to 50% polymeric hollow particles, from 0.1% to 70% pigment particles and from 20% to 80% at least one polymeric binder, wherein the volume average particle size of the polymeric hollow particles is from 0.3 to 1.6µm; and wherein the volume average particle size distribution of the polymeric hollow particles is such that 90% of particle lies within ~10% of the volume average particle size. The coating composition is suitable for exterior architectural or industrial applications especially as an elastomer roof coating.
