Abstract:
A method of inhibiting the loss of solar reflectance over time of an exterior elastomeric coating composition, comprising, forming said coating composition comprising an organic binder having a Tg less than âˆ’20Â° C., at least one inorganic additive, and a solid particulate organic polymer having a Tg greater than 70Â° C., wherein said solid particulate organic polymer having a Tg greater than 70Â° C. is present in an amount such that a volume ratio of said organic binder to said solid particulate organic polymer having a Tg greater than 70Â° C. is in the range of 1.6:1 to 95:1;applying said coating composition to an exterior surface; and exposing said coating outdoors for a period of greater than 18 months.
