Abstract

Embodiments may include a coated granule for roofing systems. The coated granule may include an aluminum silicate granule and a coating disposed on the aluminum silicate granule. The coating may include a copolymer and a siloxane-based or a silane-based compound. The copolymer may be a cationic fluorinated (meth)acrylic copolymer. The aluminum silicate granule may have a particle size in a range from 0.2 mm to 2.4 mm. The aluminum silicate granule may have a 65% or greater reflectivity. The coated granule may repel oil and maintain its reflectivity better than with other techniques.
