A reflective particulate material comprises a particulate substrate, and a coating on the particulate substrate. The coated reflective particulate material may have a relative error of an amount of the coating on the particulate substrate of about 5% to about 15%, and/or a dust index of about 5 or lower, and/or a staining loss of about 8% to about 11%. A method of manufacturing the reflective particulate material comprises mixing the particulate substrate with a liquid coating composition to form a wet particulate mixture, passing the wet particulate mixture through at least one heat zone to remove water and/or moisture, and curing the coating material in the coating composition.

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.

Described is a method for producing a coating with an aqueous coating composition AC, the method including: a) applying the aqueous coating composition AC to a cementitious substrate; and b) curing the applied aqueous coating composition AC. The aqueous coating composition AC includes at least one amino-functional copolymer VC and at least one epoxy silane ES and the coating composition has a pH in a range of 3 to 6.5. The weight ratio between amino-functional copolymer VC and epoxy silane ES (VC/ES) is in a range from 1.0 to 9.5. The composition can display self-etching properties on concrete surfaces, and thus, cementitious substrates do not have to be mechanically or chemically pretreated before the composition is applied.
