Paint with low light reflectivity and low fogging

Abstract

A method of coating a substrate to form a light absorbing, non-transparent film, includes the steps of: (a) providing a suspension in a solvent of: (i) a pigment, (ii) a binder which includes a polysiloxane, a polyol, or a combination thereof, (iii) a rheology modifier, and (iv) an adhesion promoter which includes a silane group; (b) spray-coating the suspension onto the substrate with the majority of the solvent evaporating before the suspension contacts the substrate in order to result in a porous coating; (c) repeating step (b) until the average coating thickness is at least 20 micrometres; and (d) curing the coating in order to result in a delta-haze of less than 1 (measured to ASTM-D1003-21 through glass) and a fog number of at least 95 fog numbers as measured by an extended SAE-J1756 photometric test at 120° C. for 168 hrs with a 21° C. collector plate temperature.
