A non-foamed aqueous composition can be applied to fabric substrates to provide non-foamed light-attenuating coatings in resulting coated fabric substrates that produce reduced glare from incident outside light. The non-foamed aqueous composition used to make these coated fabric substrates has a 5-50% solids and a zero shear viscosity of 100-1000 mPa-sec at 25° C. This composition has components i) through iv): i) porous particles at 0.1-20 weight %, and optionally an opacifying colorant; ii) a film-forming binder material comprising at least a chlorinated polymer at 4-20 weight %; iii) a white inorganic particulate filler material having a refraction index (RI) greater than 2 and a median particle size of less than 1 μm, at 5-16 weight %; and iv) a white low-density particulate hydrated alumina having a median particle size of less than or equal to 3 μm, at 2-16 weight %.

The present invention provides a water-based coating and/or coating system used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions as primer coats on substrates, and methods for applying the same to substrates. The method includes steps of applying a water-based paint to the interior surfaces of a substrate and drying the substrate by continuously forcing heated air onto the substrate as it moves through a drying chamber. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
