A fast drying, heavy metal-free, high performance coating composition with outstanding UV resistance, and excellent corrosion resistance coupled with fast dry and long pot life. This coating can be applied over DTM, such as blasted cold rolled steel, or treated cold rolled steel, aluminum and treated aluminum. High corrosion resistance without sacrificing gloss or UV resistance achieved by selecting proper pigments and proper pigment design and packing by advantageously utilizing differing pigment morphologies (sizes and shape).

C. under 1 atm, (C) from 1% to 8% by weight of a lubricant having an average particle diameter in a range of from 100 nm to 600 nm measured by dynamic light scattering according to ISO13321:2004, and (D) from 0.1% to 1% by weight of a water-soluble chromium compound, where its weight is calculated from the chromium element, and the weight percentages of all components are based on the total weight of the aqueous composition.

A composition includes a plurality of pigment particles including a metal oxide, a polymeric first dispersant, and a second dispersant including molecules having a lower molecular weight than the first dispersant. The composition may be used in a hardcoat.

A coating solution that is sprayable and reflective across the UV, visible, and near-infrared wavelength ranges is described herein. Potassium bromide is used as a binder to integrate microscale ceramic bubbles. The spray coating not only provides high reflectivity all across the solar wavelengths, but also a high mid-infrared emissivity for effective surface cooling in ambient environments. Tests with concrete samples show that the spray coating allowed for significantly more cooling compared to commercially available white paints and even sub-ambient cooling under sunlight.

A barrier layer applied to a cellulose substrate to protect sensitive substances. The cellulose substrate is coated with the barrier layer composition. An aqueous mineral suspension and an aqueous composition for preparing the barrier layer composition includes a polymeric stabilising agent prepared from (meth)acrylic acid and a polyalkoxylated methacrylic derivative.
