The invention relates to compositions based on an aqueous dispersion of one or more polymers and intended for coating various types of surfaces, including metal surfaces with oxide scale and rust. The compositions according to the inventions include a polymeric film-forming agent, preferably based on a synthetic polymer, with pH from 1.5 to 12.0, one or more phosphonic acids and water, as well as one or more compounds selected from N-alkylpyrrolidones. The composition includes a compound selected from N-alkylpyrrolidones in combination with phosphonic acids (such as NTPA and OEDPA) may produce a coating with a gloss, which is uncharacteristic for aqueous dispersion compositions, essentially higher adhesion to any substrates, and enhanced protective properties in aggressive media and in various climatic conditions.

The invention provides a novel hydrophilic polymer and latex polymer blend coating formulation and compositions thereof, and their use on various devices (e.g., prophylactic and medical devices) to form hydrophilic and flexible coatings with durable lubricity.

The present invention relates to an anti-bacterial and anti-dust coating for air ducting. In one embodiment, the anti-bacterial and anti-dust coating comprises: a polymer emulsion; a cross linking agent; a film forming agent; a filler and anti-dust agent; an anti-bacterial agent; hardener nanoparticles; a defoamer; and water. The anti-bacterial agent can be in powder or in liquid form. The coating can be applied on the inner surface of metal air ducting to reduce dust aggregation and prevent growth of bacteria, mold and mildew that causes stains and odors inside air ducting. With the aids of nanotechnology, various specific nanoparticles are added in the waterborne polymer emulsion to provide the anti-bacterial, anti-dust, anti-acid, anti-alkali, good flexibility and hardness for the coating. The product is also tested to be flame retardant and water resistance for increased safety in air ducts.

The present disclosure provides pre-treatment compositions and related methods. As such, a pre-treatment coating composition can include an evaporable liquid vehicle and a pre-treatment coating matrix. The pre-treatment coating matrix can include from 5 wt % to 40 wt % multivalent metal salt, and from 5 wt % to 20 wt % coalescent latex binder comprising styrene-butadiene rubber, polyurethane, or mixture thereof. The composition can further include from 30 wt % to 80 wt % high Tg latex having a Tg greater than 80 C., from 0.5 wt % to 20 wt % water soluble binder, and from 3 wt % to 20 wt % wax having a melting point greater than 120 C. The weight percentages of the pre-treatment coating matrix exclude the evaporable liquid vehicle content.
