A heat exchanger includes a metal base defining a heat exchange channel for flowing at least one of a refrigerant and a coolant therein, and a coating layer coated at least a part of an outer surface of the metal base. The coating layer includes sol particles and an antibacterial material, where the sol particles include silica. The antibacterial material includes a rare earth element oxide. By combining the antibacterial agent containing the rare earth element oxide with sol, the advantages of each component can be fully utilized. On the one hand, it is easier to attach the antibacterial material via the sol, and on the other hand a surface of the metal base of the heat exchanger can have a good antibacterial and mold-inhibiting effects, which is beneficial to cost reduction.

A fire protection composition contains a binder on the basis of an alkoxysilane-functionalized polymer and a liquid carbon supplier. The fire protection composition allows application in a simple and rapid manner of coatings having the layer thickness required for the particular fire resistance time, the layer thickness being reduced to a minimum while achieving a good fireproofing effect. The fire-protection composition is formulated as a multi-component system. The fire-protection composition is particularly suitable for fire protection, especially as a coating of construction elements such as steel carriers.

An aerosol primer composition includes a film forming component and a propellant component. The film forming component includes (by weight of the composition): (a) at least one of a polyurethane and alkyd from about 10% to about 20%, (b) cellulosic particles from about 2% to about 5%, and (c) an aqueous solvent system from about 20% to about 40%. The propellant component includes dimethyl ether. The aerosol primer composition can be stored within a spray assembly and the propellant component can be configured to pressurize the film forming component for dispensing from the spray assembly as an aerosol. The aerosol primer composition can be used to prime a substrate to be painted or stained.

A process for forming a coating on a substrate including atomizing a formulation and applying the formulation to a substrate to form a coating on a substrate.

A liquid applied, silicone-based air and water barrier coating composition and its use as a silicone-based air and water barrier is provided. The barrier is generally vapour permeable and suitable for the construction industry. The liquid coating composition generally has a shelf-life of at least 9 months. The liquid coating composition comprises: (i) a crosslinked polysiloxane dispersion comprising (c) a surfactant and (d) water; (ii) a combination of rheology modifiers and at least one of the following ingredients: (iii) one or more fillers and/or (iv) one or more stabilizers.

The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with an organosilane polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof, a dialkyldihydroxysilane or a salt thereof, and an ancillary alkylsilane triol. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity. The dispersion is further useful for providing stain and corrosion resistance in coatings arising from paints.

Coating compositions are provided. In embodiments, a coating composition comprises a solvent system comprising water; a crosslinked organic additive in the form of particles and comprising a polymerization product of reactants comprising a multifunctional vinyl monomer comprising two or more vinyl groups; a binder; and optionally, one or more of a colorant and a wax. Methods of making and using the coating compositions are also provided.

The present invention relates to aqueous alkyd resin dispersions comprising a) a short oil alkyd resin comprising, in its fatty acid component a1), at least one polyunsaturated fatty monoacid a11) having at least two unsaturations per molecule and comprising at least 35% by weight of a monoacid a111) having conjugated unsaturations, the content by weight of said fatty monoacid a111), with respect to said alkyd resin, being at least 5%, preferably from 5% to 40% and more preferably from 5% to 35%, and b) at least one anionic phosphate surfactant. The invention also covers a preparation process and its use in decorative coatings. The coatings based on these aqueous dispersions exhibit improved performance qualities in resistance to blocking and yellowing, in development of hardness and in gloss.

An aqueous coating composition is provided that is useful in coating a variety of substrates, including interior or exterior portions of food or beverage cans. The coating composition includes a resin system that includes a multi-stage latex. In some embodiments, the multi-stage latex is formed using a process that includes emulsion polymerizing two or more stages in the presence of an aqueous dispersion including a water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a polyether polymer.
