A method for forming an emulsion polymer includes a step of forming a pre-emulsion by combining a monomer composition with a siloxane-containing composition in water and polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. Characteristically, the monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers, (meth)acrylic monomers, styrene monomers, vinyl acetate monomers, vinyl ester monomers, and combinations thereof. A paint composition that includes the emulsion polymer is also provided. This invention describes a method to provide excellent burnish and mar resistance while avoiding problems with film appearance that can result from siloxane addition.

Burnish and mar resistant resin for clear and pigmented coatings

A method for forming an acrylic emulsion includes a step of forming pre-emulsion by combining a monomer composition with an amphoteric surfactant in water and then polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. The monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers and (meth)acrylic monomers, and combinations thereof. An acrylic emulsion formed by the method is also provided.

Polymeric emulsion containing amphoteric surfactant and its application in architectural primers

A method for forming a benzophenone-containing emulsion is provided. The method includes a step of forming a pre-emulsion by combining a monomer composition with a benzophenone or a benzophenone derivative in water, the monomer composition including one or more monomers selected from the group consisting of (meth)acrylic acid monomers and (meth)acrylic monomers, vinyl acetate, aromatic monomers, vinyl neodecanoate, and combinations thereof. The pre-emulsion is polymerized by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture that polymerizes to form an emulsion polymer. This procedure implements novel and easily polymerizable benzophenone (meth)acrylates) into the polymer backbone preventing them from leaching out of finished coatings. Advantageously, the benzophenone-containing emulsions can be used to form paint coatings with dirt pick-up resistance while maintaining the excellent flexibility of paint finishes to limit cracking of the final film.

Dirt pick up resistant latex resin

A method for forming a durable latex polymer emulsion includes a step of forming a pre-emulsion by combining a monomer composition with a reactive emulsifier, a reactive silane compound, an epoxy crosslinker, and a phosphate-containing monomer in water. The pre-emulsion is polymerized by combining the pre-emulsion with a radical initiator to form a reaction mixture that polymerizes to form a hydride silicon-acrylic emulsion polymer.

Durable latex polymer dispersion

A composition for forming a hydrophilic coating includes an organic binder having an average particle size from about 1 to about 100 nm and an inorganic binder having an average particle size from about 1 to about 40 nm. The composition further includes an inorganic photocatalyst that catalyzes an oxidation-reduction reaction. Characteristically, the photocatalyst includes a photocatalytic metal oxide having an average particle size from about 1 to about 50 nm. Advantageously, coatings formed from the composition have improved stain resistance, low contact angle, and resistance to dirt adherence, while maintaining a clear optical character.

Superhydrophilic coating composition

A bar that is to be attached to a wall includes two stanchions, each stanchion supporting a portion of an elongated piece that extends from one stanchion to the other. A supporting connector having a lower portion attaches to and extends upwardly from each of the stanchions and a portion above the lower portion. A horizontal support extends horizontally from the portion above the lower portion of the connector between the stanchions and is disposed a distance D1 above each the stanchion. And, an adhesive is disposed beneath and attaches to the horizontal support and extends along a length thereof.

An acidic etcher solution for etching a substrate's surface. The acidic etcher solution includes an acid and a pH indicator, the pH indicator having at least one color transition at a pH below 7. The acidic etcher solution having an initial color at an initial pH when applied to the surface to allow determination of the evenness of the coating and the etcher having a second color at a second pH higher than the first pH wherein visual inspection allows for a determination that the etcher is substantially finished reacting.
