The present disclosure provides for a coating formulation that includes a pigment, an organic aqueous emulsion and an organophosphonic acid of the formula: where R is a saturated or unsaturated alkyl having 2 to 10 carbon atoms or a substituted or unsubstituted aryl having 5 to 10 carbon atoms. The coating formulation can be used in forming a topcoat in an exterior insulation and finish system (EIFS). The present disclosure also provides for a method of forming a topcoat on a surface of the EIFS that helps to protect the underlayment of the EIFS against both weathering and moisture while helping to maintain color retention.

Water resistance for organic facades

The present invention relates to a process for preparing a blend of comprising an aqueous dispersion of polymer particles, a PMHS, an opacifying pigment, and an extender. The blend of the present invention is useful in exterior paint applications, especially where retention of color in the painted substrate is important.

Method for preparing coating composition with improved color retention

An aqueous coating composition including: a first emulsion polymer including, as copolymerized units, 5% to 50% styrene monomer, by weight based on the weight of the first emulsion polymer, wherein the glass transition temperature (Tg) of the first emulsion polymer is from 55&#xb0; C. to 110&#xb0; C.; a certain optional second emulsion polymer; and from 20% to 35%, by weight based on the total weight of the first emulsion polymer and the optional second emulsion polymer, coalescent selected from the group consisting of hexaoxatricosane, Calkyl glutarates, Calkyl succinates, Calkyl adipates, and mixtures thereof is provided. A method for providing a coating using the aqueous coating composition, particularly a coating for cementious substrates, the coating desirably providing superior hot tire pickup resistance is also provided.

Aqueous coating composition, method for providing a coating and cementitious substrate coated therewith

The present invention provides shelf-stable, non-cementitious dry mix compositions of inorganic non-cementious materials, such as sand, and water redispersible polymer powder (RDP) containing particles of a multi-stage acrylic copolymer having a calcium methacrylate salt group containing alkali-soluble resin outer stage and one or more inner stage, the particles further containing each of one or more nucleating agent having a boiling point of 150&#xb0; C. to 500&#xb0; C. and a water solubility of 3.5% or less, and one or more colloidal stabilizer, wherein the colloidal stabilizer and the multi-stage acrylic copolymer are contained in the same RDP particle.

EIFS formulations with enhance rain resistance

The present invention provides a water redispersible polymer powder (RDP) for use in the preparation of non-cementitious exterior finishing compositions such as textured paint formulations. Also provided are non-cementitious exterior finishing compositions comprising such RDPs and a method of coating a surface with such a finishing composition. When the RDP of the invention is incorporated into an exterior finishing composition such as a topcoat formulation of an external insulation finishing system (EIFS), the resultant composition provides improved dirt pickup resistance without a loss in wet abrasion resistance over conventional textured paint formulations comprising acrylic latex powders and, preferably, acrylic latexes.

Acrylic redispersible polymer powder for non-cementitious exterior finishing compositions

The present invention provides dry mix compositions and dry compositions of calcium methacrylate salt containing multistage acrylic copolymer RDP and dry anionic associative thickeners for use in the dry mix compositions so that when wet to make cement, mortar or trowellable compositions for use in Exterior Insulation Finishing Systems (EIFS), the compositions exhibit improved workability in both cementitious and non-cementitious dry mixes.

Non-cementitious organic render formulation with improved workability

An aqueous traffic paint including hard-soft polymer particles, polyfunctional amine, and volatile base is provided. The hard-soft polymer particles, which contain soft polymer and hard polymer, have a hydrophobicity characterized by a Hansch parameter of at least 3. Also provided is a method of producing a traffic marking on a road surface using the aqueous paint. The aqueous traffic paint is suitable for application to road surfaces, including oily road surfaces, and may be applied at temperatures below 15&#xb0; C.

Aqueous traffic paint and method of application

A method is disclosed of improving the drying time of a thick, exterior, waterborne coating containing a quick-setting binder by applying the coating as at least two separate layers and as &ldquo;wet-on-wet&rdquo; layers.

Method of improving the drying time of a thick coating

The invention relates to a method for producing a fast drying two or multi-component waterborne coating on a surface of a substrate. The method comprises applying a first component comprising a binder and a second component, being separate from the first component prior to application, comprising an absorber, and compositions and/or formulations prepared therefrom.

Method for producing fast drying multi-component waterborne coating compositions

A method for producing a fast-drying two or multi-component waterborne coating on a surface of a substrate is disclosed. The method includes applying a first component containing a binder composition, and a second component, being separate from the first component prior to application, including an absorber.
