  • Patent number: 10040966
    Abstract: The present invention is directed to an aqueous architectural composition comprising a low Tg (less than about ?10° C. and higher than about ?50° C.) acrylic emulsion polymer with at least one cross-linkable moiety, and solid polyutherane (PU) or polybutylacrylate microspheres having a mean weight diameter of less than about 40 microns and a Tg of less than about 0° C., wherein the solid PU spheres make up about 10% to about 20% by weight of the composition. The solid acrylic polymer without water and the PU spheres make up about 30% to about 40% by weight of the aqueous composition. A dried paint film formed by the inventive aqueous architectural composition can withstand at least about 500 cycles on the scrub test, and a gloss value at 60° of less than about 2.5 GU.

  • Patent number: 9453133
    Abstract: The architectural compositions, such as paints and stains, include an additive comprising a plurality of latex particles added to an existing mixture of opacifying pigments and a film-forming binder as an admixture. Each latex particle is made from a latex polymer copolymerized with a polymerizable surfactant. The latex polymer is a non-film forming polymer at ambient temperatures.

  • Publication number: 20090149591
    Abstract: The invention is related to glossy, low- or zero-VOC aqueous paint compositions, comprising water based latex polymer, a hiding pigment, at least one low-VOC coalescence aid having a volatile organic content of less than 50 g/L, and a second inorganic pigment with particle size ranging from about 1 to 100 nanometers. The paint composition gives good block resistance and mechanical strength and can be adopted for paints with at least glossy and semi-gloss finishes.

  • Publication number: 20090023850
    Abstract: Paint systems, in accordance with exemplary embodiments, of the present invention include a foundation base component and a top coat component. The foundation base component is tinted to match the top coat component to provide both the desired amount of hiding of colors or markings on the substrate to which the paint system is applied, and to enhance the brightness and hue of the color of the paint system. Furthermore, in another innovative aspect of the present invention, the foundation base component comprises at least one low molecular weight polymer that undergoes self-crosslinking at ambient conditions during and after paint drying. The low molecular weight polymer penetrates various substrates, including chalky surfaces, to provide improved adhesion. Moreover, because the low molecular weight polymer is self-crosslinking at ambient conditions, the polymer enhances the performance of dried paints, including improving mechanical strength, tannin block properties, and weatherability.
