Filed:

Jan 17, 2002

Appl. No.:

10/052038

Inventors:

Dong Tian - Lancaster PA, US

Assignee:

AWI Licensing Company - Wilmington DE

International Classification:

C08K 3/20

US Classification:

523406, 523414, 523415, 523416, 523417, 524507, 524512

Abstract:

Waterborne coating compositions, methods of applying such compositions, and substrates coated with such compositions are described. The compositions include an aqueous dispersion of a polyurethane resin, an epoxy resin, and a polyvinyl chloride resin. The compositions can also include an aminoplast such as a melamine, and one or more curing agents. Additionally, the compositions can include flatting agents, colored metallic and/or polymeric particles, hard particles, surfactants, rheology modifiers, defoamers, and coalescing aids. The coating composition can be applied to virtually any surface and cured using conventional heat curing techniques, whether or not there is a chemically embossed layer. However, it is advantageously used in surface coverings in combination with a chemically embossed layer. In one embodiment, the surface covering includes a chemically embossed layer and a cured top layer, which are both cured in a single heating step or plurality of heating steps.

US Classification:

428156, 428158, 428161, 428198, 427494, 427493, 427504, 427510

Abstract:

Methods for providing surface coverings with differential gloss, and surface coverings prepared by the method, are disclosed. The methods involve screen printing or rotogravure printing a relatively low gloss primer onto portions of a substrate surface covering. The primer-coated substrate is then coated with a relatively higher gloss coating composition, and the coating compositions are cured, advantageously in a single curing step. The result is a surface covering including a top coat having a lower gloss level overlying the primer and a higher gloss level in the regions not overlying the primer.

International Classification:

G11B 5/64

US Classification:

428143, 428141, 4289088

Abstract:

A floor covering has an exposed surface with substantially the same gloss level and at least two portions having different tactile surface characteristics. The difference in the tactile surface characteristics between the two portions is at least an average RPc of 4. The floor covering includes a substrate and a high performance coating overlying the substrate. The high performance coating comprises texture particles, which may be organic polymer particles. The floor covering is made by forming a high performance coating including the texture particles on a substrate, at least partially curing the high performance coating, and then while controlling the temperature of the high performance coating below the melting point temperature or softening point temperature of the texture particles and above the temperature at which the texture particles deform under the applied mechanical embossing pressure, subjecting the first and second portions to different mechanical embossing conditions.

Abstract:

A radiation curable biobased coating, such as a UV/EB curable biobased coating, for flooring applications includes a biobased component comprising renewable and/or biobased materials. The biobased component is selected from the group consisting of a biobased resin, a biobased polyol acrylate, or a biobased polyol. The biobased component is blended with a coating formula. The coating formula includes at least one initiator. The radiation curable biobased coating contains at least about 5% weight of renewable materials or biobased content.
