US Patent:

52567168, Oct 26, 1993

Filed:

Aug 20, 1990

Appl. No.:

7/569437

Inventors:

Scott Haasl - Coon Rapids MN
Mark Kenow - Circle Pines MN

Assignee:

PDI, Inc. - Circle Pines MN

International Classification:

C08L 9106

US Classification:

524279

Abstract:

A coating formulation for secure bonding attachment to surfaces of resilient or flexible articles, including plastic foam articles and comprising a highly adherent and coherent water-based film forming mixture for coating the surface of flexible foam articles. The working solution of the coating preferably has a formulation containing: Component Acrylic emulsion; Plasticizer; Coalescing agent; Polyacrylate thickener/rheology modifier; Defoamer; Surfactant; Ammonium hydroxide; and Water. The working solution is applied to the surfaces of the article being treated and the water solvent which is present evaporates at a significantly rapid rate in the ambient to form a thick coating having a substantially dry outer surface. The film remains securely bonded to the article even though flexed and otherwise roughly treated.

Abstract:

An improved composite coating system for coating foam resin articles, including a formulation for a base coat together with a formulation for a top coat which bonds while to the surface of the base coat to form the composite. The base coat formulation is a water-based vinyl resin together with a slow evaporating coalescent and plasticizer. The top coat utilizes a solvent-based vinyl resin together with aromatic and aliphatic solvents and plasticizers. Erucic acid base monoamides are utilized for achieving desirable slip properties in the finished top coating. In order to achieve the desirable properties of the composite coatings, the latex resin-based materials are selected from those having a low glass transition temperature such as between -20. degree. C. and about 20. degree. C.
