A composition comprising recycled paint and a thermal shock resistant material, a method of making the composition, and a method of applying the composition to a surface to prevent crack or leakage.

Disclosed are methods for producing heat sealable multilayer paperboards including precoating layer including polyvinyl acetate acrylate latex binder and one or more water-based barrier layers. Heat sealability of the multilayer paperboard was significantly better than heat-sealability of a multilayer paperboard wherein the precoating was omitted or wherein the precoating incudes typical binders such as styrene butadiene latex or styrene acrylate latex but no polyvinyl acetate acrylate latex. Also disclosed are heat sealable multilayer paperboards obtainable by the method and use of polyvinyl acetate acrylate latex in precoating composition for improving heat sealability of a multi-layer paperboard.

A fire retardant, vapor impermeable coating composition is disclosed which is useful for protecting gypsum, wood, polyurethane, polystyrene, and other construction materials and surfaces, such as components for buildings. The composition does not require halogenated compounds and is considered environmentally friendly. The composition is provided in the form of a liquid-applicable aqueous latex comprising at least one latex polymer and an expandable graphite, optionally a hydrophobic thickener, and optionally other fire retardants such as metal hydroxides, wherein the polymer is selected such that the composition, when coated onto a substrate and allowed to dry, has a vapor permeability not exceeding one perm (5.7010.sup.8 g/Pa.Math.s.Math.m.sup.2 when tested according to ASTM E96B-10 at an average dry film thickness of 40 mils). The invention provides fire retardant air barrier layers for construction materials, such as polyurethane or polystyrene insulation beads or panels, as well as vapor impermeable laminates for construction applications.

The invention relates to compositions based on an aqueous dispersion of one or more polymers and intended for coating various types of surfaces, including metal surfaces with oxide scale and rust. The compositions according to the inventions include a polymeric film-forming agent, preferably based on a synthetic polymer, with pH from 1.5 to 12.0, one or more phosphonic acids and water, as well as one or more compounds selected from N-alkylpyrrolidones. The composition includes a compound selected from N-alkylpyrrolidones in combination with phosphonic acids (such as NTPA and OEDPA) may produce a coating with a gloss, which is uncharacteristic for aqueous dispersion compositions, essentially higher adhesion to any substrates, and enhanced protective properties in aggressive media and in various climatic conditions.
