A roof sealant composition and method for treating roof constructions is provided in which a roof sealant composition including from about 25 to 60% by weight recycled paint sludge is applied to a roof in a first coating followed by the application of a supportive mesh. A second coating of the sealant composition is applied as a top coat. Upon drying, a composite is formed which exhibits elongation of greater than 300% and a tensile strength of greater than 500 psi and provides resistance to cracking and leaks.

Roof sealant composition and method of applying

The present invention relates to a dispersion of fibrids and the use of this dispersion in resin compositions to increase the elongation of cured films formed from the resin composition.

Resin composition of improved elongation

A method of treating paint sludge containing uncured polymer resin, water and/or solvent is provided in which a paint sludge putty is formed which may be used as a replacement for polymeric components used to form compounded polymeric compositions. The treated paint sludge putty or powder comprises from about 5 to 90% by weight of the total compounded polymeric composition and may be used in a variety of compositions including pressure sensitive sealants, caulking sealants, automotive sealants, polyvinyl chloride plastics, rubbers and asphalt cement coatings, and waterbased sealers and coatings.

Method for treating paint sludge

Compounded polymeric compositions containing processed paint sludge putty as a replacement for polymeric components are provided. The paint sludge comprises from about 5 to 90% by weight of the total compounded polymeric composition and may be decatalyzed so that it contains uncured polymer for use in a variety of compositions including pressure sensitive sealants, caulking sealants, automotive sealants, polyvinyl chloride plastics, rubbers and asphalt cement coatings.

Compounded polymeric compositions utilizing processed paint sludge as a

Plastisol coatings and adhesives having reduced bulk density are provided by incorporating hollow thermoplastic microspheres, wherein the surface of the microspheres is wet by a surfactant which preferentially wets the surface of the microspheres, where the total solids content of the plastisol does not exceed the critical pigment volume concentration, and where the temperature and pressure of processing and use of the microsphere filled plastisol are kept to the minimums required for effective operation. Preferred hollow thermoplastic microspheres having a thermally bonded surface coating of a solid particulate material, such as calcium carbonate, silica, or the like are employed where the thermoplastic of the microspheres is wet by a surfactant which preferentially wets the surface of the thermoplastic and where the solid particulate material on the surface is wet by a surfactant or plasticizer which preferentially wets the solid particles are particularly effective in such plastisol coatings and adhesives.

Light weight plastisols and method of making same

A sludge powder and sealant are prepared from paint sludge. A sludge powder is generated from a paint sludge having a volatiles content of 0-50% by weight by adding a processing filler thereto. A sealant composition is prepared by thereafter or concurrently therewith adding sealant ingredients including polymer, plasticizer, curative, and other sealant ingredients such as an adhesion promoter and sealant filler materials to the sludge powder. Alternatively, a sealant composition may be prepared by adding a paint sludge having a volatiles content of 0-50% by weight to the sealant ingredients, which may include a processing filler.

Method of making sludge powder and sealant from paint sludge and sludge

An electrophoretic coatable sealant composition for use in assembling automobile bodies comprising an adhesive material selected from the group consisting of epoxys, urethanes, epoxyurethane hybrids, acrylics, epoxy-acrylic hybrids, polyvinylchlorides and mixtures thereof and a conductive filler in an amount such that the sealant composition will accept electrophoretic deposition of a primer composition yet preserve the adhesive properties of the sealant composition. The conductive filler is selected from the group consisting of non-treated furnace-type conductive carbon blacks.

A method for making a filler from automotive paint sludge is provided. Paint sludge containing water, solvent and uncured polymer resin is treated by removing a first portion of the water by mechanically drying the sludge to produce a concentrated sludge, and a second portion of the water is removed by treating the sludge with a chemical drying agent to produce a dried powder. Alternatively, the second portion of the water may be removed by agitating the concentrated sludge under a vacuum to produce a dehydrated putty. The resulting dried powder or putty can then be used as a filler in sealants and other products.

Thermally stable hot applied plastisol compositions are especially useful in the assembly of metal parts. The compositions have adhesive and sealant qualities which allow them to be used in automotive assembly plants. Compositions of the invention comprise as major ingredients finely divided polyvinyl chloride resin, plasticizer, thermoplastic polymeric resin which is solid at room temperature but softens to a flowable state at application temperature, and an adhesion promotion system. Optionally a filler, wax, heat stabilizer, pigment, wetting agent, or mixtures thereof may be added. The individual components work synergistically to get good application properties, metal adhesion, wash-out resistance, and paintability.
