Abstract:
A coating system for application to a substrate having a sol-gel film layer applied thereon includes a decorative color coat applied directly on top of the sol-gel film without an intervening adhesion layer. The decorative color coat may be a solvent borne composition including a resin which is the reaction product of a crosslinked polyepoxy resin and a polyamine crosslinker, and one or more opacifying pigments. Decorative designs may be formed by selectively applying more than one layer of decorative color coats having different colors. A transparent clearcoat may be applied to the decorative film.
Abstract:
A system for applying coatings and more specifically paint coatings is provided that combines fluid stored in separate reservoir containers prior to expelling the mixture for application. The reservoirs may be comprised of collapsible and disposable bags that eject its fluid upon activation of an actuator or expanding bladder. The fluid components are combined and blended together in a mixer that is positioned between the reservoirs and a nozzle.
Abstract:
This invention relates to a curable composition comprising a solvent solution of a mixture comprising: (i) at least one hydroxy-functional acrylic polymer having a Tg of about 25°C or lower; and (ii) at least one hydroxy-functional polyester having a Tg of 0°C or lower; (iii) at least one polyisocyanate having an average functionality of >4; (iv) a metal catalyst, such as a tin compound, for accelerating the isocyanate/hydroxyl reaction; and (v) optionally a pot-life extending amount of propionic acid.
Abstract:
Methods and compositions for coating a substrate with at least a basecoat layer and clearcoat layer allow quick repairs to damaged vehicle panels under ambient temperatures and without requirement of actinic or thermal radiation to cure the layers. At least one basecoat and one clearcoat layer may be applied to a substrate and the clearcoat layer may be buffed with less than 30 minutes allocated to curing the basecoat and clearcoat layers, under ambient conditions, prior to buffing. Methods and compositions are also taught for coating a substrate with at least a primer layer, a basecoat layer, and a clearcoat layer, in which the clearcoat layer may be buffed with less than about 45 minutes allocated to curing the primer, basecoat and clearcoat layers, under ambient conditions, prior to buffing.
Abstract:
A method for refinishing a damaged area of a substrate, such as an existing finish on a vehicle which includes the steps of preparing a damaged area for refinishing, by cleaning and/or sanding, providing a multi-component coating composition which includes at least two components having functional groups reactive with each other in a crosslinking reaction and spreading the coating composition onto the area to be refinished using a squeegee applicator.
Abstract:
A 2K basecoat clearcoat system includes a solvent borne basecoat having a low Tg branched polyester polyol, optionally, a high Tg, high molecular weight thermoplastic resin, and a hardener that includes an isocyanate functional material suitable for crosslinking the polyester polyol, and optional thermoplastic resin. The solvent borne clearcoat composition includes a low Tg linear or branched polyester polyol, at least one other multi-functional polyol, and an isocyanate functional material suitable for crosslinking the polyester and multi-functional polyols.
