The composition includes a polyester resin comprising at least one α,β-unsaturated ester group, an acrylate or methacrylate, a vinyl ester represented by formula R—[C(O)—O—CH—CH.sub.2]n, wherein R is alkyl, aryl, or a combination thereof and n is 1 or 2, and a metal salt of a carboxylic acid. A method of repairing a damaged surface using the composition is also described.

A method of sealing surface imperfections on a sanded surface of a repair to a vehicle body is provided that includes an uncured layer of a formulation being applied to sanded cured body filler on the vehicle body. The formulation includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a sealing coating. The resulting seal coating has able to seal surface imperfections. A surface imperfection sealing formulation is also provided that includes a polyester resin and a multifunctional crosslinking agent. A solvent is provided. A photoinitiator renders the formulation curable upon exposure to ultraviolet light exposure. A particulate filler is also present in an amount to result in a formulation with an uncured viscosity of between 2600 and 3000 centipoises.

Removable, aqueous-based compositions, especially sealants useful for, inter alia, temporary craft applications and seasonal weatherization of buildings and methods of their use are disclosed. These sealants reduce the flammability risks and lingering odor problems associated using solvent-based systems, particularly during application. These compositions do not rely on additives that disrupt the adhesion of the compositions to the substrate and that leave undesirable residue on the substrate.

A system for installing pre-painted moldings. The system includes pre-painted moldings each configured to be fastened to a wall by fasteners. The system also includes a caulk material, filler material, concealer material, and touchup paint each color matched to the paint color applied to the moldings. The caulk material is configured to fill a gap defined between each of the moldings and the wall to which the molding is fastened. The filler material is configured to fill a gap defined between any abutting portions of the moldings. The concealer material is configured to conceal any surface disturbances caused by the installation of the fasteners. The touchup paint is configured to adhere to the paint pre-painted on the moldings. The system may also include a marker configured to apply a coating color matched to the paint applied to the moldings, a scraping tool, and/or a buffing tool.

Disclosed herein include methods of detecting and measuring enzymatic activity in coating compositions comprising one or more enzymes contained therein, for example following film formation of the coating compositions. Media-based assays and spectrophotometric-based biochemical assays for analysis of in-film enzymatic activity are provided. Methods of configuring coating compositions to enable spectrophotometric-based analysis are also provided.

An aqueous surface coating solution composition and a polyester film structure are provided. The aqueous surface coating solution composition includes 5-20 wt % of a resin composition and 0.15-5 wt % of an inorganic particle dispersion liquid. The resin composition includes 0.01-10 wt % of a polyester resin, 2-19 wt % of an acrylate-grafted polyurethane resin, and 0.5-10 wt % of a cross-linking agent. The inorganic particle dispersion liquid includes a plurality of first inorganic filling particles and a plurality of second inorganic filling particles, and the first inorganic filling particles have a larger average particle diameter than the second inorganic filling particles.
