Abstract:
A coated substrate comprises a strippable intermediate coating on a substrate, and a strip agent-permeable coating or topcoat on the intermediate coating. The topcoat is less strippable and more wear-resistant than the intermediate coating. In a preferred embodiment, the substrate comprises a floor, the topcoat comprises a UV curable floor finish, the intermediate coating comprises a metal-crosslinked acrylic, and the strip agent comprises a chemical strip agent containing a phenol alcohol. When the topcoat eventually becomes worn and must be renewed, a strip agent (e.g., chemical strip agent) can be applied to the topcoat. The strip agent penetrates the topcoat and attacks the intermediate coating, thereby enabling removal of the intermediate coating and topcoat without aggressive removal techniques such as sanding. Certain laminate finishes, strip agents, methods for using these finishes and strip agents, and methods for removing a multilayer laminate finish are used to prepare and to renew the coated substrate.
Abstract:
The present invention relates to two solvent antimicrobial compositions and methods employing these two solvent compositions. The two solvent compositions typically contain a second solvent that is not or is only sparingly soluble in a diluting solvent. The two solvent composition can form a clear single-phase solution. The two solvent antimicrobial compositions can reduce the population of microbes on various surfaces such as facilities, containers, or equipment found in food, beverage, or pharmaceutical industries at temperatures between about null70null C. to about 100null C.
Abstract:
This invention provides for primer/masking compositions that have differential adhesion properties for glass-like and non-glass surfaces. The compositions are used in a method of applying a finish to a non-glass surface which resides in proximity to a glass-like surface without substantially overcoating the glass-like surface. The method involves applying to the glass-like surface a primer/masking composition comprising a vinyl chloride copolymer emulsion, a coalescer, and a surfactant; applying the finish to the non-glass surface, and removing the primer/masking composition from said glass-like surface.
Abstract:
A cohesive coating composition (16) having differential adhesion properties is applied to window glass (12) without regard to covering adjacent trim material (14) which is to be subsequently painted. The DAC (differential adhesion composition) coating (16) is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective adhesion to glass-like surfaces, so that the coating composition (16) may be easily scraped, peeled, or otherwise lifted from the glass (12), together with any paint overlay thereon, after the painting operation of the window frame (14) is completed. When subjected to sheer forces of pulling and scraping, the cohesive properties of DAC coating (16) when considered in combination with a relatively low adhesion to glass, allows the coating (16) to be removed in long continuous strips rather than fracturing into small pieces. Indicia can also be applied to the DAC coating (16) once DAC coating (16) is applied to the glass (12) as a protective coating. Also, the DAC coating (16) can be used directly as a paint so that any paint (18) inadvertently applied to glass (12) or glass-like surfaces during a painting operation can be subsequently lifted off the glass (12).
Abstract:
A paint peeling composition contains as effective components (1) a water-insoluble high polymer compound such as unreamelamine resin, chloroprene latex, EVA latex, or polystyrene; and (2) a substance containing as an effective component thereof, a component capable of forming a group of minute bubbles in an applied coating per se, e.g., a foamed or unfoamed hollow matter, or a chemical system capable of reacting to form a gaseous foam.
Abstract:
Masking films comprise a transparent base, preferably a polyester or a polycarbonate, directly carrying a masking film in the form of a dyed transparent plastics material based upon a vinyl chloride-vinyl acetate copolymer coating, which contains an aromatic polyester-based polyurethane. The amount of vinyl acetate and polyurethane in the coating preferably comprises 30% to 65% w/w of its total polymer content.
Abstract:
This invention is a method for forming a protective, strippable, elastomeric film on a highly reflective surface. The method is especially well suited for protecting diamond-machined metallic mirrors, which are susceptible not only to abrasion and mechanical damage but also to contamination and corrosion by various fluids. In a typical use of the invention, a diamond-machined copper mirror surface is coated uniformly with a solution comprising a completely polymerized and completely cured thermoplastic urethane elastomer dissolved in tetrahydrofuran. The applied coating is evaporated to dryness, forming a tough, adherent, impermeable, and transparent film which encapsulates dust and other particulates on the surface. The film may be left in place for many months. When desired, the film may be stripped intact, removing the entrapped particulates and leaving no residue on the mirror surface.
Abstract:
A composition adapted to be applied on a mechanical piece or assembly to form a temporary protective fibre or coating contains an elastomer, a filler and an anionic surface active agent the presence of which enables the film or coating to be readily removed from the piece or assembly when required. There may be one or a plurality of plastomers also present while the filler preferably ranges from 50 to 100% of the polymer. Silica is a specified filler, the butyl ester of sulphonated ricinoleic acid and oleic acid sulphonate specified surface active agents and polychloroprene, polyisobutylene and natural rubber the specified elastomers. Zinc oxide may also be present.
