A pseudo-stable phase-splitting solvent composition that forms a single liquid phase when subjected to mild agitation and retains that single phase while the composition is applied to a surface, but which forms two or more laminar liquid phases promptly after being applied. A concentrated solvent film forms on the surface, under a film containing the other phase. The solvent preferably is denser than water, and the composition preferably is diluted with water. This enables the solvent to attack the surface at near full strength, and provides a water seal over the solvent film. The solvent composition can be used full strength or in diluted form for cleaning, reducing the microbial population of, or degreasing a variety of surfaces, and for stripping a variety of difficult-to-remove coatings from surfaces.

Phase-separating solvent composition

The present invention is directed to compositions for removing silver soil from the surface of objects. These compositions contain a reducing agent, and an alkaline source, and may optionally contain various other components including a chelating agent, cleaning agent, filler, an anti-corrosion agent, a defoaming agent, an odorant, a dye, an antioxidant, or a bleaching agent. Methods of using the compositions are also disclosed, wherein the object to be cleaned is contacted with the composition and the object is then washed with an aqueous solution.

Methods for removing silver-oxide

A UV cured floor finish can be removed from a floor by applying to the cured finish an inhomogeneous stripper composition containing at least one polar solvent, allowing the stripper composition to contact the finish for sufficient time to soften the finish, and removing the softened finish from the floor by mopping, vacuuming, mild abrasion or other measures that do not remove substantial portions of the floor. Preferably the polar solvent is denser than water and preferably the stripper composition has a diffusion rate through the cured finish greater than about 7&times;10 g/cm /sec. Strippable floor finish kits can be manufactured by combining a UV curable floor finish composition and an inhomogeneous stripper composition containing at least one polar solvent.

A waterborne radiation curable coating composition containing at least one acrylate functional oligomer having a functionality greater than 3 and at least one vinyl ether oligomer having a functionality greater than 1 provides a cured coating resists deep scratches.

Highly durable waterborne radiation cured coating

Continuous coatings including floor finishes can be prepared using novel two part compositions and methods. The two part compositions comprise a solid particulate polymer part and a liquid coalescing agent part. A novel method of the invention involves contacting the coalescing agent with the polymer in a variety of coating methods including applying the polymer to the coalescing agent, applying the coalescing agent to the polymer or applying the coalescing agent and polymer simultaneously. The polymer and coalescing agent interact to form a continuous coating layer or finish layer.

A jobsite-applied radiation curable floor finish containing inorganic particles can be applied to a multipiece flooring material whose pieces have a top surface, a side surface or surfaces and gaps between pieces. The top surface is coated and at least the uppermost portion of the gaps are filled with a layer or layers of cured finish composition comprising radiation cured polymer and sufficient inorganic filler particles to impart increased scratch resistance to the cured finish. The finish can also be applied as a strip agent-permeable coating atop a strippable intermediate coating atop a substrate.

Scratch-resistant strippable finish

A radiation cure device ( ) has a removable light housing ( ). The cure device ( ) utilizes a fixed output power supply ( ), a shutter mechanism ( ) and is easily maneuverable because of its lighter weight. The light housing ( ) is laterally offset and is adjustable in a lateral direction.

Portable radiation cure device

An on-site apparatus and method for preparing aqueous cleaning compositions, including an electrolytic cell for producing and dispensing chlorine and sodium hydroxide for use in various cleaning and/or sanitizing formulations at the point of use.

Point-of-use generation of chlorinated alkaline cleaning solutions by electrolysis

The passage of a container along a conveyor is lubricated by applying to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container a coating comprising a hydrophilic material wherein the lubricating properties of the coating are enhanced by contact with a polar liquid; polymerizing or otherwise solidifying the coating; and contacting the coating with such polar liquid. If desired, the coating can be applied or polymerized on the conveyor or container while the conveyor line is in motion.

A UV cured floor finish can be removed from a floor by applying to the cured finish an inhomogeneous stripper composition containing at least one polar solvent, allowing the stripper composition to contact the finish for sufficient time to soften the finish, and removing the softened finish from the floor by mopping, vacuuming, mild abrasion or other measures that do not remove substantial portions of the floor. Preferably the polar solvent is denser than water and preferably the stripper composition has a diffusion rate through the cured finish greater than about 7&times;10 g/cm /sec. Strippable-floor finish kits can be manufactured by combining a UV curable floor finish composition and an inhomogeneous stripper composition containing at least one polar solvent.

Continuous coatings are prepared using novel two part compositions and methods. The two part compositions of the invention comprise, in separate containers, a powder polymer composition and a coalescing agent. The powder composition has preferred particle size distribution and composition for use in the compositions or methods of the invention. The coalescing agents of the invention cooperate with the powder part to result in a excellent finish having the appropriate drying hardness, durability, etc. The novel method of the invention involves contacting a coalescing agent with polymer particles in a variety of coating methods. The particles and the coalescing agent interact to form a continuous coating layer or finish layer. The basic coating formation methods of the invention can be embodied in a number of methods or protocols including applying a solid polymer to the liquid coalescing agent, applying the agent to the polymer particulate or applying the liquid and polymer simultaneously. In any protocol, a desirable floor finish can be easily formed. This invention is particularly suitable for a floor finish composition.
