Abstract: A method of treating substrates, such as wood, including the steps of applying an alkali silicate solution to one or more substrates and applying an alkali borate solution with boric oxide (B2O3) content to the substrates. Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.

Abstract: A method of cleaning a substrate by covering the substrate with a composition in a sufficient amount to clean the substrate. The composition includes a substantial amount of at least one low viscosity organic compound which includes a radiation curable group. The compound is reclaimed for further use. The reclaimed compound may be used as a reactive diluent in a radiation curable coating composition.
Abstract: A free-radical curable polish composition is described. The composition can be applied and cured as an ultra thin film on finished surfaces to provide enhanced chemical and mar resistance. The composition comprises an aqueous emulsion including an olefin-functional polymer or an olefin-functional prepolymer, and a silicone or silicone copolymer preferably with photoinitiators for UV and EB cure. The polish/emulsion can be applied, for example, to wet the surface of nitrocellulose lacquer wood finishes. The polish wet surface is first wiped to remove excess polish and thereafter exposed to UV radiation to provide a thin, polymerized protective film.

Abstract: This invention provides novel methods for the formation of biocompatible membranes around biological materials using photopolymerization of water soluble molecules. The membranes can be used as a covering to encapsulate biological materials or biomedical devices, as a "glue" to cause more than one biological substance to adhere together, or as carriers for biologically active species. Several methods for forming these membranes are provided. Each of these methods utilizes a polymerization system containing water-soluble macromers, species which are at once polymers and macromolecules capable of further polymerization. The macromers are polymerized using a photoinitiator (such as a dye), optionally a cocatalyst, optionally an accelerator, and radiation in the form of visible or long wavelength UV light. The reaction occurs either by suspension polymerization or by interfacial polymerization.
