    摘要： A film-forming composition, typically a topcoat, having improved adhesion to certain commercially available adhesives. The composition includes a curable film-forming polymer, typically an acrylic and/or a polyester polymer, with carbamate and/or urea groups. The composition further includes a material containing one or more hydrolyzable silyl groups. The hydrolyzable silyl group-containing material optionally can be a polymeric or oligomeric. Also disclosed are a method of applying the above-described film-forming composition to a substrate and the coated article prepared by such a method.

    摘要： A coating composition is provided comprising (a) a polymer containing reactive functional groups; (b) a curing agent having reactive functional groups that are reactive with the functional groups in the polymer in (a); and (c) a polymeric material different from (a) and (b) having functional groups. The functional groups in components (a) and (b) are more reactive with each other than with the functional groups in component (c) such that upon curing, at least a portion of the functional groups on component (c) remain unreacted. A coating layer formed from the composition upon application to a substrate has surface regions and a bulk region, and the concentration of component (c) at one or more surface regions is greater than the concentration of component (c) in the bulk region of the coating layer. The composition can be used in multi-layer composites containing two or more coating layers.

    摘要： A method and apparatus for performing an enzyme spot test without traditional instrumentation is disclosed. The method utilizes various reagents to allow the visual determination of the presence of an enzyme in a sample above a predetermined critical level. The enzyme reacts with the reagents producing a product according to a reaction which is timed by a chemical fuse. At the end of the reaction, a colored by-product is visible, the color intensity indicating that the enzyme occurs in the sample in quantities above the critical level.
