A cyanoacrylate-based adhesive composition is disclosed. The cyanoacrylate-based adhesive composition includes a cyanoacrylate monomer, and a bleachable dye including a Michler's hydrol cation or derivatized Michler's hydrol cation, paired with a non-nucleophilic anion that provides a stable color to the cyanoacrylate-based adhesive.

Fluorochemical urethane compositions comprising one or more fluorochemical urethane compounds, and one or more auxiliary compounds for treatment of a fibrous substrate are described. The fluorochemical compositions are capable of improving one or more of the oil- and/or water repellency, stain- and/or soil repellency and stain and/or soil release properties, with improved durability, of the fibrous substrate treated with the fluorochemical composition.

A method of slot extrusion coating is provided that can be used to apply thin coatings using liquid compositions having high percent solids. A window of operability advantageously identifies the limits of a process to provide these thin high solids coatings. The window of operability is determined by obtaining a first graphical curve representing actual values of wet thickness as a function of percent solids level. The critical wet thickness is then identified on the first graphical curve. The window of operability is identified as an area defined by the boundaries: percent solids greater than the point at which critical wet thickness occurs, an actual wet thickness greater than all points above the first graphical curve and equal to or less than the critical thickness.

This invention relates to chemical compositions comprising one or more urethane oligomers of at least two repeating units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon-containing urethane oligomers. These urethane oligomers comprise the reaction product of (a) one or, more polyfunctional isocyanate compounds; (b) one or more polyols; (c) one or more monoalcohols selected from the group consisting of fluorochemical monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof; (d) one or more silanes; and optionally (e) one or more water-solubilizing compounds comprising one or more water-solubilizing groups and at least one isocyanate-reactive hydrogen containing group. The chemical compositions of the present invention can be applied as coatings and these coatings can impart stain-release characteristics and resist being worn-off due to wear and abrasion.

Novel polymeric compounds having pendent fluoroaliphatic groups, pendent organic-solubilizing groups, and pendent groups capable of reacting with an epoxy silane; which have been reacted with an epoxy silane have been discovered. These compounds are easy to apply, abrasion and impact resistant, and provide durable, low surface energy, streak reducing surfaces on coating dies, edge guides, and other coating and fluid contacting surfaces.
