An object is to provide a coating solution for coating a metal sheet to be subjected to complicated forming for which press forming is difficult, so as to form a film that exhibits low sliding resistance in a portion prone to cracking during press forming and excellent press formability in a portion subjected to a high contact pressure where occurrence of die galling is anticipated. A coating solution containing an acrylic resin having a glass transition point (Tg) of 100°C or higher and an acid value-to-glass transition point ratio R = acid value (mg-KOH/g)/Tg (°C) of 1.50 or more, and a polyolefin wax having a melting point of 100°C or higher and 145°C or lower and an average particle diameter of 3.0 µm or less is applied to a metal sheet.

A process for the preparation of modified polymers by a photo-initiated polymerization includes preparing a polymerization medium comprising at least one photoinitiator comprising at least one phosphorous oxide (P═O) group or at least one phosphorous sulfide (P═S) group, and at least one polymerizable monomer. The at least one polymerizable monomer is polymerized by irradiating the polymerization medium with electromagnetic radiation so as to induce a generation of radicals so as to obtain a polymer. The polymer is modified by irradiating the polymer with electromagnetic radiation so as to induce a generation of radicals from the polymer in a presence of at least one modifying agent.

A process for the preparation of a thixotropic aqueous coating composition comprising the steps of: i) providing an aqueous dispersion of a binder system comprising carbonyl and hydrazide functional groups for crosslinking; and ii) reacting in the aqueous dispersion, an ether amine with a tris(isocyanate) isocyanurate to form a polyurea sag control agent.
摘要:
The present invention relates to a new formaldehyde- free binder composition, to the related method of its use for making fibrous products (including glass fiber products and especially fiberglass insulation), and to the fiber products themselves. The present invention specifically relates to an aqueous binder composition containing a mofified copolymer of maleic anhydride and a vinyl aromatic compound such as styrene. The copolymer is modified by reaction with a primary alkanolamine (preferably mono ethanol amine (MEA) ). The modified copolymer is self-curing and cures as a consequence of cross-linking, esterification reactions between pendant carboxyls and hydroxyl groups on the solubilized (hydrolyzed) modified copolymer chains. Additional polyol (s), including diethanolamine and/or triethanolamine, can be added to the binder to increase either, or both the pH of the aqueous binder composition and the crosslink density of the cured binder.
