Publication number: 20150191626Abstract: A process for multilayer coating of substrates includes applying a base coat layer of a water-based color- and/or special effect-imparting base coat composition onto a substrate, applying a clear coat layer of a transparent clear coat composition onto the base coat layer, and curing the clear coat layer. The base coat composition contains a water-dilutable polyurethane hybrid binder, obtained by polymerization of a polyurethane macromonomer, containing a lateral and/or terminal vinyl group, in the presence of an unsaturated monomer copolymerizable with the polyurethane macromonomer, a curing agent, and a pigment. The polyurethane macromonomer is based on a polyhydroxyl compound. The polyhydroxyl compound comprises at least about 50% by weight of at least one polycarbonate polyol, which is liquid at 20° C., the % by weight based on the total amount of the polyhydroxyl compound.Type: ApplicationFiled: June 26, 2013Publication date: July 9, 2015Inventors: Carmen Flosbach, Paul P. Bruylants, Jean-Luc Wietor

Publication number: 20150147578Abstract: The present invention relates to multilayer coatings of an optionally pre-coated substrate and processes for the multilayer coating of substrates. The multilayer coatings comprise a base coat layer of a water-based colour- and/or special effect-imparting base coat composition disposed on the optionally pre-coated substrate. The multilayer coatings further comprise a clear coat layer of a transparent clear coat composition disposed on the base coat layer. The water-based colour- and/or special effect-imparting base coat composition is a water-based coating composition comprising A) at least one water-dilutable polyurethane binder, B) optionally at least one curing agent, and C) at least one pigment. The at least one water-dilutable polyurethane binder is based on at least one polyhydroxyl compound, said polyhydroxyl compound comprises at least 50% by weight of at least one polycarbonate polyol, which is liquid at 20° C., the % by weight are based on the total amount of the polyhydroxyl compound.Type: ApplicationFiled: February 2, 2015Publication date: May 28, 2015Applicant: AXALTA COATING SYSTEMS IP CO., LLCInventors: ANDREAS FIEBERG, CARMEN FLOSBACH, PAUL P. BRUYLANTS, JOZEF THERESIA HUYBRECHTS

Publication number: 20120276296Abstract: The present invention relates to water-based coating composition comprising A) at least one water-dilutable polyurethane binder, B) optionally at least one curing agent, and C) at least one pigment, characterised in that the at least one water-dilutable polyurethane binder is based on at least one polyhydroxyl compound, said polyhydroxyl compound comprises at least 50% by weight of at least one polycarbonate polyol, which is liquid at 20° C., the % by weight are based on the total amount of the polyhydroxyl compound. The invention also relates to the use of the water-based coating composition as base coat composition in a multilayer coating comprising a layer of a base coat composition and a layer of clear coat composition thereon. The water-based coating composition can be used as colour- and/or special effect imparting base coat composition in a multilayer coating comprising a layer of a base coat composition and a layer of a clear coat composition thereon.Type: ApplicationFiled: December 20, 2010Publication date: November 1, 2012Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: Andreas Fieberg, Carmen Flosbach, Paul P. Bruylants, Jozef Theresia Huybrechts

Patent number: 4945145Abstract: A curable silane resin, and a process for making same, having at least one of two units selected from the group consisting of a prepolymer (C) and a prepolymer (F); the prepolymer (C) having the formula (I): ##STR1## and the prepolymer (F) having the formula (III): ##STR2##The curable resin of our invention has excellent flexibility, solvent resistance and adhesion to organic materials. Furthermore our process for preparing the resin is simpler, more easily reproducible, and results in less unwanted by-prodducts than earlier processes for preparing similar silane resins.Type: GrantFiled: April 6, 1989Date of Patent: July 31, 1990Assignee: E.
