The invention pertains to a coating for application to a substrate, whereby the coating comprises at least one the thermoplastic fluorine-containing polymer, and its hardness decreases from the first surface, which is destined for application to the substrate, in the direction of the second surface which is remote from the substrate. The hardness gradient can be achieved by adding filling or reinforcing agents or by addition of at least one thermoplastic polymer. The invention additionally perta...

A coating apparatus is provided in which entrained air flow of an applicator roll and a web is removed and occurrences of misting and coating irregularity are suppressed to thereby realize a uniform coating liquid film and a uniform coating state. A coating apparatus includes an applicator roll arranged to abut on another roll so as to form a nip portion therebetween and to transfer a coating liquid to be coated on a surface of a web passing through the nip portion. The coating apparatus further...

The invention relates to a conductive infrared-absorbing coating material consisting of indium tin oxide. According to the invention, said coating material has a yellow index of above 15.

An antifouling coatingwhich comprises a varnish comprised of a metal-containing acrylic resin having, in a side chain thereof, at least one group represented by the following formula (1): ##STR00001## wherein X represents a group of the formula: ##STR00002## n represents 0 or 1; Y represents a hydrocarbon group; M represents a metal; m represents an integer equal to [(the valence number of metal M)-1]; A represents an organic acid residue derived from a monobasic acid,said varnish having a nonvo...

The invention provides coating material compositions comprising stable adducts which, at relatively high temperatures, generate radicals that possess initiating activity, and also provides processes for preparing them, and for the use of such coating material compositions. Stable adducts of this kind may be used in order to initiate polymerization of ethylenically unsaturated monomers.

Disclosed herein is a coating system for pre-coating a vehicle chassis, comprising a coating station and a curing oven, the coating station being upstream from said curing oven along a travel path, the coating station to deliver a layer of coating material thereon, the chassis having a number of sites, each of which is known to be source for accumulating excess coating to cause unwanted drips thereof during curing, further comprising a plurality of nozzles, each being in a nozzle group of one or...

The present invention relates to a process for the coating of objects made of valve metals or their alloys with a thin barrier layer consisting of the metal and an oxide ceramic layer provided thereon whose surface has been coated with fluoropolymers, characterized in that the fluoropolymers are introduced into the capillary system of the oxide ceramic layer in the form of a solution by vacuum impregnation, followed by removing the non-wetting portions of the solution and drying.

A coating composition comprising an aqueous mixture containing acid-stable particles and one or more fluoroacids. The amount of the acid-stable particles in the coating composition is from 0.005% to 8% by weight on a dry weight basis. The acid-stable particles can be selected from aluminum-modified silica particles, nonaluminum-modified silica particles, and organic particles selected from anionically stabilized polymer dispersion particles. The invention is also directed to a coating on a metal...

A coating composition comprising a reaction product of the following components: (a) at least one cyclic ether or anhydride; and (b) an alkoxysilane-functional polyacrylate, alkyd, polyester, epoxy, or a multifunctional polyol; and (c) at least one metal ester having the general formula Rm-M(OR')n, in which M is Si, Al, Zr, or Ti, Mg, B, W, or Mo, R is a hydrocarbon group of less than 10 carbon atoms or a group comprising hydrogen, carbon and oxygen of less than 20 carbon atoms, R' is an alkyl o...

A ski coating made from sintered PE contains fillers with raised thermal conductivity for improvement of the running characteristics. Additionally, additives are employed which possess melting temperatures in the region between -20.degree. C. and +10.degree. C.
