Abstract:
The present invention provides a flexible tube used for an endoscope and the like; an endoscopic medical apparatus that uses the flexible tube; and a resin composition for top coat layer used for the flexible tube. The flexible tube includes a flexible tube substrate that has a cylindrical shape and flexibility; a resin layer that covers the flexible tube substrate; and a top coat layer that covers the resin layer, in which the top coat layer contains a polymer compound derived from monomers including the following A to C. [A: hydroxyl group-free acrylate having a molecular weight equal to or greater than 110 €ƒ€ƒ€ƒ100 parts by mass] [B: hydroxyl group-free acrylate having a molecular weight equal to or greater than 80 and less than 110 €ƒ€ƒ€ƒ10 parts by mass to 200 parts by mass] [C: hydroxyalkyl acrylate €ƒ€ƒ€ƒ1 part by mass to 60 parts by mass]
Abstract:
The invention relates to methods for producing coatings on metal surfaces, in which a coating agent composition (K), applied to a metal surface that has been pre-coated if necessary, contains: a) at least one component (A) containing polyhydroxyl groups, b) at least one component (B) having on average at least one free and/or blocked isocyanate group and on average at least one hydrolysable silane group of formula (I) -N(X-SiR"x(OR')3-x)n(X'-SiR"y(OR')3-y)m (I), and d) at least one catalyst (D) containing phosphorous, for crosslinking silane groups, characterised in that i. the coating agent composition (K) is applied to wheel rims, ii. in component (B), 5 to 50 mol.% of the isocyanate groups originally present are converted to silane groups of formula (I), and iii. the phosphorous-containing catalyst (D) is selected from the group consisting of phosphorous-containing acids and/or partial esters of phosphorous-containing acids. The invention also relates to coatings obtainable with this method, and to the use of same.
Abstract:
The invention relates to a two-component coating composition, comprising (1) a base-lacquer component, comprising (A) at least one polycarbonate diol, (B) at least one hydroxyl-group-containing acrylate resin, polyester resin, and/or polyester-acrylate resin having a hydroxyl value of 75 to 500 mg KOH/g, and (C) at least one filler modified with at least one organosilane, and (2) a hardener component, comprising (D) at least one organic polyisocyanate, wherein the coating composition has a viscosity of 50 to 2000 m Pa∙s under a shear load of 1000 1/s and at a temperature of 23°C and has a fraction of organic solvents of 100 to 350 g/l.
Abstract:
The present invention relates to non-aqueous coating material compositions containing (A) at least one polyhydroxyl group-containing component (A); (B1) at least one isocyanate and silane group-containing component (B1); and (D) at least one catalyst (D) for the cross-linking of silane groups, characterized in that they (B2) comprise at least one isocyanate group-containing component (B2) which is different from component (B1) and comprises in addition at least one perfluoroalkyl group of the formula (I) CR 1 3 -(CR 2 2 ) f -, wherein R 1 , R 2 are independently from one another H, F and/or CF 3 , but R 1 and R 2 cannot be simultaneously H, and f = 1 to 20, preferably f = 3 to 11, particularly preferably f = 5 to 7. The invention further relates to coatings produced from these coating material compositions and the use thereof.
