摘要:
The present invention relates to a coating composition comprising at least one binder (A) comprising at least one polymeric resin (A1) and at least one crosslinking agent (A2), at least one anticorrosion pigment (B), and at least one organic solvent (C), where (B) is an alloy of Zn and Mg and optionally at least one further metal and/or semimetal, the coating composition having a pigment volume concentration (PVC) in a range from 5.0% to 25.0%, and comprising the anticorrosion pigment (B) in an amount in a range from 5.0 to 25.0 wt%, based on the total weight of the coating composition, to the use thereof for the at least partial coating of a metallic substrate with a primer coat, to a method for the at least partial coating of such a substrate with such a primer coat, to a substrate at least partially coated therewith, and to a component or article produced from such a substrate.

The invention relates to the use of biodegradable plastic films as vacuum films in methods for producing fiber-reinforced plastics or fiber-reinforced plastic components by means of vacuum infusion. The invention further relates to a method for producing fiber-reinforced plastics or fiber-reinforced plastic components, in particular fiber-reinforced rotor blades for wind turbines, by means of vacuum infusion using biodegradable films.
摘要:
The invention relates to a composition that contains at least one polyol component containing 3 to 15 wt % OH groups relative to the total weight of the polyol component and at least one isocyanate component containing 5 to 15 wt % isocyanate groups relative to the total weight of the isocyanate component. The polyol component contains at least one polyurethane prepolymer containing OH groups. The isocyanate component contains at least one diisocyanate- or polyisocyanate-terminated polylactone prepolymer. The composition can be used as an erosion-resistant coating agent.

The invention relates to a composition which comprises at least one polyol component having a hydroxyl group content of 9% to 15% by weight relative to the total weight of the polyol component, and at least one isocyanate component having a free isocyanate group content of 10% to 15% by weight relative to the total weight of the isocyanate component. The polyol component comprises at least one polyol which is selected from the group of the polyether polyols, polyester polyols, and polyether polyester polyols. The isocyanate component comprises at least one di‑ or polyisocyanate-terminated polylactone prepolymer. The composition can be used as erosion-resistant coating material.
摘要:
The present invention relates to fiber-plastic composites consisting of (I) at least one fiber material and (II) a plastic matrix, wherein the composite is characterized in that the plastic matrix is based on a two-component matrix material (IIa), the two-component matrix material (IIa) (1) comprising a stem component comprising (A) at least one polycarbonate diol and (2) a hardener component comprising (C) at least one polyisocyanate-modified polyester having an isocyanate content of 4 to 15 %. The present invention also relates to a method for producing the fiber-plastic composites and to the use thereof.
