Embodiment Construction

[0145] figure 1 A top view of the surface coating 10 is shown. The surface coating 10 is particularly useful for parts in aquatic applications, for example as an antifouling coating.

[0146] It can be seen that the surface coating 10 has a composition 12 which is separately formed or has a polymer structure. The polymer structure consists of three, ie at least three, units. where the first unit, not shown, comprises a polyamidoamine-based dendrimer structure, wherein the second unit 14 comprises an epoxy resin, and wherein the third unit 16 comprises an amine-reactive polysiloxane, in such a manner as To construct the polymer structure: the first unit is formed as a central unit to which each of the second unit 14 and the third unit 16 is covalently bonded.

[0147] in this regard, figure 1 A matrix 18 of epoxy resin of the second unit 16 is shown, in which there is a domain 20 of polysiloxane (eg, polydimethylsiloxane) of the third unit, which is connected to the ring ...

Abstract

The present invention relates to a composition (12) for a surface coating (10), in particular for aquatic applications, characterised in that the composition (12) has a polymer structure composed of at least three units, wherein a first unit comprises a dendrimer structure based on a polyamidoamine, a second unit (14) comprises an epoxy resin, and a third unit (16) comprises an amine-reactive polysiloxane, wherein the polymer structure is constructed such that the first unit is designed as a central unit to which the second unit (14) and the third unit (16) are each covalently bonded.

Description

technical field [0001] The invention relates to an antifouling coating. The invention also relates to a method for producing such an antifouling coating. Background technique [0002] Biofouling refers to the colonization of aquatic habitats on exposed surfaces by microorganisms (microfouling organisms) and larger organisms (macrofouling organisms). In order for larger organisms to permanently settle on a surface, the surface must first be gradually covered with a so-called conditioning membrane composed of organic material and successively colonized first by bacteria and fungal organisms and finally by macroorganisms. [0003] Biofouling can increase a ship's fuel consumption by up to 40%, costing an estimated €200 billion per year. It is estimated that NO caused by biofouling x 、So x , CO 2 The additional emissions of carbon dioxide and other toxic pollutants can kill as many as 60,000 people a year. This is described, for example, in the article Selim et al: Recent ...
