[0180] Determination of viscosity of polymer solutions

[0181] The viscosity of the polymers was measured according to ASTM D2196-10 at 12 rpm using a Brookfield DV-I Viscometer with LV-2 or LV-4 axis. The polymer was tempered to 23.0°C ± 0.5°C prior to measurement.

[0182] Determination of solids content of polymer solutions

[0183] The solids content in the polymer solution is determined according to ISO 3251:2008. A 0.6g ± 0.1g sample was removed and dried in a ventilated oven at 150°C for 30 minutes. The weight of the remaining material is considered as non-volatile matter (NVM). The non-volatile content is expressed in weight percent. The values ​​given are the average of three replicates.

[0184] Determination of average molecular weight distribution of polymers

[0185] The polymers were characterized by gel permeation chromatography (GPC) measurements. Molecular weight distribution (MWD) was determined using a Polymer Laboratories PL-GPC50 instrument fr...

Abstract

A binder for a marine antifouling coating composition comprising a polyoxalate polymer having a Mw of at least 4000 g / mol, wherein the polyoxalate polymer comprises (i) oxalate monomer residues , the oxalate monomer is selected from oxalic acid or its diester derivatives, (ii) a second monomer residue, the second monomer is selected from a cyclic diester or a cyclic diacid; and (iii) A third monomer residue, the third monomer is hydrogenated bisphenol A.

Description

technical field [0001] The present invention relates to a marine antifouling coating composition, more particularly to a marine antifouling coating composition comprising a specific polyoxalate-like binder and the binder itself. The present invention also relates to a kit for preparing an antifouling coating composition or a "one-pot" antifouling coating composition comprising the novel polyoxalate binder. The invention also relates to surfaces coated with antifouling coating compositions. Background technique [0002] Surfaces submerged in seawater are contaminated by marine organisms such as green and brown algae, barnacles, mussels, tube worms, etc. For marine structures, such as ships, oil platforms, buoys, etc., such pollution is undesirable and has economic consequences. Contamination can lead to biodegradation of surfaces, increased loading and accelerated corrosion. Pollution on a ship will increase frictional drag, which will result in reduced speed and / or increa...
