[0155] Analysis steps

[0156] Determining the solids content of polymer solutions

[0157] The solids content in the polymer solution is determined according to ISO3251. A test sample of 0.6g±0.1g was taken out and dried in a ventilated oven at 150°C for 30 minutes. The weight of residual material is considered as non-volatile matter (NVM). The non-volatile matter content is represented by weight percentage. Values ​​given are the mean of three parallel groups.

[0158] Determination of average molecular weight distribution of polymers

[0159] The polymers were characterized by gel permeation chromatography (GPC). Tetrahydrofuran (THF) was used as the eluent at room temperature, a constant flow rate of 1 mL / min, using a PL-GPC 50 instrument from Polymer Labs and two 5 μm PL silica gel mixed D columns from Polymer Labs, and the refractive index ( RI) detectors are connected in series to determine the ...

Abstract

An antifouling coating composition comprising: (I) a binder component comprising at least one hydrolysable copolymer and at least one hydrocarbon resin wherein the total amount of hydrocarbon resin forms 1 to 50 wt% of the binder component (I); and (II) at least one an antifouling agent; wherein said hydrocarbon resin comprises a resin formed by the polymerisation of at least one monomer selected from a C5 aliphatic monomer, a C9 aromatic monomer, an indene coumarone monomer, or a terpene.

Description

technical field [0001] The present invention relates to an antifouling coating containing hydrocarbon resin and its use in improving the performance of said antifouling coating. Background technique [0002] Surfaces submerged in seawater are contaminated with marine organisms such as green and brown algae, barnacles, mussels, tubeworms, and the like. Such pollution is undesirable and has economic consequences for marine structures such as ships, oil platforms, buoys, etc. This contamination can lead to biodegradation of the surface, increased loading and accelerated corrosion. Pollution on board ships increases frictional drag, which will result in reduced speed and / or increased fuel consumption. It may also result in reduced handling performance. [0003] Antifouling coatings are used to prevent subsidence and the growth of marine life. These coatings usually contain a film-forming binder, together with various components such as pigments, fillers, solvents and bioacti...
