The present application discloses novel self-polishing antifouling paint compositions comprising : 30-80 % by solids volume of the paint composition of a binder phase; 20-70 % by solids volume of the paint composition of a pigment phase, said pigment phase including solid particles consisting of one or more rosin constituents (e.g. rosin, rosin derivatives or rosin-modified polymers) entrapped or encapsulated in a matrix (e.g. a silica such as a silica aerogel); and optionally one or more solvents. The application further discloses a) a method for the preparation of the self-polishing antifouling paint composition, comprising bringing solid particles consisting of one or more rosin constituents entrapped or encapsulated in a matrix in admixture with a binder system and one or more constituents selected from dyes, additives, solvents, pigments, fillers, fibres and anti-fouling agents, and any other suitable constituents to be included in either the binder phase or the pigment phase of paint compositions; b) a method for providing a self-polishing effect of a paint composition, the method comprising the step of incorporating into the paint composition the solid particles; and c) a marine structure. |
