Composition with controlled release of biocidal metal ions

摘要: A thermoplastic composition containing the following components: I. 40 to 95 wt .-% of a polymer, II. 5 through 60 core-shell particles whose shell consists essentially particulate silica having thickness 0.1 10 micrometers and core at least one antifouling metal oxide in spherical / or spheroidal form number average particle diameter 1 20 microns is present, III. 0 30 additives commonly used, can be used for coating substrate. In order release selectively adjustable controllable.
