A process for biocidally finishing plastic materials selected from the group consisting of polyolefin, polystyrene, a halogen-containing polymer, polyacrylate or polymethacrylate, a polymer derived from unsaturated alcohols and amines or from their acyl derivatives or acetals, a homo- or copolymer of cyclic ethers, polyacetal, polyphenylene oxide or polyphenylene sulfide, polyurethane, polyamide or copolyamide, saturated or unsaturated polyester, polycarbonate, a phenol-formaldehyde resin, an epoxy resin or an aminoplastic resin, which process comprises adding a) either during the processing of the plastic materials or, b) in the case of plastic materials prepared via a radical polymerisation, already during the polymerisation or during the processing or, c) in the case of duroplasts prepared from a phenol-formaldehyde resin, epoxy resin or an aminoplastic resin, during the crosslinking reaction, at least one compound selected from the group consisting of 2-methylthio-4- cyclopropyl- amino-6-(.alpha., .beta.-dimethylpropylamino)-s-triazine, 2-methylthio-4- cyclopropylamino-6-tert-butyl- amino-s-triazine, 2-methylthio-4-ethylamino-6-tert-butylamino-s-triazine and 2- methylthio-4- ethylamino-6-(.alpha., .beta.-dimethylpropylamino)-s-triazine.
