PURPOSE:To obtain an attachment inhibitor, containing a quanternary ammonium compound and a higher aliphatic amine compound and effective in preventing materials from fouling with marine attaching organisms, especially Hydroides elegans Haswell. CONSTITUTION:An attachment inhibitor containing (A) a compound, e.g. cetyltrimethylammonium bromide expressed by formula I (R is 12-18C aliphatic hydrocarbon group; R<1> is methyl or 12-18C aliphatic hydrocarbon group; R<2> is methyl or benzyl; R<3> is methyl; all R<1> to R<3> may be pyridine or picolyl through N, except that both R<1> and R<2> are simultaneously aliphatic hydrocarbon group and benzyl; X is acid residue) and (B) a compound expressed by formula II [R<4> is 12-18C aliphatic hydrocarbon group; R<5> is H or methyl; R<6> is H, methyl, -(CH2)2-NH2 or -(CH2)3-NH2 (provided that R<6> is methyl when R<5> is methyl)] or its acid addition salt, e.g. tetradecylamine hydrochloride in an amount of 0.1-8 pts.wt., preferably 0.2-5 pts.wt. based on 1 pt.wt. ingredient (A). |
