摘要： The invention relates to a method of providing a seal between an aluminium substrate and a second substrate, wherein the seal is exposed to engine fluids selected from oils and/or coolant mixtures at elevated temperatures in the range from 600C to 175°C. The method of the invention involves (a) applying to at least one of the substrates an anaerobic sealant composition made from (i) one or more polymerizable (meth)acrylate ester monomers, (ii) an anaerobic cure- inducing component, and (iii) 0.05 to 0.25 % by weight, based on the total composition, of an adhesion promoter comprising one or more phosphorus-containing compounds having the general formula (I), wherein: R 1 is H, CH 3 or C 2 H 5 , R 2 is -CH 2 -C 2 H 4 TC 3 H 6 -, or -CH 2 -CH-(CH 3 )-, R 3 is H, CH 3 or C 2 H 5 , n is an integer from 1 to 10, and m is an integer from 1 to 3; (b) bringing the substrates together face-to-face with a gap between the faces in the range from 0.1 to 0.25 mm, in at least part of the total face-to-face area, and (c) allowing or enabling the composition to cure at substantially ambient temperature.
