The present invention relates to aqueous-based compositions suitable for use in threadlocking applications comprising: a) at least one carboxyl group containing (co)polymer; b) at least one polymerizable monomer A containing one acryloyl group; c) at least one polymerizable compound B containing at least two acryloyl groups; d) at least one encapsulated free radical initiator; and e) water. The inventive aqueous-based compositions are preferably substantially free of volatile organic solvents. 1. An aqueous-based composition comprising:a) at least one carboxyl group containing (co)polymer;b) at least one polymerizable monomer A containing one acryloyl group;c) at least one polymerizable compound B containing at least two acryloyl groups;d) at least one encapsulated free radical initiator; ande) water.2. The aqueous-based composition according to claim 1 , being substantially free of volatile organic solvents.3. The aqueous-based composition according to claim 1 , wherein the carboxyl group containing (co)polymer is composed of 10 to 99 mole percentage of one or more carboxyl group containing ethylenically unsaturated monomer(s) claim 1 , and of 1 to 90 mole percentage of one or more ethylenically unsaturated monomer(s) claim 1 , which do not contain any carboxyl group.4. The aqueous-based composition according to claim 3 , wherein the carboxyl group containing ethylenically unsaturated monomer is selected from acrylic acid claim 3 , methacrylic acid claim 3 , crotonic acid claim 3 , itaconic acid claim 3 , fumaric acid claim 3 , maleic acid claim 3 , and citraconic acid the ethylenically unsaturated monomer claim 3 , which does not contain any carboxyl group claim 3 , is selected from vinyl aromatic compounds.6. The aqueous-based composition according to claim 1 , wherein the at least one polymerizable compound B is selected from acryloyl-containing polyesters claim 1 , acryloyl-containing polyurethanes claim 1 , alkoxylated acryloyl compounds and mixtures or ...
