Abstract: The present invention relates to an UV-curable adhesive composition comprising a) from 35 to 45% by weight of the total weight of the composition of a difunctional epoxy acrylate oligomer; b) a difunctional acrylate monomer; c) from 2 to 7% by weight of the total weight of the composition of a bridged difunctional acrylate monomer; d) an adhesion promoter; e) a stabiliser; f) a defoamer; and g) a photoinitiator. The composition can be used in a radio frequency identification transponder.

Abstract: The present invention relates to an anaerobic curable composition comprising a) a (meth) acrylate component; b) a first curing agent; c) a second curing agent; and d) a cure accelerator comprising 2-(N-ethylanilino) ethanol and/or 1,2,3,4-tetrahydro benzo(H) quinoline-3-ol. The anaerobic curable composition according to present invention can be used in adhesives, sealants, thread lockers and retainers.

Abstract: The present invention provides an one-component (1K) anaerobic curable composition comprising, based on the weight of the composition: from 15 to 35 wt. % of a1) at least one (meth)acrylate monomer represented by Formula I: H2C?CGCO2R1??(I) wherein: G is hydrogen, halogen or a C1-C4 alkyl group; and, R1 is selected from C1-C30 alkyl, C3-C30 cycloalkyl, C2-C20 alkenyl and C2-C12 alkynyl; from 5 to 25 wt. % of a2) at least one (meth)acrylate monomer represented by Formula II: H2C?CQCO2R2??(II) wherein: Q may be hydrogen, halogen or a C1-C4 alkyl group; and, R2 may be selected from C6-C18 aryl, alkaryl and aralkyl; from 35 to 75 wt. % of a3) at least one (meth)acrylate-functionalized oligomer; from 0.1 to 10 wt. % of b) at least one cure initiator; from 0.1 to 5 wt. % of c) at least one cure accelerator; from 1 to 5 wt. % of d) at least one cellulose mixed ester of which all of said ester groups are selected from C1-C6 ester groups; and, from 1 to 5 wt. % of e) fumed silica.
