An anaerobically curable composition comprises a hydroxy-functionalised mono(meth)acrylate, an aromatic mono(meth)acrylate that is not hydroxy-functionalised, a (meth)acrylate-functionalised polyurethane, and an anaerobic cure-inducing component. The composition may comprise 5-30 wt.% hydroxy-functionalised mono(meth)acrylate (e.g. hydroxyethyl methacrylate), 5-60 wt.% aromatic mono(meth)acrylate (e.g. benzyl methacrylate), 20-50 wt.% (meth)acrylate-functionalised polyurethane, and 5-15 wt.% polyethylene filler. The composition may be thixotropic with a viscosity of 500-3000 mPa.s and may comprise hydrophobic silica. Preferably, the molecular weights of the hydroxy-functionalised mono(meth)acrylate, the aromatic mono(meth)acrylate, and the polyurethane are 100-150 g/mol, 150-200 g/mol, and 5000-7000 g/mol, respectively. A method of sealing a joint between male and female mating parts comprises applying the composition to at least one mating part, joining the mating parts to form a joint ...

An anaerobically curable composition, such as a one-part adhesive, comprises a (meth)acrylate monomer, a redox-active metal catalyst, saccharin, a peroxide, and a benzoyl-functionalised compound, wherein the composition does not gel after 24 hours of storage at room temperature. The composition may contain an oligomeric polymerisable (meth)acrylate monomer and an amine, e.g. a secondary aromatic amine. The (meth)acrylate monomer is preferably triethylene glycol dimethacrylate or polyethylene glycol dimethacrylate. The catalyst may be iron (II) naphthenate, copper disodium ethylenediamine tetraacetic acid (EDTA.2Na.Cu(II)), copper naphthenate, vanadium acetylacetonate, vanadyl acetylacetonate, or iron (II) acetate. The benzoyl compound is typically a photoinitiator. Preferably, the composition comprises 10-90 wt.% (meth)acrylate monomer, 0.0001-2 wt.% catalyst, 0.1-2 wt.% saccharin, 0.5-10 wt.% peroxide, and 0.1-5 wt.% benzoyl compound.
