Abstract
This invention relates to a fast-dry pre-applied adhesive composition comprising at least one (meth)acrylate component; at least one accelerator; at least one organic peroxide; at least one non-aromatic epoxy resin; and at least one cationic photoinitiator. The weight ratio between the (meth)acrylate component and the non-aromatic epoxy resin is from 1:4 to 4:1. The pre-applied adhesive composition of the present invention is firstly coated onto a surface of a substrate and dried with the assistance of UV light. The dried pre-applied adhesive composition is later anaerobically cured after the coated substrate is assembled with the mating substrates and provides excellent thread locking strength and lap shear strength for bonding.
