A UV light curable adhesive is disclosed, comprising, at least one bi-active monomer, at least one polymerizable oligomer, a primary photoinitiator, and a monomer scavenger, wherein photopolymerization of the at least one bi-active monomer by the primary photoinitiator activates the monomer scavenger, reducing residual monomer content in a cured adhesive formed by the photopolymerization of the bi-active monomer in comparison to an otherwise identical comparative UV adhesive lacking the monomer scavenger. A method for curing the UV light curable adhesive is disclosed, including applying the UV light curable adhesive to a surface and exposing the UV light curable adhesive to UV light, free from heating the UV light curable adhesive other than any autogenous increases in temperature from exothermic polymerization reactions. A device with the UV light cured adhesive is disclosed, including the UV light cured adhesive joining a first surface to a second surface.

A cure-on-demand adhesive kit capable of self-sustaining frontal polymerization after a heat or actinic radiation trigger for bonding two substrates is provided. The kit includes a first monomer/oligomer component and a UV or thermal cure catalyst component. In practical application, the first monomer/oligomer component and the UV or thermal cure catalyst component are mixed together to form a ready-to-use prepolymer mixture. The prepolymer mixture is applied onto the surface of a first substrate, and the first substrate is contacted with a second substrate by the mixture applied side. After giving a heat or actinic radiation trigger, a self-sustaining frontal polymerization of the mixture will be started for curing the mixture between two substrates as an adhesive to adhere the two substrates.
