Plastics bonding systems and methods

A method for bonding a first substrate formed of a plastic material to a second substrate, wherein the first substrate comprises a reaction initiator incorporated into the first substrate, the method comprising:

• a) providing a reactive component on the surface of the first substrate, the reactive component further comprising a carrier component;
• b) exposing the reactive component to the reaction initiator;
• and
• c) engaging at least a portion of the first substrate with the second substrate to create a bonding engagement;
• and
• wherein the reactive component comprises one or more members selected from the group consisting of a methylene malonate component, a methylene beta-ketoester component, a methylene beta-diketone component, and an oligomer or resin thereof;
• wherein the plastic material and the reaction initiator are different.

A kit comprising:

• a first substrate formed of a plastic material and comprising a reaction initiator, the reaction initiator incorporated into the first substrate;
• a second substrate;
• and
• a plastic bonding adhesive composition comprising a reactive component effective to bond the first substrate to the second substrate upon exposure to the reaction initiator and a carrier component, wherein the reactive component comprises one or more members selected from the group consisting of a methylene malonate component, a methylene beta-ketoester component, a methylene beta-diketone component, and an oligomer or resin thereof;
• and
• wherein the plastic material and the reaction initiator are different.
