Abstract
The present application provides compositions and methods for allowing surfaces such as HDPE, LDPE, polyethylene, polypropylene, Teflon (polytetrafluoroethylene), SBS, SEBS, SIS elastomers, and silicone rubber, which are notoriously difficult to apply adhesives, glues, or coatings to, to be treated with a Primer System comprising a cyanoacrylate monomer and non-polar solvent component and an initiator component, wherein the polymerization product of the components is a microstructured polycyanoacrylate layer. The microstructured polycyanoacrylate layer-increases the ability of a glue, adhesive, or coating to adhere to that surface and subsequently allows other materials to be used as coatings on the surface or to be applied using a glue or adhesive.
Claims18
A primer system for making a surface suitable for adhesion comprising:
- a primer A and a primer B;
- wherein primer A comprises an initiator chosen from Lewis bases, photo-initiators, free radical producing species, and anion-producing species;
- wherein primer B comprises at least one cyanoacrylate monomer and a non-polar solvent, the weight percentage of the at least one cyanoacrylate monomer relative to the entire primer B composition being less than 15% and greater than or equal to at least 0.5%;
- and
- wherein the polymerization of the at least one cyanoacrylate monomer of primer B by the initiator of primer A produces a xerogel that creates a microstructured polycyanoacrylate layer.
A composition comprising:
- primer A comprising an initiator chosen from Lewis bases, photo-initiators, free radical producing species, and anion-producing species;
- primer B comprising at least one cyanoacrylate monomer and a non-polar solvent, the weight percentage of the at least one cyanoacrylate monomer relative to the entire primer B composition being less than 15% and greater than or equal to at least 0.5%;
- and
- wherein the polymerization of the at least one cyanoacrylate monomer of primer B by the initiator of primer A produces a xerogel that creates a microstructured polycyanoacrylate layer.
A kit comprising a primer system comprising primer A and primer B;
- wherein the primer A comprises an initiator chosen from Lewis bases, photo-initiators, free radical producing species, and anion-producing species;
- primer B comprises at least one cyanoacrylate monomer and a non-polar solvent, the weight percentage of the at least one cyanoacrylate monomer relative to the entire primer B composition being less than 15% and greater than or equal to at least 0.5%;
- and
- wherein the polymerization of the at least one cyanoacrylate monomer of primer B by the initiator of primer A produces a xerogel that creates a microstructured polycyanoacrylate layer.
