Abstract
An adhesive formulation may include a functionalized polyolefin having a polyolefin backbone with a molecular weight in a range from 60,000 Da to 90,000 Da, and a solvent or a solvent mixture present in a range from 52 wt % to 82 wt %. The polyolefin backbone is functionalized by addition of a polar side chain to the polyolefin backbone.
Claims20
An adhesive formulation comprising:
- a functionalized polyolefin having a polyolefin backbone with a molecular weight in a range from 60,000 Da to 90,000 Da;
- and
- a solvent or a solvent mixture present in a range from 52 wt % to 82 wt %.
A method of bonding a first material to a second, dissimilar material, the method comprising:
- applying an adhesive formulation to a surface of one or both of the first and second materials, the adhesive formulation comprising:
- a functionalized polyolefin having a polyolefin backbone with a molecular weight in a range from 60,000 Da to 90,000 Da, and
- a solvent or a solvent mixture present in a range from 52 wt % to 82 wt %;
- and
- bonding the first material to the second material.

A method of bonding a first material to a second material, the method comprising:
- applying an adhesive formulation to a surface of one or both of the first and second materials;
- and
- bonding the first material to the second material,
- wherein the first material is a low surface energy non-PVC substrate material,
- wherein the second material is a rigid polymer selected from the group consisting of polycarbonate, polyester, acrylic, polystyrene, acrylonitrile butadiene styrene (ABS), and methyl methacrylate ABS, and
- wherein the adhesive formulation comprises:
- a functionalized polyolefin, the functionalization including addition of a polar side chain to a polyolefin backbone, and
- a solvent or a solvent mixture.
