Abstract
Embodiments of the present disclosure relate to adhesive compositions containing an adhesive resin and a crosslinkable component. The novel compositions can exhibit synergistic improvements in parameters such as modulus, overlap shear strength, shelf life, and others.
Claims20
An adhesive composition comprising:
- a. a pressure sensitive adhesive resin;
- b. a first crosslinkable component;
- and
- c. a second crosslinkable component,
- wherein the first crosslinkable component has a greater weight percentage in the composition than the second crosslinkable component, based on the total weight of the composition,
- wherein the first crosslinkable component is different than the second crosslinkable component, and
- wherein the second crosslinkable component has a lower cure temperature than the first crosslinkable component.

An adhesive composition comprising:
- a. an acrylic based pressure sensitive adhesive resin;
- and
- b. a first crosslinkable component comprising diallyl orthophthalate in an amount of at least about 5 wt %, based on the total dry weight of the adhesive composition.
An adhesive composition comprising:
- a. a pressure sensitive adhesive resin;
