ONE PART, FAST-SETTING, AQUEOUS ADHESIVE EMULSIONS

摘要

The present disclosure relates to acrylic adhesive emulsions comprising a core-shell polymeric component comprising an inner core and an outer shell containing at least one pendent functional group; a polyfunctional component capable of reacting with at least one of the pendent functional groups on the outer shell; wherein the inner core is free of functional groups reactive with the pendent functional groups on the outer shell; and wherein the pH of the emulsion is 6.5 or less; and wherein the emulsion is a fast-setting, one part, aqueous, adhesive. Bonded articles made therefrom, and methods of bonding articles using these emulsions are also disclosed.

主权项

1. An emulsion comprising:
a) a core-shell polymeric component comprising:
i. an inner core comprising a (meth)acrylate copolymer having a first glass transition temperature, andii. an outer shell comprising a (meth)acrylate copolymer containing at least one pendent functional group and having a second glass transition temperature which is less than, or equal to, the first glass transition temperature; b) a polyfunctional component capable of reacting with at least one of the pendent functional groups on the outer shell; wherein the inner core is free of functional groups reactive with the pendent functional groups on the outer shell; and wherein the pH of the emulsion is 6.5 or less; and wherein the emulsion is a fast-setting, one part, aqueous, adhesive.
