    摘要: Adhesives for use on user-to-mask interfaces of a respiratory mask and methods of preparing the same are provided. The adhesive includes greater than or equal to about 1 wt. % to less than or equal to about 15 wt. % of one or more glycerides; greater than or equal to about 0.50 wt. % to less than or equal to about 5 wt. % of one or more polyacrylates; greater than or equal to about 1 wt. % to less than or equal to about 10 wt. % of one or more polyethers; greater than or equal to about 25 wt. % to less than or equal to about 45 wt. % of one or more N-vinylpyrrolidone polymers; and a balance of water. The method includes forming a first aqueous mixture, forming a second aqueous mixture, and admixing the first aqueous mixture and the second aqueous mixture to form a substantially homogeneous mixture that defines the adhesive.
