Abstract
An applicator brush for use in connection with a moisture-responsive adhesive, such as a cyanoacrylate adhesive, is made with bristles constructed of filaments of a synthetic polymeric material and treated by fluorination to provide a surface barrier against the permeation of the bristles by moisture. The applicator brush is furnished in an adhesive package in which bristles of the brush are in contact with adhesive carried in a reservoir of a container of the package.
Claims12
In an applicator brush for use in connection with a moisture-responsive adhesive, the applicator brush having bristles with external surfaces for contacting the adhesive, an improvement wherein the bristles are constructed of filaments of a synthetic polymeric material treated by fluorination to establish a surface barrier along the external surfaces of the bristles for rendering the external surfaces resistant to permeation by moisture.
In a method for making an applicator brush for use in connection with a moisture-responsive adhesive, the applicator brush having bristles with external surfaces for contacting the adhesive, an improvement comprising the steps of:
- constructing the bristles of filaments of a synthetic polymeric material;
- and
- treating the material of the bristles by fluorination to establish a surface barrier along the external surfaces of the bristles for rendering the external surfaces resistant to permeation by moisture.
In an adhesive package for use in connection with a moisture-responsive adhesive, the adhesive package including a container for the adhesive and an applicator brush for extending into the container to be in contact with the adhesive in the container, the applicator brush having bristles with external surfaces for contacting the adhesive, an improvement wherein the bristles are constructed of filaments of a synthetic polymeric material treated by fluorination to establish a surface barrier along the external surfaces of the bristles for rendering the external surfaces resistant to permeation by moisture.
