Abstract
An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The adhesive composition is essentially solventless and capable of application in a hot melt process while maintaining stability at elevated temperatures in the range of 275° F. to 350° F., which not only allows hot melt application, but allows for ethylene oxide sterilization under heat stress.
Claims21
A hot melt adhesive composition having antimicrobial properties for skin contact applications comprising:
- a. an acrylic polymer;
- and
- b. an effective amount of diiodomethyl-p-tolylsulfone dispersed throughout said polymer.
A hot melt adhesive composition having antimicrobial properties comprising:
- a. an essentially 100% solids acrylic polymer for hot melt application;
- and
- b. an effective amount of diiodomethyl-p-tolylsulfone dispersed throughout said acrylic polymer.
A surgical drape comprising:
- a. a sheet of polymeric substrate;
- b. a coating of an adhesive composition overlying said polymeric substrate wherein said adhesive composition is hot melt applied to said substrate and includes an acrylic polymer having an effective amount of diiodomethyl-p-tolylsulfone dispersed throughout said adhesive composition.
