Abstract
A dental floss having improved abrasion resistance composed of dental fibers coated with a UV-curable resin, and a method for producing a dental floss having improved abrasion resistance.
Claims14
A method of producing a dental floss coated with a UV-cured resin, comprising the steps of:
- a) preparing a coating composition containing a monomer having one or more cross-linkable functional groups, wherein said monomer is selected from the group consisting of epoxy acrylate, polyurethane acrylate, polyester acrylate, acrylic acrylate, epoxy methacrylate, polyurethane methacrylate, polyester methacrylate and acrylic methacrylate, and (b) a photoinitiating compound;
- b) coating a dental filament with the coating composition of step a);
- and
- c) exposing the coated filament from step b) to UV radiation to cause the coating composition to be cured to a desired degree of hardness;
- wherein, after step c), said coating composition is safe for use in the mouth.
2 more elements
A dental floss comprising:
- a filament coated with a cross-linked resin composition, the resin composition comprising, prior to cross-linking:
- a monomer that polymerizes and cross-links when exposed to ultraviolet light, and
- a photoinitiating compound.
An article comprising
- a filament coated with a resin comprising a monomer and a photoinitiating compound, wherein the monomer polymerizes and cross-links when exposed to ultraviolet light, providing a dental floss.
