The present invention provides a method for crosslinking an acrylic emulsion with a (meth)acrylate monomer or a (meth)acrylate oligomer including adding a base acrylic emulsion to a vessel, adding at least one (meth)acrylate crosslinker to the vessel, incorporating the at least one (meth)acrylate crosslinker into the base acrylic emulsion to create a two-phase system including water and a phase including crosslinkers of the at least one (meth)acrylate crosslinker inside acrylic emulsion particles of the base acrylic emulsion, applying the two-phase system to a surface, and curing the two-phase system to create a final system including a continuous film and crosslinked crosslinkers.

Small-radius coated optical fibers having large mode field diameter and low bending losses. The coated fiber may have an outer radius of 110 μm or less, while providing a mode field diameter of 9.0 μm or greater and a bending loss when wrapped about a 15 mm mandrel of 0.5 dB/km or less at wavelength of 1550 nm. The coated fiber may have a mode field diameter of 9.2 μm or greater and may have a bending loss at 1550 nm of 0.25 dB/km or less when wrapped about a 20 mm mandrel or a bending loss at 1550 nm of 0.02 dB/km or less when wrapped about a 30 mm mandrel.

The present disclosure provides a composite material. The composite material includes 20 to 40 weight percent (wt. %) of a polymerizable component; 6 to 40 wt. % of ceramic fibers; and 30 to 70 wt. % of nanoclusters. Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.

The present disclosure provides two part, room-temperature curable hybrid epoxy/(meth)acrylate compositions, comprising: (a) a first component, comprising (meth)acrylate monomers, crosslinkers, epoxy curatives, and optional free radical accelerator, tougheners, fillers and additives, and inhibitors; and (b) a second component, comprising epoxy resins, methacrylate free radical initiators, and optional tougheners, fillers and additives.
