  • Publication number: 20070154643
    Abstract: Solid extrusion coating compositions for metal substrates, a method of extrusion coating a metal substrate, and a metal article are disclosed. The extrusion coating composition is a thermoplastic material and comprises: (a) a polyester having a weight average molecular weight of about 10,000 to about 50,000, and optionally, (b) a modifying resin, such as an epoxy resin having an epoxy equivalent weight of about 500 to about 15,000. The extrusion coating composition is applied to a metal substrate in an extrusion process to provide a composition film having a thickness of about 1 to about 40 microns.

  • Publication number: 20050154081
    Abstract: Polymerizable compositions are described containing colored polymerization indicators which confer a visible color on the unpolymerized compositions. Upon polymerization, the compositions exhibit reduced or eliminated color. The compositions can also change their opacity during polymerization. The compositions provide easy visual differentiation between the unpolymerized compositions and substrates on which the compositions are placed. The compositions are useful in clinical and laboratory applications such as those involving teeth, dental implants, orthodontic materials, artificial teeth and bones.

  • Patent number: 6709271
    Abstract: Dental composite compositions, restorative compositions, and methods for their use are provided. The compositions can contain (a) from about 1 to about 35 weight percent of a monomer portion containing at least one monomer having a functional group capable of undergoing polymerization; (b) from about 75 to about 95 weight percent of a filler portion, the filler portion containing at least a spherical filler portion having at least one spherical filler particle component; and (c) from about 0.01 to about 10 weight percent of a polymerization catalyst portion containing at least one catalyst capable of assisting in the polymerization of the functional group of the monomer portion and hardening of the composite after application of the composite to a tooth surface or other dental surface. The spherical filler portion is present in an amount sufficient to reduce shrinkage of the composite after polymerization to about 1.8 percent or less.
