Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.

The invention relates to a process for selectively treating parts of the surface of a porous dental zirconia article, the process comprising the steps of providing a liquid composition and a porous 3-dimensional dental zirconia article having an outer and inner surface, applying the liquid composition to only a part the outer surface and/or inner surface of the porous dental zirconia article, the liquid composition comprising a whitening agent comprising a phosphorous containing component, the phosphorous containing component comprising a phosphate, phosphone or phosphine moiety, with the proviso that at least one P-O unit of the phosphate, phosphone or phosphine moiety is dissociable or able to otherwise interact with zirconia.

The invention also relates to a dental zirconia article obtainable or obtained by such a process and a kit of parts comprising a container containing a certain liquid composition and a dental zirconia mill blank useful for producing a porous dental zirconia article.

This coated metal sheet for exterior covering has a metal sheet and a top coating layer disposed on the metal sheet, the top coating layer is configured from a fluororesin and contains a gloss control agent comprising 0.01-15 vol % of microporous particles and a matte agent comprising primary particles, and the coated metal sheet satisfies the belowmentioned formulae. In the number-based particle size distribution of the gloss control agent and the matte agent, R is the number average particle size (m) of the gloss control agent, D1.sub.97.5 and D2.sub.97.5 represent the 97.5% particle size (m) of the gloss control agent and the matte agent, Ru is the upper limit particle size (m) of the gloss control agent, and T is the top coating layer thickness (m).

There is described a low number average molecular weight (M.sub.N<10 kD) and high glass transition temperature (>75 C.) copolymer (optionally a solid grade oligomer (SGO)) that comprises (a) at least 20 wt-% of itaconate functional monomer(s), (b) not more than 40% of a hydrophilic monomer, preferably an acid functional monomer(s) in an amount sufficient to achieve an acid value from 65 to 325 mg KOH per g of solid polymer; (c) optionally not more than 70% of other monomers not being either (a) or (b), having a max content of vinyl aromatic monomer(s) of 40 wt-% and/or max content of methacrylate(s) of 40 wt-%; where the weight percentages of monomers (a), (b) and (c) are calculated as a proportion of the total amount of monomers in the copolymer being 100%.

A disposable toothbrush having a toothpaste composition distributed over the bristles of the toothbrush without the use of metal graft initiators and catalysts, and in which the toothpaste and the flavoring is maintained for an extended period of time.

A method of manufacturing a natural composite material multilayer structure includes: manufacturing a felt layer; spraying a thermosetting resin onto one surface or both surfaces of the felt layer; forming an intermediate layer of the sprayed thermosetting resin to form a composite material; heat-pressing the composite material through a heated mold; and cold-pressing the heat-compressed composite material.

A liquid polymeric coating composition that upon application to a substrate, such as a coil substrate, preferably does not exhibit the edge build and edge blistering that commonly occurs with conventional liquid polymeric coating compositions. In some embodiments, the liquid polymeric coating composition is modified by tailoring the surface tension, the openness of the coating composition as indicated by the modulus of elasticity, or a combination thereof to reduce edge build and edge blistering.
