The present invention is directed to a coated conduit comprising: a) a conduit having an interior and exterior surface; and b) a cured coating formed from a reaction mixture that is applied to at least one surface of the conduit. The reaction mixture comprises: i) a filler material comprising fibers ranging in length from 0.1 to 15.54 cm and having an aspect ratio of at least 5; and ii) a reactive component that demonstrates a tack-free time of less than five minutes at a temperature of 20 to 25&#xb0; C. The present invention is also directed to a method of repairing or reinforcing a conduit, comprising: (a) applying a curable coating composition to at least one surface of the conduit, wherein the curable coating composition is formed from the reaction mixture described above; and (b) allowing the curable coating composition to at least partially cure by exposing the composition to ambient conditions.

Some embodiments of the present invention provide fiberizable glass compositions formed from batch compositions comprising amounts of one or more glassy minerals, including perlite and/or pumice. Some embodiments of the present invention related to glass fibers formed from such batch compositions, and composites and other materials incorporating such glass fibers.

Glass compositions and fibers made therefrom

Embodiments of the present invention provides fiberizable glass compositions formed from batch compositions comprising amounts of one or more glassy minerals, including perlite and/or pumice.

Methods to make glass compositions and fibers made therefrom

Embodiments of the present invention provides fiberizable glass compositions formed from batch compositions comprising significant amounts of one or more glassy minerals, including perlite and/or pumice.

In some embodiments, the present invention provide filtration media for the treatment of flue gas streams and methods of making and using the same. In one embodiment, a filtration medium comprises a pollutant absorbent layer comprising a plurality of activated carbon fibers, at least one woven fabric, and at least one non-woven fabric, wherein the pollutant absorbent layer is positioned between the at least one woven fabric and the at least one non-woven fabric.

Filtration media and applications thereof

Chemically treated glass fibers having good processability are useful in producing fiber reinforced polymeric matrices, wherein the glass fibers have controlled wettability and are not detrimental to the weatherability of the fiber reinforced polymeric matrices. The chemically treated fibers have the dried residue of an aqueous chemical treating composition having a bisphenol A polyester film forming polymer compatible with and soluble in the matrix polymer, poly(vinyl acetate) polymeric film former, acryloxy-containing or methacryloxy-containing organo coupling agent in an effective coupling agent amount, cationic fiberous lubricant in an effective lubricating amount, with or without a cationic organic quaternary ammonium salt having alkoxy moieties, and with water in an amount to give a total solid for the aqueous chemical treating composition in the range of about 1 to about 30 weight percent. In addition, the aqueous chemical treating composition can have one or more amino-containing organofunctional silane coupling agents. The amount of the organic quaternary ammonium agent generally is in the range of from 0.05 to around 0.4 weight percent of the aqueous chemical treating composition. When this agent is not in the aqueous chemical treating composition, a secondary application of an antistatic agent is performed. The chemically treated glass fibers can be produced in any form such as chopped strand or continuous strand for combination with polymeric matrices including both filled and unfilled systems for producing reinforced polymeric matrices such as glass fiber reinforced polymeric panels which can be clear, translucent or pigmented.
