Embodiment Construction

[0009] The sizing compositions of the present invention are prepared by combining the low VOC silane / hydrolyzate of the present invention with a liquid carrier. The carrier may include water, in which case the low VOC silane will hydrolyze to silicon-containing hydrolyzate without producing any significant amount of volatile organic compound by-products. Alternatively, the sizing composition may be non-aqueous, in which case the carrier may be an organic compound in which the silane is applied to the fibers in an initially non-hydrolyzed or partially hydrolyzed state, after application to the fibers to achieve complete of hydrolysis.

[0010] Organic compounds suitable for use as carriers in the sizing compositions of the present invention include, but are not limited to, linear and branched aliphatic and aromatic hydrocarbons, ethers, amorphous and microcrystalline waxes, polycaprolactones, and Aprotic solvent for methyl formamide and 1-methyl-2-pyrrolidone. The sizing comp...

Abstract

A low VOC sizing composition includes a liquid carrier containing a silane which, upon hydrolysis, produces substantially no significant amount of volatile organic compound and / or the silicon-containing hydrolyzate of the silane. The sizing composition can optionally include one or more of film forming agents, anti-static agents, lubricants, surfactants, emulsifying agents, wetting agents, peroxide, starch, oil, plasticizer, wax, acids or bases.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 60 / 651,025, filed February 8, 2005, which is incorporated herein by reference. Background of the invention [0003] The use of alkoxy-functional silanes in the sizing formulations used during the manufacture of glass fibers leads to the release of alcohols upon hydrolysis of the silanes. The alcohol, usually methanol or ethanol, can pose air quality and worker safety concerns. Due to increasingly stringent VOC emission controls, fiberglass manufacturers have repeatedly been forced to reduce production, install recovery or treatment equipment, or reformulate compounds to meet new, more stringent emission limits. Fiberglass producers need to find more cost-effective ways to reduce volatile organic compound (VOCs) emissions from their size tank formulations. [0004] Sized fiber bundles are used to reinforce thermoplastic and thermoset polymer mater...
