Abstract: A sizing composition containing an epoxy resin emulsion, one or more coupling agents, a cationic lubricant, and an acid. The epoxy resin emulsion includes a low molecular weight epoxy and one or more surfactants. The epoxy resin has an epoxy equivalent weight of from 175-225, preferably from 175-190. Optionally, the sizing composition may also contain a non-ionic lubricant, a polyurethane film former, and/or an antistatic agent. The sizing composition may be used to size glass fibers used in filament winding applications to form reinforced composite articles with improved mechanical properties, wet tensile properties, improved resistance to cracking, and improved processing characteristics.

Abstract: Disclosed are a series of composite polymer composite structures formed by the coextrusion of at least two distinct polymeric components. A first polymeric component includes a structural composition and a second polymeric component includes a coating composition. The primary structural frame formed from the structural composition includes at least one longitudinal recess. These recesses may be filled with a third polymeric composition that may include wood byproducts and/or a blowing agent. The first polymeric component may include reinforcing fibers at least partially coated with a size composition that includes a film forming agent, a lubricant, one or more additives, and first and second coupling agents. The additives may be chosen to achieve selective or desired properties in the end product.

Abstract: Disclosed are a series of composite polymer composite structures formed by the coextrusion of at least two distinct polymeric compositions including a structural composition and a coating composition whereby the primary structural frame formed from the structural composition includes at least one, and typically a plurality, of longitudinal recesses or cavities. These recesses or cavities may, in turn, be filled with a third distinct polymeric composition that may include wood byproducts and/or a foaming or blowing agent.

Abstract: An insulation product that contains a Kraft paper facing treated with a combination of antimicrobial agents that imparts improved microbial resistance to the Kraft paper is provided. A preferred anti-microbial composition includes (1-[[2-(2,4-dichloropheyl)-4-propyl-1,3-diololan-2-yl]-methyl]-1H-1,2,4-triazole, ?-(2-(4-chlorphenyl)ethyl)-?-(1-1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol, and alkyl dimethylbenzyl ammonium saccharinate. The anti-microbial agents may each be present in the anti-microbial composition in an amount of from 50 to 1000 ppm. A biocide such as 2-(4-thiazolyl)benzimidazole may be added to the anti-microbial composition to impart additional microbial resistance. The Kraft paper may be adhered to the insulation by anti-microbially treated asphalt. The anti-microbial agent may be added to the asphalt in an amount of from 200-3000 ppm prior to applying the asphalt to the Kraft paper. In at least one exemplary embodiment, 2-n-octyl-4-isothiazolin-3-one is added to the asphalt.

Abstract: A formaldehyde free co-binder solution formed by using a polyol to crosslink polycarboxylic acid and a polyacid monomer is provided. In forming the co-binder solution, the polyacid monomer and the polyol are mixed in any conventional device with heat and agitation for a period of time sufficient for the chemicals to react and form a reaction product. The resultant product is then admixed with polycarboxylic acid to form a co-binder solution. In a preferred embodiment, the polyacid is maleic anhydride and the polyol is triethanolamine.
