Mineral wool insulation products are provided. The mineral wool insulation includes a plurality of mineral wool fibers and a wax emulsion applied to the mineral wool fibers. The wax emulsion imparts excellent water resistance and thermal performance properties to the mineral wool insulation.

The present invention provides modified urea formaldehyde (UF) resin binder compositions and mineral fiber mats having an emulsion polymer modifier comprising, in copolymerized form, from 5 to 25 wt. % of co polymerized carboxylic acid functional monomers. The emulsion polymers have a measured glass transition temperature (DSC) ranging from −40° C. to 70° C. and a large average particle size. Further, the emulsion polymers comprise less than 30% of the copolymerized acid in neutralized form and do not excessively thicken aqueous compositions containing them. The modified UF resin binder compositions enable good dilution stability in use and high tensile strength in products containing them.

Biocides for bio-based binder compositions are disclosed. Bio-based binders include those having a nutrient source such as carbohydrate, protein or fat, which can serve as an energy source for organisms to grow in areas that contact binder. Principal areas that contact bio-based binder in a fiberglass insulation manufacturing process include the raw ingredients, the binder chemicals, the prepared binder dispersions, the forming hood and related equipment, the final insulation product and, importantly, the cleaning systems and washwater arising from cleaning the manufacturing equipment and/or forming the product. Frequently the washwater is stored until re-cycled for re-use. Storage may take place in tanks, towers, vats and even outdoor reservoirs, all of which may harbor the growth of unwanted organisms, for which a biocide is desirable.

Provided is a binder that has satisfactory storage stability and can express an excellent bonding strength for a glass fiber or powdered glass (impart a satisfactory strength to a bonded body with the glass fiber or the powdered glass). The binder of the present invention includes: a polymer having a hydroxyl group; and an ammonium salt of an inorganic acid, in which: the polymer contains a specific structural unit derived from a monomer represented by the general formula (1) and a specific structural unit derived from a monomer containing a carboxylic acid (salt) group; a content of the structural unit derived from the monomer represented by the general formula (1) is from 5 mol % to 40 mol % with respect to 100 mol % of structural units derived from all monomers; a content of the structural unit derived from the monomer containing a carboxylic acid (salt) group is from 60 mol % to 95 mol % with respect to 100 mol % of the structural units derived from all the monomers; 2 mol % or more of the carboxylic acid (salt) groups in the polymer are neutralized with a volatile base and/or a nonvolatile base; 0 mol % to 35 mol % of the carboxylic acid (salt) groups in the polymer are neutralized with the nonvolatile base; and 0 mol % to 100 mol % of the carboxylic acid (salt) groups in the polymer are neutralized with the volatile base.

The present invention relates to sizing compositions, glass fibers at least partially coated with sizing compositions, and glass fiber reinforced composite materials. In one embodiment, a sizing composition comprises at least one maleic anhydride copolymer, at least one coupling agent, and a reaction product of an alkoxylated amine and a polycarboxylic acid, which is further reacted with an epoxy compound.
