Abstract: A phenol-formaldehyde resole resin is combined with an ammonia-based formaldehyde scavenger to produce a product useful, for example, as a binder used in the production of glass fiber insulation products. The starting resin may have a free formaldehyde content of 1.5 to 14 wt. %, based on a total weight of the resin, and the resin and scavenger may be combined at a molar ratio in the range of 0.1 to 5. The resulting binder may have a free formaldehyde content of 1 wt. % or less, based on a total weight of the reaction product. This binder may then be applied to a glass fiber base material in a conventional manner.

Abstract: A method of making core board product may be under the control of a processing unit. A first tubular core may be dispensed to a conveying portion to support the first tubular core at an interim location. The first tubular core may be conveyed to a flattening position under pressure of a compression member. The first tubular core is substantially compressed between the compression member and a flattening surface. The steps of dispensing, conveying, compressing may be repeated for at least a second tubular core. The second tubular is substantially compressing core against the first tubular core. The substantially compressed first tubular core and second tubular core may be fastened together in an abutting relationship with a plurality of fastening members so as to form the core board product.

Abstract: Alkenyl succinic anhydride (ASA) size emulsions are prepared using a grafted cationic acrylamide starch co-polymer as an emulsification agent. The ASA size emulsions of the present invention exhibit significantly greater stability compared to presently available ASA size emulsions. The grafted starch co-polymer also is a more efficient emulsification agent for ASA size, permitting the use of less emulsification agent, thereby saving cost.

Abstract: Carbon disulfide and hydrogen are reacted in the presence of a catalyst to form methyl mercaptans. The catalyst may be V2O5, Re2O7, or MnO supported on a substrate of CeO2, ZrO2, TiO2, Nb2O5, Al2O3, SiO2, Ta2O5, SnO2, or mixtures thereof High conversions of carbon disulfide and high selectivities to methanethiol are obtained by the present invention.

Abstract: A binder composition based on phenol-formaldehyde resin for making fiberglass insulation and related fiberglass products (glass fiber products) and containing a copper or vanadium odor-eliminating agent, such as cupric chloride, that when cured exhibits a lower amount of odor caused by the presence of trimethylamine.

Abstract: A composition of matter for surface sizing of paper and other cellulosic products. In particular, the composition is a styrene/acrylic acid ester copolymer latex made by emulsion copolymerization without surfactants.

Abstract: A method of forming a composite panel includes the steps of supplying a material to a forming station, supplying a dry additive to the material at the forming station, producing a mat comprising the material and the additive, and applying heat and pressure to the mat to produce a composite panel. An apparatus for forming a composite panel includes a reservoir of raw material and at least one forming station configured to form a mat of the raw material. A dry material dispensing assembly introduces an additive to the forming station, and press applies heat and pressure to transform the mat into a panel.

Abstract: A substantially infinitely water-dilutable resole (P:F) resin solution useful for preparing an aqueous binder composition and the related method of its use for making glass fiber products, especially fiberglass insulation.

Abstract: The present invention provides a system and method for determining adhesive resin distribution on wood flakes to be formed into a wood-based composite. Where a predetermined amount of adhesive resin has been sprayed onto a selected amount of wood flakes being tumbled in a blender, the method includes the steps of: removing a sample of sprayed wood flakes at the output of the blender and placing the sprayed wood flakes on a scanning bed; scanning the sprayed wood flakes with a scanner having at least 1200 dpi resolution with 1800 dpi interpolation to provide image data; using image analysis software with resin analysis macros to filter the image data to provide a high contrast image that shows each adhesive resin spot differentiated from the wood flake on which the adhesive resin spot is situated; and measuring and analyzing the high contrast image to provide an output showing at least a percent coverage of the wood flake by the adhesive resin.

Abstract: Phenol formaldehyde resins that have low free formaldehyde when produced, that maintain their low free formaldehyde levels during storage, and that demonstrate low levels of formaldehyde emissions during processing, curing, and thereafter.

Abstract: Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid).
