Latest Patents

Steiner holds a patent for a phenol formaldehyde adhesive designed for bonding wood pieces with high moisture content. This improved resin does not require fillers or extenders and is capable of bonding wafers or veneers that have a moisture content of 10% or above. The adhesive composition is created by mixing a caustic solution of a high molecular weight PF resin with a dispersion of PF resin that can swell in aqueous caustic medium without dissolving. Additionally, alkylene carbonates or phenol resorcinol formaldehyde resins are included, and borax may be utilized as an option. The process involves converting a solution of PF resin into a fine particle size through methods such as precipitation, spray drying, or freeze drying, while partially cross-linking the resin during or after the formation of the dispersion.
