PROCESS FOR THE MANUFACTURE OF THERMALLY CURABLE RESINS AS WELL AS RESINS OBTAINABLE BY THE PROCESS

Processes for the manufacture of thermally curable resins contain the step of the reaction of a polycondensation-capable phenolic compound and/or of an aminoplastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to formation of polycondensation products. The HMF includes at least one HMF oligomer. Further, thermally curable resins produced by such processes may be used for the manufacture of a wood composite material.

High flow urea-formaldehyde powders for particleboard and fiberboard manufacture

Particulate binder compositions made with amine-aldehyde resins and methods for making same are provided. The method for making the particulate binder composition can include spray-drying an amine-aldehyde resin having a total aldehyde compound to total amine compound molar ratio of about 1.55:1 to about 1.65:1 to produce a particulate binder composition. The particulate binder composition can have a fusion diameter of about 35 mm to about 70 mm.

MODIFIED AMINOPLASTIC ADHESIVE RESIN, PROCEDURE OF ITS PREPARATION, AND COMPOSITE MATERIALS PREPARED USING THE MODIFIED AMINOPLASTIC ADHESIVE RESIN

A temperature-curable aminoplastic adhesive resin that is a (poly)-condensate of: (i) at least one aminoplast-forming chemical; (ii) 5-hydroxymethylfurfural (5-HMF), its oligomers and/or its isomers; and, (iii) at the least one second (poly-)condensable chemical produced in the presence of an organic sulfonic acid. Composite boards, such as wood-based panels, can be produced using this adhesive resin. The production of the aminoplastic adhesive resins includes the reaction of urea with 5-hydroxymethylfurfural (5-HMF) and glyoxal in the presence of an organic sulfonic acid as a hardener. The adhesive resin can be used in the production of wood-based panels, such as, particleboards, chipboards, fiberboards and products usually called, among others, plywood and/or blockboards, in the presence of an organic sulfonic during curing.
