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. Composite boards, such as wood-based panels, can be produced using this adhesive resin. The production of the aminoplastic adhesive resin includes the reaction of urea with 5-hydroxymethylfurfural (5-HMF) and glyoxal. The adhesive resin can be used in the production of wood-based panels such as particleboards, fiberboards and products usually called, among others, plywood and/or blockboards.

A curable adhesive that is modified to allow spray application and polymerization seamlessly during the process of epoxy resin vacuum infusion.

An encapsulated perfume composition comprising at least one perfume-containing aminoplast core-shell microcapsule dispersed in an aqueous suspending medium, the microcapsule being characterized in that it bears a positive charge.

One aspect of the present invention is a thermosetting release coating agent composition including an alkyl etherified melamine resin (A) and an acid catalyst (B), in which an alkyl ether group in the alkyl etherified melamine resin (A) contains an ethyl ether group, and the alkyl etherified melamine resin (A) has a weight-average molecular weight of 500 to 1,100.
