Infusible and insoluble melamine-formaldehyde condensation products having a mean particle size <1m are prepared by reacting an aqueous solution of melamine and formaldehyde or an aqueous solution of a melamine-formaldehyde precondensate, in the presence of a protective colloid in the pH range 6 to 8 until a solid phase is formed. Reaction is preferably carried out at elevated temperature, e.g. at the boiling point of the solution. 1.5 to 6 mols. of HCHO may be used per mol. of melamine. Other aminoplast forming compounds (e.g. urea and its derivatives and other amino-triazines) may also be present. Examples of protective colloids are starch, tragacanth, gelatine, agar,-agar, polyvinyl alcohol, the sodium salt of carboxmethylcellulose and a hydrolysed polymer of maleic anhydride and styrene. The amount of protective colloid used may be 0.1 to 10% by wt. based on the total amount of aqueous reaction mixture. The starting solution may contain from 5 to 25% by wt. of resin-forming constituents. The precipitation reaction may be carried out at the boiling point of the reaction mixture. | ||||||

An improved oxazolidine-based hardener to be used with a resorcinol resin or a tannin resin as the adhesive for the bonding of wood articles. Preferably, an oxazolidine is combined with a base such as NaOH and a powdered absorbent such as wheat flour. The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength requirements after the glue is cured at room temperature for under 24 hours. The improved hardener composition is storage stable; it can be prepared anytime before its use, thus eliminating the need to prepare a hardener immediately prior to the glue use. Since it is formaldehyde-free, it eliminates the safety issues associated with handling formaldehyde or paraformaldehyde. Also, the hardener provides flexible gel time or working time. Since the resins can be cured at room temperature, heating in an oven is not needed but could be used to reduce curing time. If radio frequencies are used to cure the resins, the exposure time can be reduced. | ||||||

This invention relates to benzylic ether phenolic resole resins prepared in a sealed reaction vessel and their uses. The benzylic ether phenolic resole resins are prepared by heating phenol and an aldehyde in a sealed reaction vessel in the presence of a divalent metal catalyst without removing water generated by the reaction until an appropriate endpoint for the resin is reached. The benzylic ether phenolic resole resins produced by the process are preferably free or essentially free of unreacted formaldehyde and can be used in the resin component of phenolic-urethane foundry binders to make foundry cores and/or molds by the cold-box and no-bake processes. The cores and/or molds are used for making metal castings. | ||||||
