Melamine-formaldehyde resins

Application: Melamine-formaldehyde resins are used in the process of manufacturing FB, waterproof plywood, МDF, OSB, LVL. Melamine-formaldehyde resins is a product of polycondensation of melamine in formaldehyde solution. Melamine contains in its molecule 3 amino groups  capable to react with formaldehyde. Hydroxymethylation by substitution of one atom in amino group goes quickly. Formation of mono-, di- and trimethyl derivates runs in alkaline condition. Further condensation is conducted by temperature 80-90°С and рН 7,5:9. Hydroxymethyl groups interact forming dimethylenether bonds -СН2-О-СН2– or methylen bonds -СН2-. Resin quality enhancement is reached by adding modifiers to the batch mixture. Melamine resin manufacturing shops “Safe technologies Inc” provides “know how” in the field of melamine-formaldehyde and melamine-urea-formaldehyde resin synthesis for FB, waterproof plywood, МDF, OSB, LVL from methanol free formaldehyde solution. Methanol free concentrated formaldehyde solution process allows conducting synthesis of melamine-formaldehyde as well as phenol-formaldehyde resins on the same equipment in a single shop, for the fullest range of wood based panel fabrication. We organize manufacturing of the following kinds of resin: Melamine-urea-formaldehyde resin for MDF boards, emission class Е-1 и Е-0 Melamine-formaldehyde for laminating MDF and chipboards Since this “know how” is unique in Russia, detailed information is available on request only.
