Idealized subunit of a melamine-formaldehyde resin (R - H, alkyl) Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. [1]
In one large-scale application, melamine is combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high-pressure decorative laminates such as Wilsonartdry erase boards.
Melamine resins are "methylated" by adding excess methanol to the manufacturing process. The result is the incorporation of methoxymethyl functional groups into the structure of the melamine formaldehyde (MF) polymer, resulting in excellent stability even at very high solids content.
2012年10月17日 · Melamine formaldehyde (MF) resin was synthesized by the reaction between melamine and formaldehyde under alkaline condition in tetrohydrofuran medium with 1:3 melamine to formaldehyde molar ratio.

melamine, a colourless crystalline substance belonging to the family of heterocyclic organic compounds, which are used principally as a starting material for the manufacture of synthetic resins. Melamine is rich in nitrogen, a property that is similar to protein. Manufacture and applications of melamine.

2022年10月1日 · Melamine resin. Formaldehyde control. Periodate oxidation. Sucrose. Molecular weight. Leather filling. 1. Introduction. Melamine resin (MR) is a sort of resin with melamine rings terminated with multiple hydroxyl groups, and it is generally prepared via the condensation of formaldehyde with melamine (MFR) ( Fink, 2013, Roy Choudhury, 2017 ).
Melamine-formaldehyde resin, any of a class of synthetic resins obtained by chemical combination of melamine (a crystalline solid derived from urea) and formaldehyde (a highly reactive gas obtained from methane). A complex, interlinked polymer that cures to a clear, hard, chemically resistant.
