MELAMINE RESIN

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. In its butylated form, it is dissolved in n-butanol and xylene.

It is an amino resin and has various material advantages, such as transparency, better hardness, thermal stability, excellent boil resistance, scratch resistance, abrasion resistance, flame retardant, moisture resistance and surface smoothness, which lead MF to large industrial applications. They are generally used for products where the color or pattern of the substrate is retained with a transparent melamine protective coating or binder.

Cement additives/ Adhesion improvement

A cement slurry additive consisting of methyl cellulose, melamine-formaldehyde resin, and trioxane has been proposed for better bonding of cement to the casing string. Bisphenol-A  epoxide  resins, with amine based curing agents, sand filler, and a mixture of n-butanol and dimethyl benzene as a diluent, have been proposed as additives to increase the adhesion properties of cement. Quaternary ammonium salts (C₁₀ to C₁₈ alkyl benzyl dimethyl ammonium chloride) added in 40 ppm and 2% of sodium chloride effect an increase in the strength of the cement rock and the adhesion properties by 50-80%.
