Melamine Resin

What is melamine?

Melamine resin was discovered by W.F.Talbot. He applied to patent it on 1936. melamine formaldehyde is a hard, thermosetting plastic material. This product that most of all is named MF made from melamine + formaldehyde by polymerization.

MF resins are fully seems like urea-formaldehyde (UF) and are fully compatible with them. So co-reacted with them to reduce formaldehyde emissions from particleboard. Furthermore to prevent degradation of glue bonds caused by hydrolytic degradation of the UF polymers. Resin blend calls melamine–urea–formaldehyde (MUF). Compared to natural woods and wood veneers. It`s composite boards and overlay materials have improved heat, moisture, scratch, and chemicals resistance.

Butylated form, dissolved in n-butanol and xylene. It is used to cross-link with alkyd, epoxy, acrylic, and polyester resins. There are many types, varying from very slow to very fast curing.

What is Formaldehyde?

Formaldehyde (systematic name methanal), is a naturally occurring organic compound with the formula CH2O (H-CHO). It also is the simplest of the aldehydes (R-CHO). The common name of this substance comes from its similarity and relation to formic acid.

Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the instal for production of formaldehyde was estimated to be 8.7 million tons.It is mainly used in the production of industrial resins, e.g., for particle board and coatings.

What is Melamine Formaldehyde Resins?

Non-methylated melamine formaldehyde resins are hard, very durable and versatile thermosets with good fire and heat resistance. In addition for market, along with resins and additives, we offer extensive formulating expertise. Our resins are adaptable to a wide variety of system parameters and, when cured, are colorless, long-lasting, and solvent resistant.

Typical applications include:

  • Laminate flooring and counter-tops
  • Cabinetry
  • Composites
  • Surface coatings
  • Modifiers in materials such as textiles, tires, paper, fertilizers, glass and metals
  • Also  in textile finishes
Melamine resin uses:
  • Industrial uses such as  kitchenware, laminates, overlay materials, particleboard, and floor tiles.
  • Flame-resistant materials.
  • Textiles such as upholstery, firemen uniforms, thermal liners, and heat resistant gloves and aprons.
  • Also used as fire-retardant additives in paints, plastics, and paper.
  • It uses specially in the fabrication of particleboard. It`s often blended with UF. That improves the scratch and flame resistance also acts as flame retardant.
  • Saturating decorative paper, laminated under heat and pressure, fusing the laminate onto particleboard.
Melamine-based resins as wood adhesives:
Melamine Resin Laminating Grade
Melamine powder uses in coating woods

MF, MUF, MUPF, PM(U)F used as wood adhesives. Almost one of the largest groups of amino-plastic resins. this is under reaction of formaldehyde with melamine using urea, phenol, and components. The hardened resins show duroplastic hardening behavior.

This product show higher hydrolysis resistance compared to UF resins. The field of application comprises the production of wood-based panels such as particleboards, MDF, OSB, plywood, blockboards, and especially for use under humid conditions. The molar ratio between formaldehyde/reactive amino groups distinctly determines reactivity. The degree of cross-linking, and hence the bonding strength. Co condensation between melamine, formaldehyde, and other components is possible, furnishing co condensates with improved properties and reduced price.
