Melamine-Formaldehyde (MF) resins
MF resins are aqueous solutions of rather low molecular condensation products of formaldehyde and melamine, in many cases modified with certain additives.
These resins are characterized by 55-60% solid content, a low viscosity (15-27 DIN 4 sec.) and a colorless and clear appearance.
MF resins are applied for paper impregnation; thereby resin penetrates into the paper and through a combined thermal pressing and curing process a composite of paper and polymer with excellent surface properties can be produced.
Decorative and overlay papers (also fortified), filled with melamine resin, are used for lamination on particle boards or similar for the furniture and flooring market as well for decorative laminated boards, used in applications with heavy demands on chemical and mechanical resistance and hygienic properties of surfaces, e.g. kitchen, lab, hospitals, etc.
To improve the large number of surface properties (flexibility, transparency, etc.) and to improve the impregnation and the lamination process, modifications of the melamine resins with different types of additives is very important.
Urea-Formaldehyde (UF) resins and adhesives
UF resins and adhesives are classified as thermosetting polymers and are produced by a condensation polymerization reaction between urea and formaldehyde. These UF polymers have proven to be very good adhesives for wooden materials. Due to their high reactivity and cost efficiency, they are the most popular binders for interior products.
Arta has manufacture of UF resins and adhesives designed for a wide variety of end uses, such as wood-based panels, furniture.
Arta deliver UF resins and adhesives both in liquid form with a wide range in viscosity, solids content, and molar ratio.
Arta tailor makes resins and hardeners, for each customer. This customizing involves designing the resin so the viscosity, solids content, reactivity, tack, and emission properties meet the specified process and environmental needs.
