Urea-Formaldehyde (UF) resins and adhesives
UF resins and adhesives are classified as thermosetting polymers and are produced by a condensation polymerisation 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. Dynea has world-wide manufacture of UF resins and adhesives designed for a wide variety of end uses, such as wood-based panels, furniture, load-bearing constructions and wooden building products.
Dynea deliver UF resins and adhesives both in liquid and powder form with a wide range in viscosity, solids content, and molar ratio. One shot adhesives, powder adhesives with incorporated hardener, can be delivered ready-to-use. A wide range of resin technologies have also been developed, including a broad spectrum of hardeners, to offer the best possible solution for the different process conditions employed by a variety of customers.
Dynea tailor-make products, both resin and hardener, for each customer. This customising involves designing the resin so the viscosity, solids content, reactivity, tack, and emission properties meet the specified process and environmental needs. Our UF products are environmentally friendly and capable of meeting or exceeding the various performance criteria required by the different standards ANSI, NPA, ASTM, EN, and ISO.
