Product Description:
Urea-Formaldehyde Powder Resin is a dewatered white powder made up of urea and formaldehyde, with the same chemical and physical properties as those of liquid resin. It is the adhesive with high water-resistant, mould resistant, and pollution-free. The combination intensity of the timber is greater than temperature. It is an ideal adhesive for artificial boards and all other wooden products, as it is water-soluble because of its low-molecular condensation polymer, good in fluidity and simple process.
