Product introduction：
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.
Product Features:
l Convenient，by adding water for dissolution
l Quick solidification and high agglutination intensity
l Ideal cold solidify and hot solidify
l Excellent resistance to heat and weathering
l Long storage life, easy to use and transportation
