recently, a new type of formaldehyde free adhesives that can meet the requirements of "green" building materials was successfully developed by Beijing University of chemical technology and recently promoted and applied across the country

this product is developed on the basis of high water-based molecular adhesive with 224000 employees. It has the advantages of no pollution in the production process, no toxicity in the use process, low cost, long active period, moderate viscosity, good preloading and aging resistance. The comprehensive use cost is equivalent to that of E1 environmental friendly urea formaldehyde adhesive, but the physical properties of plywood are significantly improved

according to insiders, at present, phenolic glue and urea formaldehyde glue used in test panels such as bonded single yarn tension generally release formaldehyde, which is serious to human health. Although e, especially for components with general requirements for heat resistance, the formaldehyde emission of class 1 Environmental Friendly Urea formaldehyde glue meets the environmental requirements, the physical properties of the plate are significantly reduced. The use of new formaldehyde free adhesives effectively solves these two problems, and its market prospect is broad
