Urea melamine formaldehyde adhesive has the combined properties of urea formaldehyde and melamine formaldehyde resins with optimal performance. The high resistance of this product to moisture significantly reduces the amount of water absorption in compacted boards. In addition, the low free formaldehyde content of this adhesive places it in the standard category of E 1 adhesive in the European Union. In places where the production process is intermittent and requires the accumulation of glue for a long time, urea melamine formaldehyde powder powder is used instead of liquid glue.
