Urea Melamine Formaldehyde (UMF) combines the properties from urea formaldehyde and melamine formaldehyde polymers with optimum performance. High resistance to water minimizes water absorption in compact boards. Also, because of low formaldehyde emission it is compatible with E1 European standard.
Applications
- Manufacturing of moisture resistant wood particle board, plywood and other wood products.
- For preparation and bonding of both low and high pressure paper laminates and overlays.
Storage life
1 month at 25 ºC
Packaging
20 liter HDPE plastic drums and 20 – 22 MT stainless steel tanks
