Urea Melamine Formaldehyde (UMF) combines the properties from urea formaldehyde and melamine formaldehyde polymers with optimum performance. This melamine modified urea formaldehyde adhesive has very high bending strength and is suitable for production of high flexural strength wood products. After mixing with water, it is used as liquid adhesive and the level of melamine is adjusted to improve the bonding strength.

Applications

  • Production of high flexural strength plywood, wood particle board and medium density fiberboard (MDF).

Storage life

6 months at 25 °C

Packaging

Laminated 25 kg PP bag
