Plywood Glue adhesive : Melamine–formaldehyde and melamine–urea–formaldehyde adhesives

Melamine–formaldehyde and melamine–urea–formaldehyde adhesives
Melamine–formaldehyde (MF) and melamine–urea–formaldehyde (MUF)
adhesives have increased water resistance compared to UF adhesives and
therefore are commonly used for the manufacture of semi-weather exposed
and some fully weather exposed products. They are also commonly used for
impregnating the paper sheets that make up the backing in plastic laminates.
However, the high cost of melamine limits the use of MF adhesives. MUF
adhesives provide a lower cost alternative, but with lower bond durability.
MUF adhesives are more expensive than UF adhesives but with improved bond
durability.
