GOST 14231-88

The resin is a polycondensation product of urea and formaldehyde.

The resin is made according to modern technology, using as raw material of urea-formaldehyde concentrate that provides a stable quality of resin and consumers eliminates ejection of methanol into the air that is present in the resins produced from formaldehyde.

Appearance: Homogenous suspension from white to light yellow color without foreign inclusions.

Application:

It is used as a binder in the production of plywood, glass fiber, for bonding pieces of furniture, millwork and building products, to strengthen the soil in road construction and drilling (binder).
