A formaldehyde binder is described for use in lignocellulosic sheet materials such as particleboard, plywood or blockboard, in which a formaldehyde-based adhesive is used. The binder comprises a solution of (a) at least one organic hydroxy compound. with the exception of C1-4 monohydric aliphatic alcohols, and (b) at least one amide, in water, and optionally (c) an organic compound which acts as a solvent for (a) and (b) and also reacts with formaldehyde. e.g. a C1-4-aliphatic monohydric alcohol, and optionally (d) a water-soluble inorganic compound, e.g. an alkali metal or alkaline earth metal halide. |
