Water uptake, moisture absorption and wettability of beech veneer treated with N-methylol melamine compounds and alkyl ketene dimer

With Beech veneers being treated with 10% solid content of the chemicals from paper (Alkyl ketene dimer, AKD), wood (N-methylol melamine, NMM-1) and textile industry (fatty acid modified N-methylol melamine, mNMM-2), the results showed that the treatments with these chemicals considerably increased the water repellence effectiveness (WRE) of veneers in the initial submersion phases. In this paper, veneers treated with Nmethylol melamine and AKD chemicals were investigated on water/moisture related properties and their stability after cyclic tests.
