Most of the wood adhesives currently on the market are formaldehyde-based adhesives (UF, MUF, PF) which account for more than 80% of the total volume, unavoidably releasing formaldehyde – a carcinogenic compound. Unfortunately, there is no ideal replacement for them at the moment. The formaldehyde-free wood adhesives presently available on the market are polyisocyanates and soybean protein-based adhesives, but they are either very costly, strict operation procedure, or suffer from poor water/moisture resistance, very hard to occupy market.
Therefore, cost-competitive high-performance formaldehyde-free adhesives, in particular formaldehyde-free adhesives derived from renewable resources, will have great promise in wood panel industry.
WMB’s patent-pending Biobased formaldehyde-free wood adhesives are derived from forestry/agricultural biomass/residues. The adhesives are not only formaldehyde-free, with superb water/moisture resistance, but also are of a lower cost if compared with polyisocyanates and soybean protein-based adhesives or PF adhesive. The adhesives prove to be applicable in manufacture of a variety of wood panels:
WMB biobased wood adhesive would transform the wood products into greener products with zero formaldehyde emission.
