Borate Classifications Erode Adhesive Options

Andy Extance – Jul 27, 2011

On 18 June 2010 the European Chemical Agency added boric acid and borax to the candidate list of ‘substances of very high concern’ for authorisation. This raises the possibility that borates could be banned altogether in Europe, despite the fact that they play an important role in many adhesives, particularly starch-based formulations. This presents a huge challenge to formulators, although some have already reacted by eliminating borates from their products. Helping with that effort are potential replacements for borax, such as aluminium sulphate.
