| Résumé : |
Adhesives have a high degree of human exposure both at the industrial and consumer level. During the production of corrugated boxes the operator will be exposed to solvents volatilising as will the connsumer applying a construction adhesive such as wood glue for DIY purposes at home. So lowering the VOC is a major aim for adhesive producers and where possible the solvent containing formulations are being replaced by water based ingredients.
A major raw material ingredient in an adhesive formulation is the polymer dispersion. The most common types of polymer dispersion are based on either styrene butadiene (SBR) or acrylic chemistry and supplied as an aqueous system. In addition, the suppliers of polymer dispersions have continued to lower the VOC by reducing the levels of free monomer in their products because monomers are also volatile and harrmful to humans as well as the environment. Consequently, the VOC reduction in polymer dispersions has removed those ingredients previously responsible for microbiological protection of the raw material and today yielding products susceptible to microbes, which can proliferate in the final water-based adhesive. |
