For flooring, different types of solvent-based contact adhesives, dispersions and even PSAs are applied.
Parquet is mainly bonded with three different types of adhesive, namely solvent — based synthetic resin adhesives, reactive resin adhesives and dispersion adhesives.
In spite of ongoing efforts to reduce the emission of volatile organic compounds (VOCs), solvent-containing synthetic resin adhesives still dominate the global market in flooring because they are inexpensive and have good application properties. They comprise a mixture of solvents (methyl acetate, acetone, ethanol, methyl alcohol), dissolved synthetic resin (polyvinyl acetate), and mineral fillers (e. g. chalk). The overall VOC content typically ranges between 20 and 25%.
Solvent-containing synthetic resin parquet adhesives do not contain water, in order to avoid any swelling of the parquet woods. Parquet-floor layers also benefit from this type of adhesive as they are easy to use. The most environmentally friendly way to bond parquet floors is to use waterborne dispersion adhesives, consisting of polyvinyl acetate plastics dispersion as binder, and chalk as the mineral filler.
Another example of surface bonding adhesives in building is that of wallpaper adhesives. These water-based adhesives have as their main components methylcel — lulose and thickening agents such as lignocellulose, modified starch and mineral fillers [15].
