Polypropylene has a number of very useful characteristics including excellent chemical resistance and the fact that almost nothing will stick to it. However, this does mean that most joints involving polypropylene are mechanical in nature. This is the same with polypropylene sinks, which cannot be glued or bonded to any bench top using standard sealants or adhesives. For this reason the sinks are usually supplied with a gasket and, when under mounting sinks, we recommend the use of either an aluminium strengthening strip under the sink flange, or multiple screws directly through the flange. Any additional silicon used as a sealant may stick to the bench but will not stick to the polypropylene.
