Not much is known about Affix other than it is a sponsor on some racing liveries for vehicles, such as the Itali GTO. Its name does suggest that it is a brand or company that makes and sells adhesives for floor tiling. Its name "Affix" also means to "stick or attach something to something else", which is fitting for an adhesive manufacturer.
The company could possibly be based on Norcros Adhesives.
