It’s a minor ingredient. Teflon has been used as a MINOR ingredient in a lot of stuff including most all commercial floor wax. The key is a minor ingredient. It’s bonding properties are still only as good as the base wax product. According to DuPont, the addition of the powder may enhance the protective properties but it still remains the minor protective agent.
The key is to read what DuPont says about the products and the recommended applications. The spray is a “between wax” product, there are many of these brands around. The DuPont branded waxes with Teflon added powder, again, as the minor agent, call for reapplication in a time frame similar to all other products on the market. Why, because they are only enhanced with Teflon powder as an aide and rely on quality wax for bonding. Why again, because Teflon will not bond, thus the reason for the additive powder as a minor agent to enhance the wax properties.
