Abstract
A water repellent coating for wood substrates is presented. The coating comprises a highly dispersed mixture of polytetrafluoroethylene, alkyd resin and microcrystalline wax. Dispersion of the polytetrafluoroethylene and microcrystalline wax as discrete particles prevents delamination of successive coats while providing intercoat adhesion. Also presented is a process for the preparation of water repellent wood coatings that prohibits microcrystalline wax breakdown.
