Microcrystalline Wax/Pre-Mixture Liquid Sealant Composition, Method of Manufacture and Methods of Use
20190211226 · 2019-07-11 ·

A method and composition are shown for treating a variety of different substrates with a sealant coating composition which provides a long lasting protective barrier on a selected substrate. First a sealant composition is formulated by combining a micro-crystalline wax with an organic solvent pre-mixture blend. Next, the selected substrate is contacted with the sealant composition and the solvent blend is allowed to flash away, leaving behind a substantially solvent free micro-crystalline wax residue barrier. The solvent blend can be a mixture of hexane and xylene but is not limited to these two particular solvents.
