APPLYING RELEASE AGENT: This product is adhesive and will bond to many surfaces. For epoxy to epoxy applications where adhesion is not desired, an application of paste wax followed by Ease Release® 2125 PVA. For other surfaces such as metal or plastic, a silicone based spray release such as Universal Mold Release may be used to prevent adhesion.
Removing Epoxy Uncured / Non-curing epoxy: Scrape as much material as possible from the surface using a scraper. Clean the residue with E-POX-EE KLEENER®, lacquer thinner, acetone or alcohol. Follow safety warnings pertaining to solvents and provide adequate ventilation.
