Red BPO (Benzoyl Peroxide) Hardener Paste For All Car Body Fillers

short description:

European Quality, Environmentally friendly,Delicate paste without layering and fading, with one-year warranty!

50% BPO Hardener Paste(Polyester Putty Hardener Paste) is widely used to cure epoxy resins. However, simply adding a hardener to an epoxy resin may not cause the epoxy mixture to cure quickly enough. If this is the case a different hardener may be required. Also, hardeners with certain additives can be used. These hardener additives serve as catalysts that speed up the curing process. Hardeners are almost always necessary to make an epoxy resin useful for its intended purpose. Without a hardener, epoxies do not achieve anywhere near the impressive mechanical and chemical properties that they would with the hardener. The correct type of hardener must be selected to ensure the epoxy mixture will meet the requirements of the application.
