A newer harder known as solvent-free epoxy hardener is able to cure epoxy without the addition of organic solvents. This hardener is more useful from an environmental and regulatory standpoint because it does not permit evaporation of volatile organic compounds (VOCs). Solvent-free epoxy hardener yields epoxies with good adhesion and powerful mechanical strength; as well as improved chemical resistance and mechanically durability in odor sensitive regions. Such areas include some indoor food prep areas which tend to be more sensitive to their environments.
