Anti-tarnish Agent No.220 is a clear, odorless, copolymerized acrylic, water based lacquer used over metal parts to yield a corrosion and scuff resistant finish. Since the material is water based, containing no solvents, it is non-flammable and produces no polluting fumes. Fire hazards are eliminated. The final finish is stable to light and heat and resists weathering and corrosion atmosphere.
