Using ACF-50 which is a Anti-Corrosion Formula, help to keep these parts clean after being Vapour Blasted.
It is an ultra Thin Fluid Film Compound (TFFC) that actively treats metal using advanced polar bonding technology. ACF-50’s synthetic inhibitors and active chemistry penetrates through oxide deposits (white powder) to the base of the corrosion cell where it emulsifies, encapsulates and then lifts moisture (the electrolyte of a corrosion cell) away from the metal surface. ACF-50 then allows the moisture to evaporate while providing an atmospheric barrier that prevents further moisture contact. With the electrolyte removed the corrosion process is halted. ACF-50 actively penetrates and creeps into the tightest seams, joints micro cracks and around screw heads, displacing moisture and other corrosive fluids in these corrosion prone areas. ACF-50’s thin film acts like an off-switch for corrosion.
