"Pre-inhibited glycol is a specially formulated chemical additive for protecting system metals from corrosion. It is a multi-metal corrosion inhibitor and prevents corrosion in multi-ways.
It modifies the metal surface by absorption and making it less susceptible to corrosion. It also gives a high degree of corrosion protection to engine components radiators, water pump seals, and heat exchangers. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations.
