Antifreeze/coolants consist of either ethylene glycol (EG) or propylene glycol (PG) to provide freeze protection while also raising the boiling point of water. Additives are included in the formulation to protect against corrosion and scale deposits. Additives come in three types: inorganic salts (found in “green” conventional products), organic acids (OATs) and hybrid organic acids (HOATs). Organic acids (sometimes referred to as poly-organic acids), are the most robust and long-lasting of the three. They provide superior protection against scale deposits while offering excellent compatibility for maximum convenience. AMSOIL Heavy-Duty Antifreeze & Coolant is premixed 50/50 with ethylene glycol and high-purity water. It uses the latest organic-acid technology to provide outstanding protection while guarding against deposits.
Independent tests reveal AMSOIL Heavy- Duty Antifreeze & Coolant greatly surpasses standards for metallic corrosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum, steel, copper, solder, brass and cast iron as well as aluminum water pumps.
AMSOIL Heavy-Duty Antifreeze & Coolant is a poly-organic acid formulation that does not contain inorganic salts (phosphate, nitrate, nitrite, silicate, borate, amine) found in conventional and hybrid organic acid (HOAT) antifreeze/coolants. These materials are responsible for almost all scale deposits in cooling systems, often forming when the antifreeze/coolant is at the wrong pH or mixed with incompatible products. AMSOIL Heavy-Duty Antifreeze & Coolant virtually eliminates scaling problems.
Antifreeze/coolants that use inorganic salts can be incompatible with each other, sometimes leading to additive drop-out in the form of an abrasive or slime. Determining product compatibility is a hassle and can lead to accidental mixing and maintenance issues. AMSOIL Heavy- Duty Antifreeze & Coolant does not contain inorganic salts, enhancing compatibility. It may be mixed with all ethylene and propylene glycol antifreeze and coolant colors, allowing operators to top-off any system regardless of the current antifreeze/coolant being used. However, mixing propylene and ethylene glycol formulations can make it difficult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to flush the cooling system at the next convenient opportunity.
