METALGUARD® A65P
Heavy-Duty Extended Service Coolant Inhibitor Package Supplemented with Phosphate
25+ years in coolant additivesDecades of chemical expertise Global manufacturing and distribution
METALGUARD A65P is a fully-formulated, extended service additive package that offers outstanding aluminum corrosion control in addition to protection for copper, brass, solder, steel and cast iron. A65P’s substantial nitrite content will also control pitting/cavitation damage to diesel engine wet sleeve cylinder liners.
When blended with ASTM antifreeze grade ethylene glycol/water in accordance with WEBA’s blending instructions, METALGUARD A65P will produce an antifreeze concentrate which contains a minimum of 2400 ppm nitrite. It is borate and 2-ethylhexanoic acid free but contains a low concentration of silicate to meet ASTM D4985.
METALGUARD A65P contains the same ingredients and has the same properties as WEBA’s METALGUARD A65, except that phosphates are used instead of borates in the pH buffering and corrosion inhibition system. In the European Union (EU) sodium borates have been re-classified as reproductive toxins, Category 1b. This re-classification imposes new safety and operational requirements that make it impractical to use borates in coolant in the EU. In the USA, sodium borates have remained classified as a Category 2 reproductive toxin and will continue to be used as a coolant ingredient.
