BONDERITE® M-ZN 2748 R3

Features and Benefits

Nitrite- and nickel-free bicationic phosphating process for steel, galvanized steel and alloy coated (Zn/Ni) steel.
BONDERITE® M-ZN 2748 R3 (GRANODINE 2748 E-3) is a pink, clear, nitrite- and nickel-free bicationic phosphating process for steel, galvanized steel and alloy coated (Zn/Ni) steel. It generates a fine crystalline coating of manganese containing zinc phosphate with good corrosion protection. It is an excellent foundation for subsequent painting/organic coating and has a low tendency for encrustation. Please note: BONDERITE M products are used in the surface modification of metals and usually applied in a multi-stage process. The performance of these surface treatments depends on various factors such as the preceding cleaning or etching steps (BONDERITE C portfolio), line design or process parameters.
  • Nitrite- and nickel-free
  • Very good corrosion protection properties
