TH551 Metal Passivator (Benzotriazole derivative)
1. Description
It has good anti-oxidation and copper corrosion inhibition. It is able to form the inactive film or create the chelate complex in combination with metallic ions to prevent metal oxidation.
2. Applications
It is used primarily for turbine oils, oil film bearing oils, industrial gear oils, transformer oils and circulation oils. It is forbidden to mix with ZDDP, otherwise the settling would occur.
3. The recommended dosage
From 0.03% to 0.1%.
