Petcor 3600

Barium Free Corrosion Inhibitor

Description

Petcor 3600 is a non-emulsifiable, alkali resistant, water displacing rust preventative which is particularly effective removing water from metal parts after machining operations or alkali cleaning.

Petcor 3600 can be blended with a wide range of base stocks or petroleum solvents depending on the type of film required.

The most effective protective film is obtained from solvent cutbacks of 3600 once the solvent has evaporated. Oil blends will produce softer coatings which are less effective. The water displacement and non-emulsifying properties (even in the presence of alkali) are not affected by the use of oil or solvent.

Petcor 3600 contains no Barium.

Advantages

• Excellent non-staining rust preventive.
• Free from heavy metals, such as Barium; improves environmental profiles and helps reduce disposal cost.
• Demulsibility at all additive concentrations.
• High stability in the presence of alkali.
• Excellent solubility in a wide range of base stocks and solvents.

Application

• Use as a rust and corrosion inhibitor. Protection is obtained from solutions containing as little as 5% Petcor 3600.
• Concentrations of 5% to 15% of Petcor 3600 in mineral spirits will provide humidity cabinet protection for 30 to 90 days or more.
• When used in low concentrations, the water displacing characteristics will be improved by adding 1% to 3% of a suitable dewatering agent.

Solubility

Petcor 3600 is soluble in most common solvents and petroleum and synthetic lubricant base stocks. Insoluble in water. However, it is recommended to verify the solubility in the base stocks used and compatibility with other additives.
