Temporary Inhibitors

Temporary Rust Inhibitors for Steel

• E-Tec 527 is a mild water based composition formulated to provide rust protection for steel surfaces when stored indoors. It leaves a dry, invisible film which will not affect subsequent operations. Excellent for protecting steel surfaces while in process of manufacture. It does provide some mild cleaning action and can be used in tumbling or burnishing operations to prevent rapid oxidation of steel surfaces.
• E-Tec 527B same as E-Tec 527 but also provides temporary corrosion protection for brass and aluminum surfaces.
• E-Tec 527C contains borate and is formulated to provide rust protection for steel surfaces indoors. It does not contain nitrite, phosphate or diethanolamine.
• E-Tec 527C is used at 1-2% by volume in water, and at 100-180° F. At 2% by volume E-Tec 527C will pass the ASTM-D04627-86 cast iron chip test.

Copper and Brass Conditioner/Corrosion Inhibitor

• E-Tec 529 is a liquid concentrate which is diluted with water and used to produce chemically bonded mono-molecular barrier film on copper, brass and bronze surfaces. It provides temporary protection against corrosive attack by Hydrogen Sulfide, Sulfur Dioxide, Carbon Dioxide, salt solutions and moisture. It inhibits corrosive attack for weeks to months for protection of parts while in process or short term storage.

Rinse Water Additive

• E-Tec 528 is a mild liquid based chemical composition formulated to help in the elimination of staining, streaking, water spotting and tarnishing of plated metal surfaces following water rinsing.
