Corrosion Preventives2018-03-29T11:43:00+00:00


Used in the steel and metalworking industries. Formulated to be readily removed through conventional alkaline metal cleaning or degreasing procedures. Specifically developed to protect metal surfaces from corrosion for up to one year; can be applied using spray, dip, brush or electrostatic techniques.

Metal Rust Preventives

Interim, in-process and final rust inhibitors designed to protect metal parts during the manufacturing process and for medium to long-term indoor storage of metal surfaces, both ferrous and non-ferrous. Proper selection and application of the fluid can result in substantial cost benefits. Used in such processes spray washing and slushing equipment to remove residual coolant fluid and grinding/honing debris from assembled bearings and components, steel and cast iron alloys and uncoated and coated steel strip.

Edge Sealers

Edge sealers are formulated to be applied to the outer-lap of the coil and to the sidewalls. Edge sealers typically utilize volatile components and waxes to provide barrier protection to the coil. Subsequently, this barrier film offers protection from a variety of environmental contaminants, including acid atmosphere. These types of products are generally considered very robust rust preventives but often are more difficult to remove when compared to common mill oils. Today, Quaker offers environmentally friendly (low VOC) edge sealer technology.

Mill Applied Lubricants (Prelubes)

A rust inhibitor that also provides enhanced lubrication properties as compared to mill oils. Generally, prelubes will offer better rust protection from humidity as compared to most mill oils and will clean easily too. These types of products contain additives that offer increased hydrodynamic and boundary lubrication. In some cases, these products also contain extreme pressure additives for lubrication.

Slushing Oils (Mill Oils)

These products embody the overall value expected from a slushing oil, including: excellent humidity protection, stain resistance and removal from the surface. The aforementioned characteristics of a slushing oil are typically the formulating characteristics of all mill oils currently available. However, varying degrees of humidity protection are available in mill oils and are commonly referred to as “enhanced” mill oils. These products offer the same performance characteristics of standard slushing oils, but exceed the overall humidity protection.

Vanishing Oils

Vanishing oils are also formulated with volatile components, but contrary to edge sealers, they are formulated to leave a very low residual film on the surface. As a result, vanishing oils do not offer the same level of humidity protection or lubrication characteristics as compared to edge sealers, prelubes or slushing oils. However, the very low residual film does allow for wet tempering and short to medium term protection while having very little impact on downstream processes. These oils offer light duty stamping lubrication.



Hot melt dry film technology, free of solvent or water carriers. Provides excellent corrosion and industrial lubrication properties for ferrous and non-ferrous metals. Applied electrostatically or by other conventional methods for use as a corrosion preventive, rust inhibitor or mill applied lubricant. Electrostatic application allows for in-house, in-line application.

QUAKER DRYCOTE® is a corrosion preventive dry film for stainless steel and high strength steel applications. It can offer transport protection and long-term indoor storage solutions. Efficient applications require electrostatic methods, which will need heated delivery and application oiler cabinet.
