Water-repellent or dewatering fluids are conventionally applied by immersion to wet parts. They remove residual water from upstream processes (machining operations using a soluble fluid or degreasing with a detergent, etc.). The immersion tank must be adapted with a system for draining accumulated water.

Parts immersed in a water-repellent fluid can come out dry, without residue, or, depending on requirements, with a protective film against corrosion. This protective film may be imperceptible, waxy, oily, or even greasy.

All products in the MT Protect range contain active substances that work to separate water from the parts by depositing a protective film. 

These corrosion protection products have low surface tension, allowing them to act on parts with complex geometries by reaching the most difficult areas (blind holes, hollow bodies) to deposit the protective film evenly. They can be applied with a paintbrush, brush, by immersion, or by spraying.

Different levels of protection and finish (thin film, thick film, waxy film) are possible depending on the active ingredient content. They can be easily removed using a solvent or alkaline detergent. The MT Protect range meets performance, durability, and operator health and safety requirements by selecting solvents that are free of aromatics and chlorine.

Anti-corrosion protective oils are available in different viscosities and with different levels of protection depending on their additive content.

Unlike solvent-based protective products, water-repellent protective oils do not evaporate and leave an oily film on the part, protecting it from oxidation and atmospheric attack. They can be applied with a paintbrush, brush, by immersion, or by spraying.

Their use is recommended for storage in warehouses and hangars, as well as during transport with suitable secondary packaging.

Water-repellent anti-corrosion oils can be easily removed using alkaline detergents or solvents. 

MotulTech offers aqueous concentrates to provide temporary protection against corrosion.

These products are generally used between two machining operations to provide short-term temporary protection. When diluted in water, they leave a passivating film that protects metals against corrosion.

This is an alternative to using an oil-based or solvent-based protective fluid to protect parts between two operations.

This more economical range improves working conditions in terms of hygiene and safety (barium-free, boron-free, formaldehyde-free, VOC-free).

• MT SOLV 

Barium-free, water‑displacing corrosion protection fluid, designed for short-term anticorrosion protection of metal parts during storage, handling, or intermediate manufacturing operations. It forms a nearly invisible protective film, which can be retained prior to assembly or welding operations.

• MT LIGHT OIL PROTECT

Low-viscosity, water-displacing anticorrosion oil, barium-free, suitable for temporary to medium-term corrosion protection of metal components, ensuring excellent spreading and surface coverage.

• MT OIL PROTECT

Medium-viscosity, water-displacing anticorrosion oil, barium-free, developed for temporary to medium-term protection of metal parts, providing durable corrosion resistance and reliable film strength.

• MT STORE  PROTECT

Water-displacing anticorrosion fluid, barium-free, intended for medium- to long-term protection of metal parts, particularly during extended storage or transportation.

• MT SHIP PROTECT

Long-term water-displacing anticorrosion fluid, barium-free, offering high-performance corrosion protection for metal parts in aggressive and corrosive environments, including marine transport and humid atmospheric conditions.

• SAFKLEEN 224

Water-based degreasing solution providing corrosion protection for ferrous metals. It leaves a protective film ensuring several weeks of corrosion protection, even at low use concentrations (2–5%), and is particularly recommended for inter‑operation protection or short-term indoor storage.
