VpCI-389 is a Water Reducible Temporary Coating developed for medium- to long-term corrosion protection in harsh outdoor and unsheltered environments. It is a fast-drying, water-based formulation that provides multimetal protection and strong resistance to salt exposure. The coating dries clear and forms a slightly tacky protective film that can be removed when equipment or components return to service. It can also be diluted with water, allowing application flexibility for different preservation requirements. VpCI-389 is suitable for machinery, fabricated metal parts, industrial equipment, stored components, overseas shipments, and equipment lay-up. Nassguard supplies VpCI-389 Water Reducible Temporary Coating throughout Qatar and Doha for outdoor storage, maintenance, transport, asset preservation, and corrosion-control applications.
More Details
Water Reducible Temporary Coating industrial equipment does not always go straight from production to installation. A pump may remain in a warehouse while a project is delayed. Fabricated steel can sit in an open yard awaiting transport. Spare parts may also spend weeks inside containers before reaching the final site.
During this waiting period, metal remains exposed to humidity, dust, condensation, fingerprints, and salt-bearing air. These conditions are especially relevant in Qatar and Doha, where equipment frequently moves between cool indoor areas and hot outdoor environments. The sudden temperature difference can leave moisture on unprotected surfaces.
VpCI-389 is a fast-drying Water Reducible Temporary Coating developed for metal parts, machinery, assemblies, and equipment that require removable protection in demanding outdoor conditions. It forms a clear, dry, slightly tacky film that offers multimetal protection and strong resistance to ultraviolet exposure. The coating can also be matched to selected custom colours.
Unlike permanent paint, this coating can be removed when the equipment is ready for assembly, inspection, welding, installation, or commissioning. Nassguard supplies VpCI-389 in Doha and across Qatar for construction equipment, oil and gas machinery, fabricated steel, marine assets, industrial components, export shipments, and long-term storage projects.
What is VpCI-389 Water Reducible Temporary Coating?
VpCI-389 is a water-based, removable coating formulated for harsh outdoor and unsheltered exposure. It provides temporary corrosion protection without leaving the heavy oily layer associated with traditional rust-preventive greases.
The product is applied as a liquid. Once the water evaporates, it leaves a clear protective film over the surface. This film is dry but slightly tacky, helping it remain attached to machinery and metal components during outdoor storage or transport.
VpCI-389 provides multimetal protection, making it useful for equipment containing more than one metal type. It also offers excellent UV resistance, which is important when coated parts remain exposed to sunlight for extended periods.
The coating can be applied by:
- Spray
- Brush
- Roller
- Dip application
It is described as water reducible because it can be diluted where technically permitted to suit the selected application method, required film build, and project conditions. The coating should be mixed thoroughly before use to achieve a uniform consistency.
When protection is no longer needed, the film can be removed using a suitable alkaline cleaner or degreaser. Tools and application equipment can be cleaned with water while the coating is still wet.

How Does VpCI-389 Work?
Rust forms when metal reacts with oxygen and moisture. Salt, industrial pollution, fingerprints, and chemical residues can accelerate this process.
VpCI-389 spreads over the prepared surface and forms a continuous barrier after drying. This coating limits direct contact between the metal and corrosive environmental conditions.
The film protects by reducing exposure to:
- Humidity
- Condensation
- Oxygen
- Chloride contamination
- Industrial dust
- Fingerprints
- Salt-bearing air
- Light chemical contamination
Its slightly tacky texture helps the coating stay attached during outdoor exposure. At the same time, the clear appearance allows workers to inspect the protected part without fully removing the film.
Good surface preparation remains essential. Grease, oil, loose rust, dirt, fingerprints, drawing compounds, and incompatible rust preventives can reduce adhesion and weaken the protective layer.
For bare metal, the technical data recommends commercial blast cleaning to NACE No. 3/SSPC-SP6 where appropriate. The surface should also remain above the dew point during application to prevent moisture from becoming trapped beneath the coating.
Applications Across Qatar and Doha
Oil and Gas Equipment-Pumps, valves, pipe fittings, skids, compressors, and mechanical spares may remain outdoors before installation. VpCI-389 can provide removable protection during this waiting period.
Construction Machinery-Excavators, cranes, generators, loaders, and other heavy machinery may stand outside between projects. The coating helps protect exposed steel and mechanical components from humidity and dust.
Marine and Port Operations-Equipment near Doha’s ports faces saline air and strong sunlight. The coating’s UV resistance and outdoor performance make it suitable for sheltered and unsheltered marine storage applications.
Fabrication Workshops-Fabricated steel sections, machined parts, frames, brackets, and assemblies may need protection before delivery to the project site.
Manufacturing Plants-Finished equipment can be coated before it moves into an outdoor storage area or enters the shipping process.
Power Generation Facilities-Mechanical spares, pumps, turbine-related components, and maintenance tools may require corrosion protection during shutdowns or long storage periods.
Automotive and Fleet Operations-Vehicle components, replacement parts, chassis sections, machinery attachments, and workshop equipment can receive temporary protection.
Warehouses and Open Yards-Even covered storage may expose metal to humid air and condensation. VpCI-389 offers stronger protection where basic packaging is not enough.
Export and Sea Freight-Equipment travelling in containers can face condensation, temperature changes, and coastal air. A temporary coating can support a broader export-protection plan.
Project Layup-Equipment placed on hold because of construction delays, procurement issues, or commissioning schedules can remain protected until work restarts.

Conclusion
Machinery and metal parts may face severe environmental exposure even before they begin operating. Outdoor yards, sea transport, coastal air, humidity, and temperature changes can all cause rust during storage.
VpCI-389 provides a removable protective layer for these demanding conditions. It is water based, fast drying, UV resistant, and suitable for harsh outdoor and unsheltered applications.
The coating forms a clear, slightly tacky film that stays on the surface during storage and handling. It can protect multiple metals and can be applied by spray, roller, brush, or dip.
When the equipment is ready for use, workers can remove the film with a suitable alkaline cleaner rather than stripping permanent paint.
