VCI Liquid Additive water-based coatings offer several practical benefits, but corrosion can still create problems during storage, application, and long-term service. A paint may begin rusting inside the container, or a coated steel surface may show corrosion around scratches and exposed edges.

M-119 / M-119LV Liquid Additive helps address those issues from inside the coating formulation. It is a VCI Liquid Additive for water-based epoxies, urethanes, acrylics, and alkyds. Manufacturers add it directly to compatible coating systems to improve corrosion protection for carbon steel and aluminium. The additive also helps control in-can corrosion and reduces corrosion spread around damaged coating areas.

For businesses looking for a VCI Liquid Additive in Qatar, M-119 and M-119LV can support industrial coating production, maintenance paints, metal fabrication, machinery protection, and water-based coating development. Nassguard supplies M-119 / M-119LV to customers throughout Doha and Qatar.

What is M-119 / M-119LV Liquid Additive?

M-119 is a water-based corrosion inhibitor designed for compatible waterborne coating systems. It works with several commonly used coating types, including water-based Epoxies, Urethanes, Acrylics, Alkyds

The formulation protects both carbon steel and aluminium. It also combines direct-contact corrosion control with vapor-phase protection. M-119LV performs the same basic job but uses a lower-viscosity blend. This makes it easier for paint manufacturers to introduce the additive into certain formulations.

Both versions avoid heavy-metal corrosion inhibitors such as zinc phosphate, chromates, and barium according to the manufacturer’s current product information.

What is the Difference Between M-119 and M-119LV?

The main difference lies in handling and viscosity. M-119 provides contact and vapor corrosion inhibition for water-based coating systems. M-119LV provides similar protection but comes in a lower-viscosity formulation, which can make blending easier during paint production.

The manufacturer also notes that M-119LV can work together with M-380 at a 3:1 ratio of M-380 to M-119LV. The same general combination applies to M-119. Each additive should enter the coating separately.

Uses of M-119 / M-119LV Liquid Additive

These additives mainly serve paint and coating manufacturers rather than acting as stand-alone rust preventatives.

• Water-based epoxy coatings
• Waterborne urethane coatings
• Acrylic coatings
• Alkyd coating systems
• Industrial maintenance paints
• Metal primers
• Protective coatings
• Machinery coatings
• Fabricated steel coatings
• Aluminium coatings
• Equipment paints
• Industrial repair coatings
• Water-based metal finishes
• Factory-applied coatings
• General corrosion-control formulations

Their usefulness becomes clear when a water-based coating needs additional corrosion protection without moving to a heavy-metal inhibitor package.

Key Features of M-119 / M-119LV

Protects Carbon Steel and Aluminium-Both products target two widely used industrial metals: carbon steel and aluminium. That makes them useful for coating manufacturers supplying fabrication, machinery, maintenance, transport, and general industrial sectors.

Works in Contact and Vapor Phases-The inhibitor does not rely only on direct contact. Part of the corrosion protection comes from the coating-metal interface, while vapor-phase action can help protect nearby exposed surfaces in enclosed areas. This gives the coating another layer of protection around edges, cavities, seams, and partly enclosed metal sections.

Helps Control In-Can Corrosion-Water-based coatings can sometimes attack metal packaging or experience corrosion-related problems during storage. M-119 and M-119LV help reduce in-can corrosion, which can improve the stability of the finished coating during storage.

Reduces Scribe Creep-Small scratches can expose the metal underneath a coating. Once moisture reaches that area, corrosion may begin to spread under the paint film. The manufacturer specifically states that M-119 and M-119LV help reduce scribe creep, making them relevant for protective coating formulations exposed to scratches or coating damage.

Free From Certain Heavy-Metal Inhibitors-The current product pages state that these additives do not contain zinc phosphate, chromates, or barium. This can help formulators who want to move away from some traditional heavy-metal corrosion inhibitor chemistries.

M-119LV Offers Easier Incorporation-The lower viscosity of M-119LV gives formulators another practical advantage. It can mix more easily into compatible water-based coating systems, particularly where viscosity control matters during production.

Applications Across Qatar and Doha

Applications in Qatar

Coatings used in Qatar often face demanding environmental conditions.

Humidity, coastal salt, temperature changes, and outdoor exposure can increase corrosion risk on steel structures, aluminium equipment, machinery, fabricated components, and maintenance surfaces.

M-119 / M-119LV can support coating manufacturers serving:

• Oil and gas facilities
• Petrochemical plants
• Steel fabrication
• Aluminium fabrication
• Industrial maintenance
• Machinery manufacturers
• Equipment repair companies
• Protective coating suppliers
• Engineering workshops
• Industrial painting contractors
• Manufacturing plants
• Marine-support companies

For example, a water-based primer used on fabricated steel may look good after application but still need added protection around scratches or damaged areas.

Adding a corrosion inhibitor to the coating formulation can help strengthen this weak point.

Applications in Doha

Businesses in Doha use water-based coatings across machinery, equipment, structural components, fabricated steel, aluminium parts, and maintenance projects.

A coating manufacturer may want to improve the corrosion resistance of a waterborne acrylic or epoxy without changing the complete formulation.

In that situation, M-119 or M-119LV can provide a practical formulation route.

The LV grade becomes particularly useful when easier mixing and lower additive viscosity are priorities.

Nassguard supplies M-119 / M-119LV Liquid Additive to coating manufacturers and industrial customers across Doha and Qatar.

The manufacturer’s current coating-additives page gives a general recommended usage range of 0.5–2% for both M-119 and M-119LV, so formulators should confirm the final amount through their own production testing.

How to Add M-119LV to a Coating?

The M-119LV technical sheet gives several incorporation options. For a water grind without resin, manufacturers can add it after the wetting agent and co-solvents. If the grind contains resin, they can introduce M-119LV into the resin before adding the other components. During let down or final adjustment, manufacturers can add the product using moderate to high agitation. This flexibility helps paint formulators choose the most practical stage for their existing production process.

Certifications, Standards and Compliance

M-119 and M-119LV work as additives inside complete coating formulations.

For this reason, manufacturers normally test the finished coating, not just the additive, against corrosion and coating-performance standards.

• ASTM B117 – Salt Spray Corrosion Testing
• ISO 9227 – Salt Spray Testing
• ASTM G85 – Modified Salt Spray Testing
• D3960 – VOC Content of Paints and Coatings

These standards provide useful methods for evaluating corrosion resistance, coating performance, and formulation properties. They should not automatically be described as individual certifications of M-119 or M-119LV unless supporting certificates or reports confirm that status.
