Denso Protal 650 in Riyadh | Denso Protal 650 Supplier in Riyadh

Denso Protal 650 CTR™ is a two-part polyamide coating developed as a replacement for traditional coal tar epoxy. It protects steel and concrete substrates against water and seawater corrosion while providing a high-build coating in one application. The product offers a non-carcinogenic alternative to coal tar epoxy for suitable corrosion-protection projects. Nassguard supplies Denso Protal 650 in Riyadh and across Saudi Arabia, including Dammam, Jubail, Jeddah and Al Khobar.

What Is Denso Protal 650 CTR™?

Denso Protal 650 CTR™ stands for Coal Tar Replacement. It uses polyamide chemistry to provide an alternative to hazardous coal tar epoxy coatings.

The two-part coating protects suitable steel and concrete structures against water and seawater exposure. Its high-build formulation can achieve 400–660 µm in one coat, while the coating reaches touch-dry condition in approximately 3 hours at 25°C.

Workers can apply Protal 650 CTR by brush or spray. The coating suits applications where engineers would traditionally consider coal tar epoxy, including steel piles, sheet piles, lock gates and reservoirs.

How Denso Protal 650 CTR™ Works

Denso Protal 650 CTR creates a protective coating over the prepared steel or concrete surface. The coating separates the substrate from water and seawater exposure.

Its polyamide chemistry provides the properties needed for applications where coal tar epoxy would traditionally provide corrosion protection. The high-build formulation also allows workers to achieve 400–660 µm in one coat.

Surface Preparation and Application

Proper surface preparation helps the coating achieve reliable adhesion and long-term performance.

• Prepare the steel or concrete substrate according to the project specification.
• Remove rust, scale, dirt, grease and other contamination.
• Use the specified surface-preparation method for the selected substrate.
• Ensure the prepared surface meets the required cleanliness and profile.
• Mix the two components according to the manufacturer’s application procedure.
• Apply the coating by brush or spray.
• Build the coating within the required 400–660 µm range.
• Allow the coating to reach its required drying condition before handling.
• Inspect the finished coating for missed areas and visible defects.
• Follow the project requirements for coating thickness and application conditions.

Water and Seawater Corrosion Protection

Water can accelerate corrosion on exposed steel structures. Protal 650 CTR creates a protective barrier that helps separate the substrate from water and seawater.

The coating suits selected applications where structures face continuous or repeated water exposure. Its resistance to water and seawater, combined with its hardness, flexibility and adhesion, supports demanding corrosion-protection work.

Coal Tar Epoxy Replacement

One of the main advantages of Protal 650 CTR is its role as a coal tar replacement.

Traditional coal tar epoxy systems can present health and environmental concerns. Protal 650 CTR uses polyamide chemistry to provide an alternative for suitable applications that previously relied on coal tar epoxy. Denso describes it as a non-carcinogenic replacement for coal tar epoxy.

High-Build One-Coat Application

The coating can achieve 400–660 µm in one coat. This high-build capability can reduce the number of application stages when the project specification allows a one-coat system.

Denso also states that Protal 650 CTR becomes touch dry in approximately 3 hours at 25°C. Actual drying conditions can vary with temperature, humidity, substrate condition and application conditions.

Brush and Spray Application

Workers can apply Denso Protal 650 CTR using either a brush or spray.

Brush application can suit smaller areas and detailed sections. Spray application can help cover larger surfaces efficiently when the equipment and site conditions meet the coating requirements.

The application method should match the project specification, surface condition and required film thickness.

Storage and Handling

Store the product according to the manufacturer’s current technical and safety documentation. Keep the components in suitable storage conditions and protect the containers from excessive heat, moisture and contamination.

Workers should use suitable personal protective equipment during mixing and application. Provide adequate ventilation and follow the applicable workplace safety procedures.

Choosing Denso Protal 650 for Your Application

Before purchasing Denso Protal 650 in Riyadh, consider the substrate, environment and required coating system.

• Confirm that the substrate consists of suitable steel or concrete.
• Assess exposure to water or seawater.
