OCSiAl, PV PAINT, and Mercury Chemical are collaborating to implement OCSiAl’s TUBALL™ single-wall carbon nanotube (SWCNT) technology in high-performance anti-corrosion coatings, enabling zinc optimization while maintaining protection at the CX corrosivity level under ISO 12944.

On July 20, 2026, representatives of OCSiAl, PV PAINT, and Mercury Chemical met at the PV PAINT manufacturing facility to review research and testing results and discuss the further development and commercialization of anti-corrosion coating systems based on TUBALL™ technology.

During the meeting, PV PAINT presented its testing results for TUBALL™ MATRIX 203 in nano-carbon coating systems. The results demonstrated the potential of OCSiAl’s SWCNT technology to enhance coating performance while creating opportunities to optimize the zinc content of the formulation. OCSiAl and Mercury Chemical will continue working with PV PAINT to provide technical support during further development.

The key advantage of the technology is the ability to enhance the protective efficiency of the coating system through SWCNTs rather than relying solely on higher zinc loading. When properly dispersed, TUBALL™ SWCNTs form a reinforcing nano-network within the coating film at very low concentrations, contributing to improved adhesion, crack resistance, and coating durability. This enables the formulation of high-performance protective coatings with optimized zinc content while maintaining strong corrosion protection.

This technology has also supported PV PAINT’s development of the PERAPHENE™ range, including zinc-rich coating systems enhanced with TUBALL™ SWCNTs. According to OCSiAl, these products are being developed for demanding applications such as offshore oil and gas facilities, petrochemical plants, storage tanks, steel structures, and marine infrastructure.

Importantly, the solution is designed to meet the CX corrosivity level – the highest corrosivity category defined under ISO 12944 – making it suitable for extremely demanding industrial and marine environments. Achieving CX-level corrosion protection while optimizing zinc content represents a significant advantage, as zinc remains an important component of the electrochemical protection mechanism in zinc-rich coatings while also being a material that needs to be used more efficiently as sustainability requirements increase.

From an environmental and ESG perspective, reducing zinc consumption while maintaining high corrosion-protection performance can help optimize raw-material usage, improve coating efficiency, and potentially extend maintenance intervals over the service life of industrial assets. This reflects a broader transition from using more material to achieve higher performance toward improving material efficiency through nanotechnology.

During the visit, the OCSiAl delegation, PV PAINT, and Mercury Chemical also discussed manufacturing processes, quality control, and the potential to scale TUBALL™ applications from laboratory development to industrial production.

The cooperation between OCSiAl – developer of TUBALL™ SWCNT technology, PV PAINT – an industrial protective-coating manufacturer, and Mercury Chemical – OCSiAl’s official distributor in Vietnam – represents a direct three-party collaboration to bring advanced nanotechnology into practical anti-rust and anti-corrosion solutions in Vietnam.

With TUBALL™ SWCNT technology, the objective is not simply to develop a better anti-corrosion coating, but to optimize zinc utilization, achieve CX-level protection under ISO 12944, and develop coating systems that are more material-efficient and aligned with ESG objectives.
