PETRO VIETNAM Paint to Commercialise Protective Coating Range Incorporating ecosparc®

👉 https://t.co/ItUqc9hYfz

"PV PAINT has chosen to incorporate ecosparc® within an existing commercial coatings range... this international product release is clear evidence of growing momentum behind the use of ecosparc® to enhance the performance and longevity of steel protective coatings." - Nick O'Loughlin, Managing Director

Vũ Duy Cường, General Director, PV PAINT, commented:

"As part of our strategy focused on innovation and technological self-reliance, PV PAINT began researching the application of graphene in protective coatings in 2021 and achieved encouraging results, culminating in the launch of the PERAPHENE product range in January 2025.

Since then, we have continuously evaluated graphene materials from around the world with the objective of optimising both performance and cost-effectiveness. ecosparc® has been assessed as the graphene additive that best meets our product requirements at this point in time.

In addition to our internal testing programs, we submitted coating systems incorporating ecosparc® to independent laboratories for evaluation. The results have been very positive. These new coating systems satisfy the requirements of the C5-High corrosivity category under ISO 12944-6 while achieving this performance at lower dry film thicknesses than comparable coating systems currently recommended by the company.

We are continuing to evaluate coating systems incorporating ecosparc® under even more demanding service conditions, including C5 Very High, CX, offshore and immersion environments, with the objective of achieving equivalent or improved performance at lower dry film thicknesses than existing products serving the same applications. We are looking forward to sharing these results with Sparc in the near future.

Based on the results achieved to date, we are confident that ecosparc® is fully capable of meeting the demanding performance requirements of our PERAPHENE-branded protective coating systems intended for highly corrosive environments.”

Very good news! HydroGraph Clean Power $HG / $HGRAF gaining momentum in the world of Graphene.

[Sparc Technologies (ASX:SPN) @SparctechS]

We have entered into a Letter of Intent with HydroGraph Clean Power Inc. to evaluate the use of its Fractal Graphene within ecosparc®️ additives for protective coatings.

Initial testing in water-based systems has demonstrated encouraging performance, supporting further evaluation in solvent-based coatings under ISO 12944 corrosion testing standards.

This collaboration provides access to a high-quality graphene supply partner as we continue advancing the commercialisation of ecosparc®️, with further milestones expected in H1 2026.

How do massive porphyry deposits like Mocoa form?

It all comes down to time—millions of years of heat, fluids, and evolving mineralization.

Watch now to see why Mocoa’s 10-million-year hydrothermal window matters — and what recent drill holes are revealing.

Copper Giant extends mineralization by 250 meters. They already have 12.7 billion pounds of copper equivalent. Their market cap is just US$43 million. Still looks undervalued to me.

[Copper Giant @Cu_Giant]

NEWS — DECEMBER 11, 2025 — Copper Giant Extends the Recently Discovered Third High-Grade Zone at Mocoa by 250-metres along strike with MD-052 intercepting 208-metres grading 0.68% CuEq* (0.47% Cu and 0.04% Mo), starting at 768-metres

“MD-052 builds directly on the success of MD-047 and MD-050, extending the recently discovered third high-grade zone and reinforcing the geometry of this emerging porphyry center.

The zone remains open laterally and at depth, supporting continued improvements to the copper and molybdenum grade profile.

These results demonstrate strong continuity of mineralization and meaningful potential for future resource growth within this multi-phase system.

Notably, the high-grade trend also projects southward toward the La Estrella target, indicating potential extension of this zone into a shallower area and opening an important new front for expansion,” said Edwin Naranjo Sierra, Vice-President of Exploration.

Two drill rigs continue operating as part of Copper Giant’s 14,000-metre resource expansion program at Mocoa.
