THE SCIENCE BEHIND SEALS

orange compared to the earth

Marine innovation inspired by space

SEALS was created from the intersection of nanotechnology, aerospace-derived materials and a clear mission: to bring advanced marine protection and the most innovative boat coatings to the maritime sector.

The result is a unique product: durable, flexible, transparent, and eco-friendly

What is nanotechnology?

A nanometer is a unit of measurement in nanotechnology; it is as small as one billionth of a meter, To put that in perspective, if an orange were scaled up to the size of the Earth, a nanometer would be about the size of the original orange. At this microscopic scale, materials acquire extraordinary properties: extreme strength, water repellency, and chemical stability.

KEY MATERIALS

NANODIAMONDS

nanodiamonds particles

The hardest material in the world, enriched and scaled down to the nanometer level, providing scratch resistance and UV protection.

PHPS

PHPS molecule structure

The most durable transparent polymer, which cures at room temperature, ensuring 9H hardness and extreme longevity.

CNT

Carbon Nanotube

Ten times stronger than steel.

Adding flexibility and structural stability to the coating.

The combination of these elements creates an elastic, ultra-durable, anti-corrosion, water and oil-repellent protective film.

NANODIAMONDS

Invisible Protection, Visible Shine

Enriched nanodiamonds fill the micropores of boat surfaces, creating a continuous, smooth barrier.
Thanks to them SEALS: 

  • Repels water and contaminants thanks to super-hydrophobicity (contact angle up to 143°)
  • Prevents oxidation and corrosion
  • Increases abrasion resistance over ten times compared to standard gelcoats

PHPS

The Strongest Invisible Polymer 

PHPS is the hardest among transparent silicon-based polymers and naturally cures at room temperature.

This innovative material provides: 

  • Extreme hardness (9H) for maximum scratch and abrasion resistance
  • Chemical stability, resistant to salt, oxidizing agents, acids, and alkalis
  • Long-lasting UV protection to keep boat surfaces shiny
  • Anti-corrosion barrier that preserves the underlying structure even after prolonged saltwater exposure

Thanks to PHPS, SEALS coatings maintain their transparency and strength over time, offering a thin yet impenetrable protection for boats. 

CARBON NANOTUBES (CNTs)

Extreme Flexibility, Uncompromised Strength

Carbon nanotubes are cylindrical nanostructures, ten times stronger than steel yet extremely lightweight.

Integrated into SEALS coatings, they:

  • Enhance the flexibility of the protective film, allowing it to adapt to the vibrations and torsions typical of boating
  • Reinforce mechanical strength, making the coating more stable and long-lasting
  • Improve thermal stability, enabling protection to withstand extreme conditions without cracking or peeling

The result is a coating that combines hardness and resilience, capable of protecting surfaces even in the harshest marine and freshwater environments.

CERTIFIED PERFORMANCE

SEALS coatings have been tested and certified by SGS, a global leader in quality verification. They have passed the following tests: 

Pencil Hardness – ASTM D3363: maximum hardness (9H on 9H)

The Pencil Hardness test (ASTM D3363) evaluates a coating’s resistance to scratches by pressing pencils of increasing hardness against the surface. Our coatings achieved the maximum 9H rating, leaving no visible marks even under the hardest pencil. This matters because it proves the coating can withstand daily wear and mechanical stress, keeping boats and surfaces protected, smooth, and looking like new .

Chemical Resistance Test – Acid & Alkali Spot Test (ISO 2812-1, modified): Our coating demonstrates excellent resistance to both acidic and alkaline substances, maintaining its integrity and appearance even when exposed to harsh chemical spots.
