Delivering Safety and Endurance on Every Voyage

The global shipbuilding industry operates under some of the harshest environmental and operational conditions imaginable—constant exposure to seawater, humidity, vibration, and fuel residues. Whether building cargo ships, naval vessels, offshore platforms, or passenger liners, every surface must be engineered for strength, longevity, and safety.

At Junhui Technology, we specialize in advanced fire protection coatings and industrial (protective) paints designed specifically for marine and offshore environments. Our solutions combine high-performance corrosion resistance, fireproofing efficiency, and environmental compliance to ensure vessels and offshore structures remain safe, durable, and cost-effective over their entire service life.

Challenges in the Marine Environment

Marine structures and vessels face three persistent challenges:

1. Corrosion: Saltwater and high humidity continuously attack metal substrates, accelerating oxidation and material loss.

2. Fire Hazards: Fuel, lubricants, and confined engine spaces create a high risk of fire that can spread rapidly in the absence of protective barriers.

3. Mechanical and Chemical Stress: Waves, vibration, and exposure to chemicals during cleaning or operation cause continuous wear on protective coatings.

Junhui Technology’s coating systems are purpose-built to overcome all three—delivering reliable protection that meets international marine safety and performance standards.

Fire Protection Coatings: Vital for Ship Safety

Fire at sea is one of the most catastrophic incidents that can occur. In enclosed spaces such as engine rooms, cargo holds, bulkheads, and decks, temperature rise is rapid and firefighting access is limited. Junhui Technology’s marine-grade intumescent and cementitious fireproof coatings provide critical passive fire protection to contain such incidents.

How It Works

When exposed to heat above 200°C, our intumescent coatings react chemically to form an expanded, foam-like char layer—up to 50 times thicker than the original film. This char acts as an insulating barrier, slowing heat transfer to the steel substrate beneath and maintaining structural stability for extended periods.

Our cementitious fireproof systems, developed for heavy-duty offshore and shipyard applications, offer a dense mineral coating capable of withstanding hydrocarbon fires and jet flames. Together, these systems comply with IMO FTP Code, SOLAS requirements, and Lloyd’s Register / ABS fire safety certifications.

Applications

• Engine room bulkheads and ceilings

• Oil and fuel storage compartments

• Cable trays and control rooms

• Offshore accommodation modules and escape routes

• Decks and critical load-bearing structures

In each application, Junhui’s fireproof systems help protect lives, reduce damage, and ensure compliance with maritime safety regulations.

Industrial Protective Coatings: Defending Against Corrosion and Wear

Corrosion is the silent enemy of every vessel. Continuous exposure to seawater, atmospheric oxygen, and biological growth threatens both performance and profitability. Junhui Technology’s industrial protective coating systems are engineered to deliver long-term resistance against saltwater, chemicals, and abrasion—protecting hulls, tanks, and decks from deterioration.

Key Coating Systems

• Epoxy-based anti-corrosive coatings: Provide high adhesion and chemical resistance for ballast tanks, engine rooms, and cargo holds.

• Zinc-rich primers: Offer cathodic protection to prevent steel corrosion even in mechanically damaged areas.

• Polyurethane topcoats: Deliver outstanding UV stability, color retention, and gloss for external decks and superstructures.

• Antifouling coatings: Reduce marine growth and drag, improving fuel efficiency and lowering emissions.

• High-build, abrasion-resistant coatings: Suitable for splash zones and impact-prone surfaces like hull bottoms and offshore legs.

These coating systems not only preserve metal integrity but also enhance operational efficiency by reducing maintenance frequency and dry-dock intervals.

Technical Performance and Standards Compliance

Junhui Technology’s marine coatings are formulated and tested according to the highest international standards:

• IMO FTP Code (Part 2 & 3) – Fire resistance and surface flammability

• SOLAS Chapter II-2 – Safety of life at sea requirements

• ISO 12944 / ISO 20340 – Corrosion protection of steel in marine atmospheres

• NACE SP0108 – Corrosion control of submerged and splash-zone structures

• Lloyd’s Register & ABS Certification – Approved for ship and offshore use

All products undergo rigorous in-house testing for adhesion, impact resistance, salt spray, humidity, and accelerated aging—ensuring consistent, verified performance under the world’s most demanding conditions.

Coating Applications Across the Shipbuilding Process

Junhui Technology provides complete coating systems tailored to each phase of vessel construction and operation:

1. Hull & Underwater Areas

Our epoxy primer and antifouling systems protect the hull from corrosion and marine organism growth, improving fuel economy and reducing maintenance.

2. Decks & Superstructures

Using polyurethane topcoats and non-slip finishes, we ensure durability and safety for crew movement while maintaining aesthetic appeal.

3. Engine Rooms & Machinery Spaces

Intumescent coatings and epoxy systems safeguard steel components from fire exposure, fuel spills, and constant vibration.

4. Ballast & Cargo Tanks

Solvent-free epoxy linings provide chemical resistance against crude oil, fuels, and seawater, preventing contamination and corrosion.

5. Offshore Platforms

For drilling and production units, Junhui offers multi-layer protective systems that combine fire resistance, corrosion control, and UV protection—meeting offshore durability expectations.

Innovative Technologies for Modern Shipyards

Junhui Technology continuously invests in R&D and innovation to support next-generation shipbuilding. Our marine coatings incorporate:

• Nano-reinforced epoxy resins for enhanced barrier properties

• Self-healing polymers that close microcracks and prevent moisture penetration

• Low-VOC and solvent-free formulations to comply with environmental regulations and improve worker safety

• Smart coatings with embedded corrosion indicators for predictive maintenance

By integrating intelligent materials with advanced chemistry, Junhui Technology helps shipyards and fleet owners achieve longer service life, reduced emissions, and better operational efficiency.

Sustainability and Environmental Compliance

As global shipping moves toward decarbonization and greener operations, Junhui Technology supports the industry’s transition with eco-friendly coating solutions. Our products are compliant with IMO 2020, REACH, and VOC emission standards, contributing to safer shipyards and cleaner oceans.

Longer-lasting coatings also mean less frequent recoating, reduced solvent use, and minimized waste—helping clients meet both environmental and cost-reduction goals.
