In the marine shipping industry, maintaining clean and corrosion-free cargo holds is essential for operational efficiency, safety, and cargo quality. Ships carrying bulk materials such as coal, sulphur, salt, and fertilizers often face serious challenges due to corrosion, residue buildup, and difficult cleaning processes.
To overcome these issues, Dubichem Marine International has developed an innovative solution - Slip Barrier Coats HOLD BLOCK, a high-performance polymer-based coating designed to protect cargo hold surfaces and simplify post-discharge cleaning.
What is Slip Barrier Coats HOLD BLOCK?
Slip Barrier Coats HOLD BLOCK is a polymer-based, non-reactive coating that forms a thin protective film on cargo hold surfaces. This coating acts as a barrier between the cargo and the metal or painted surfaces of the ship hold.
Once applied and dried, it creates an inert and protective layer, preventing cargo from sticking directly to the surface and reducing the risk of corrosion and damage.
Why Cargo Hold Protection is Important
Bulk cargoes such as:
- Sulphur
- Salt
- Coal
- Petcoke
- Fertilizers
can be chemically aggressive or physically abrasive. When these materials come into direct contact with metal surfaces, they can cause:
- Rapid corrosion
- Surface degradation
- Paint damage
- Increased cleaning time
- Higher maintenance costs
Key Features and Benefits
1. Superior Corrosion Protection
- Acts as a barrier against corrosive cargo
- Prevents chemical reactions between cargo and metal
2. Easy Cleaning After Discharge
- Cargo does not stick to the surface
- Residues can be removed quickly with water or cleaning chemicals
3. Reduces Turnaround Time
- Faster cleaning means quicker vessel readiness
- Improves operational efficiency
4. Safe and Environmentally Friendly
- Non-toxic and non-reactive formulation
- Safe for use in enclosed areas
5. Protects Paint and Surface Integrity
- Prevents cargo penetration into coatings
- Maintains long-term durability of hold surfaces
6. Easy Application
-
Can be applied using:
- Spray systems
- Brush or roller
- Low-pressure equipment
Typical Applications
Slip Barrier Coats HOLD BLOCK is widely used in vessels carrying:
- Sulphur
- Salt
- Phosphates
- Urea
- Coal and Petcoke
- Cement
- Bauxite
It is especially useful for bulk carriers and cargo vessels handling corrosive or dusty materials.
Why HOLD BLOCK is Better Than Lime Coating
Traditionally, lime wash has been used for cargo hold protection. However, HOLD BLOCK offers several advantages:

HOLD BLOCK provides a modern, efficient, and cleaner alternative to traditional methods.
Application Method
Step-by-Step Process:
- Clean the hold surface - Remove old residues, dust, or lime deposits
- Apply HOLD BLOCK coating - Use spray or manual application and ensure uniform coverage
- Allow drying - Forms a thin protective film
- Load cargo - Cargo will not stick directly to the surface
- Post-discharge cleaning - Easily remove residues with water or alkaline cleaner
Recommended Dosage
Typical dosage depends on cargo type and vessel size:
-
Sulphur / Salt:
- Handymax: ~100 L per hold
- Panamax: ~150 L per hold
-
Coal / Petcoke:
- Handymax: ~200 L per hold
- Panamax: ~250 L per hold
One 210-liter drum can cover approximately 2000-2500 sq. meters on smooth surfaces.
Operational Advantages
Using HOLD BLOCK provides significant operational benefits:
- Reduces manual scraping and labor
- Minimizes cleaning chemical consumption
- Protects cargo hold structure
- Improves turnaround time between voyages
- Enhances compliance with cargo cleanliness standards
