Fuel Tank Protection with PROBOND
Heavy-duty haulage operators have discovered a unique use for PROBOND High Strength Bonder & Sealer — applying it as a protective coating to the ends of metal fuel tanks that are exposed to road debris, corrosion, and impact damage.
Unlike traditional sealants, PROBOND forms a tough, flexible, and permanent layer that resists vibration, chemicals, and moisture — perfect for environments where mechanical wear and corrosion are constant concerns. It can be used to bond, seal, or protect metal and plastic surfaces in even the harshest industrial conditions.

Real-World Industrial Application
One national road haulage company now coats fuel tanks with PROBOND Black . Once cured, the layer provides long-term corrosion protection and impact resistance without the need for additional paint or coatings. The result is a cleaner, safer, and more durable finish that extends component lifespan and reduces maintenance costs.
- Protects fuel tanks from corrosion, salt, and road impact
- Remains flexible under vibration and temperature change
- Creates a waterproof and chemical-resistant barrier
- Adheres to bare, painted, or primed metal surfaces
ProBond can also be used for fuel tank repairs, leak sealing, or general bonding of metal, plastic, and composite materials.

Paintability
This MS polymer-based bonder and sealer can be painted immediately after skin formation, ensuring a clean and professional finish.
- Lightly sand the cured surface with a Scotch-Brite® pad
- Degrease thoroughly before painting
- Apply compatible paint directly after preparation
Note: Synthetic paint systems may dry more slowly.
Cleaning & Surface Preparation
For the best bond performance:
- Ensure all surfaces are clean, stable, and grease-free
- Remove loose dust or particles with a brush
- Degrease with a suitable cleaner
- Apply between +5°C and +40°C
- For highly porous materials, test adhesion or use a primer if required
Clean tools and surfaces immediately after use. Once cured, PROBOND can only be removed mechanically.
Environmental and Safety Information
- Free from solvents, isocyanates, and silicone
- Low-VOC, odourless, and non-toxic
- Complies with EMICODE EC1 PLUS and VOC Class A+ standards

How to Apply the PROBOND High Strength Bonder and Sealer
Step 1 – Preparation
Clean and dry surfaces (or slightly damp if required). Ensure stability and remove dust, grease, and loose particles.
Step 2 – Application
Apply PROBOND in vertical beads using a standard caulking gun. Maintain spacing of 10–20 cm for ventilation.
Step 3 – Tooling
Tool the bead before skin formation (~10 minutes). For sealing, smooth with a suitable tool or spatula.
Step 4 – Curing
Allow curing under ambient conditions. Full cure depth 2–3 mm per 24 hours at 23°C / 55% RH.
