Time saving solution
Jotachar’s mesh free solution provides significant benefits for owners, fabricators and applicators compared to systems that require mesh reinforcement:
- Increased productivity
- Installation time reduced with up to 50%
- Maintenance cost reduced
- Saves material costs with up to 50%
- Less risk
- Potential one-coat system for 30 or 60 minute jet fire scenarios
Jotachar JF750 is the only mesh free epoxy intumescent coating solution available to safeguard critical steel structures, divisions and vessels in a jet fire.
Mesh containing systems require a larger installation crew to complete the project, and more frequent inspections to ensure the complex mesh overlap and depth rules are in compliance with product- and project certification rules. These factors will add time and cost to any project.
Continuous application
Faster project completion
Less downtime, no mesh inspection points
Up to 50% reduction in time and costs
Increased productivity, no mesh installation
One-coat system

Mesh free
Until the introduction of Jotachar JF750, the industry was dependent on epoxy PFP systems that require additional mesh reinforcement to protect assets that may potentially be exposed to explosions, jet fires or hydrocarbon fires.
To avoid any risk of failure when exposed to fire, mesh reinforcement must be correctly installed according to the product’s certification. The consequences of incorrectly installed mesh could be devastating, leading to loss of life, loss of asset, environmental catastrophe and huge financial impact on the asset owner.
Mesh free Jotachar JF750 not only avoids these risks but brings the added benefits of lower life cycle cost, lower maintenance cost and faster project completion.Jotachar advantages versus mesh containing PFP
No mesh depth rules to follow
Left: mesh embedded at the correct depth in the coating Right: mesh embedded too close to the coating surface
Certification rules dictate that mesh reinforcement must be installed at a specific depth within the PFP coating, typically at the middle. If the mesh is not installed at the correct depth, the system will not meet these requirements.
No epoxy PFP detachment from the mesh layer
Poor installation of mesh with mesh exposed and detachment of the final coat
Incorrectly installed mesh reinforcement can significantly reduce the cohesive properties between the mesh and the final coat of epoxy PFP. This can lead to detachment and system failure in a fire scenario. Jotachar JF750’s continuous mesh free application eliminates this risk.
No complicated repairs or upgrades
1. Damage repair required 2. Remove PFP back to primer and step back 2nd coat of PFP to expose sound mesh layer 3. Apply 1st coat of PFP and apply new mesh 4. Apply 2nd coat of PFP and then topcoat
Mesh containing systems can be difficult to repair as the replacement mesh layer has to follow the same certification rules as the initial layer. This means cutting back to expose undamaged mesh and overlapping with a new mesh layer. If a fire scenario upgrade is required, the mesh should be completely removed and replaced in accordance with the certification rules.
Mesh incorrectly installed or omitted
Lack of overlap of mesh results in unpredictable fire performance
The mesh reinforcement must be installed in accordance with strict certification rules depending on fire scenario. It is very difficult to observe if the mesh has been installed correctly or installed at all. Incorrect overlaps or lack of mesh will result in unpredictable fire performance.
No water ingress at mesh terminations
Mesh strands exposed – offering a route for moisture to enter the coating
If system terminations are not completed correctly, mesh strands can protrude from the termination point. These exposed strands provide a path for moisture into the coating, leading to poor adhesion, water uptake and reduced fire performance through the life of the system.
No mesh detachments from overlaps
Poor adhesion at mesh overlaps – the result of incorrect installation and the source of delays and reworking
At mesh joints an overlap must be introduced according to certification rules. If the overlapping mesh is not correctly installed with adequate adhesion, the upper layer of mesh will lift. This will cause project delay due to rework of the mesh and the subsequent coats.

Durability
Jotachar JF750 is pre-qualified to NORSOK M-501 Edition 6, considered to be the industry’s most rigorous test standard to ensure corrosion resistance, material durability and mechanical performance.
Importantly, NORSOK M-501’s post weathering fire testing demonstrates that Jotachar JF750 has no reduction in fire performance after the rigorous ISO 20340 cyclic durability test. These standards provide operators with confidence that fire performance and excellent corrosion protection are assured, even after many years of exposure in severe offshore environments.
As a result, Jotachar JF750 shows a significant reduction in overall life cycle cost.
