Following the Jotachar JF750, the mesh-free epoxy passive fire protection coating, Jotun has introduced the Jotachar 1709, a mesh free epoxy developed specifically for the hydrocarbon processing & energy industries.
Jotachar JF750 continues to be used by the offshore and onshore industries as an alternative to traditional mesh containing solutions for hydrocarbon pool and jet fire scenarios.
Jotachar 1709 has been manufactured to protect steel against hydrocarbon pool fire scenarios for up to four hours, as defined within the ANSI/UL1709 Standard. Benefits include long-term corrosion protection, reduced life-cycle costs and the elimination of any risk associated with mesh installation errors.
“Today, concrete or cementitious-based PFP materials are widely used in the hydrocarbon process and related industries to manage risks associated with pool fires,” explained John Warner, Jotun Category Manager (Intumescent Coatings). “Installation of lightweight cementitious material often includes welded or galvanised steel mesh systems, all of which add to cost, installation time whilst extending the shutdown period. Dense concrete options have a high installed weight, often requiring additional engineering considerations and are susceptible to deterioration if not correctly maintained. Whilst these PFP solutions may appear to have a low initial cost, they often deteriorate rapidly due to the harsh industrial environment, leading to extensive substrate corrosion with compromises in fire safety. Frequent inspection & extensive maintenance over the life of the asset is often required to ensure fire performance and steel integrity”.
By contrast, Jotachar 1709 can be applied in a continuous application process. “Our mesh free solution does not require additional welded pins, metal or fabric reinforcement, eliminating the need for complex mesh depth or overlap rules, reducing both material cost and installation time,” he continued. “Unlike concrete or cementitious-based solutions, Jotachar 1709 is highly durable and does not require additional weather-proofing to prevent deterioration. No topcoat is required as part of our UL1709 certification. For maintenance and repair, ease of application with Jotachar 1709 significantly reduces installation time, shortens asset downtime.”
