Jotun launched Jotachar JF750, the passive fire protection (PFP) coating system which they say significantly reduces installation time and cuts material costs.
Following an extensive development and testing program, the launch of Jotun’s new mesh free PFP helps owners, fabricators and applicators save time, lower costs and reduce risks compared to systems that require mesh reinforcement.
According to Andy Czainski, Jotun’s Global PFP Sales Director, Jotachar JF750 is the only mesh-free epoxy intumescent coating solution available to the market where jet fire protection is required for safety critical steel structures, divisions and vessels. A majority of offshore assets require some degree of jet fire protection, with many onshore owners now also demanding PFP materials that can demonstrate Jet fire capability to ISO 22899. “The formulation of Jotachar JF750 incorporates an advanced fibre matrix system in the material” he explained. “This technology, combined with a robust and temperature stable insulating char, eliminates the need for additional mesh reinforcement, reducing complexity and making it significantly faster to apply, hence saving time and cost.”
Jotachar JF 750 has been extensively and independently fire tested to all key industry standards, demonstrating structural fire protection for up to three hours. Steel sections and divisions are tested to the industry recognized ISO834/BS476 Part 21 “hydrocarbon curve”, proving protection from hydrocarbon pool fires. Importantly, Jotachar JF750 also demonstrated exceptional jet fire performance in the ISO 22899 test without additional mesh reinforcement for up to two hours. This ISO standard simulates the highly erosive, high heat flux and rapid temperate rise experienced within a jet fire. JF750 has been tested and passed a four bar blast overpressure, again without any need of additional reinforcing mesh.
Czainski stated that “All fire and blast resistance testing has been witnessed by Lloyds Register. Witnessing of testing by a major classification society, in additional to endorsement of our third party fire assessments undertaken by Exova Warrington Fire, is a prerequisite for product Type Approval from Lloyds Register, DNV and other major classification societies”.
