The global intumescent coatings market size is expected to reach USD 1.31 billion by 2025.
Since Sherwin-Williams acquired Phoenix Fire Protection Group a year ago, its offices in Dubai and Hong Kong have been fully integrated into the organisation to offer the full range of products including corrosion protection coatings, tank linings, resin flooring, pipeline solutions and the Firetex range of passive fire protection intumescent coatings.
Besides the epoxy topcoat, the current engine cowling panel is also painted by a surface protection (epoxy primer) and a fireproof lacquer (intumescent coating), so these samples consist of the cowling composite panels sprayed with the current coating system (epoxy top coat/epoxy primer/intumescent coating), Cerakote only, Cerakote with both epoxy primer and intumescent coating, Cerakote with epoxy primer only, and epoxy primer and intumescent coating only.
The compatibility with PP and the effects of PBPP, PEPA, and PER on the water resistance, thermal degradation, flame retardancy of intumescent flame retardant of PP (IFR-PP) systems, and the IFR flame retardant mechanism were also been investigated by thermogravimetric analysis (TGA), UL-94 test, cone calorimetry test, Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM).
One type of functional coating is a fire-retardant variety (also known as an intumescent coating) to insulate steel substrates exposed to fire.
Jotun's range of Steelmaster intumescent coatings are among the most advanced in the world.
Intumescent coatings are inert at room temperature but when they are exposed to heat, they undergo a series of chemical reactions which can make the intumescent coatings swell up to 100 times of the initial thickness, forming a cellular char.
Intumescent fire-retardant coatings are widely used as a means to provide passive fire protection to steel structures due to their unique advantages, such as the ability to not modify the intrinsic properties of the materials, easy processing and the ability to be applied to several different materials.
The newly introduced intumescent paint and flame resistant coatings are suitable for structural building materials, such as stone, plaster and steel structures.
Among specific topics are the thermal properties of unsaturated polyester resin treated with intumescent flame retardants, micro-segregation behavior in a single crystal superalloy, a novel approach to determining the critical fracture strain of a near-alpha titanium alloy during hot compression deformation, the research status and prospects for solar hydrogen production, phonon interaction of ultrasound waves in condensed media, and analyzing the shock response of a marine gearbox.
This water-based thin film intumescent coating will provide a 15-minute thermal barrier over Spray Polyurethane Foam insulation.
Intumescent flame retardants are widely used in thermoplastic polyester elastomers; however, they are incompatible with polyesters, resulting in poor scratch resistance and scratch-whitening.
