FIRE SEAL is a water based intumescent fire retardant latex coating for interior and exterior (top-coating required) applications. When subjected to fire, it swells 60 to 100 times than that of its original thickness forming a stable and inert carboneous char which forms a physical barrier between the flame and the substrate. This char thermally insulates the substrate from heat and stops the availability of oxygen required for fire initiation. It provides effective heat shield and insulation to the substrates. It provides fire protection to most metallic and non-metallic substrates.

Salt Spray Test for 10 days. System comprising one coat of Anticora EZP 500 Epoxy Zinc Phosphate Primer and two coats of Fire Seal.
No signs of blistering and corrosion observed.
Surface Preparation :
No special surface preparation is required. The surface should be clean and dry, free of dirt, oil, loose scales or paint and other foreign matter. On porous surfaces or flaky rusty surfaces, loose flakes and / or rusty scales must be removed by scraping and a proper surface suitable for application of the coating restored. Coating on the primed surfaces must be sanded and / or primed or removed prior to painting. Apply one coat of Anticora EZP 500 : Epoxy Zinc Phosphate Primer and allow it to dry for 24 hours.
Application Procedure :-
Due to possible settling of pigments during shipping and storage, the product should be thoroughly mixed. Do not mix water into the paint. If at all required, water to the tune of 5% maximum can be added. Apply a coat of Fire Seal liberally so that dry film thickness of 250 microns is achieved and allow it to cure for 24 hours. Apply second coat of @ 250 microns dry film thickness and allow the same to dry. The total DFT being 500 microns minimum.
Fire Seal can be top-coated with latex paints and two-component polyurethane paints for exterior applications.
Fire Test :-
Plywood panels of size 30x30x1 cm were painted with two coats of FIRE SEAL paint at dry film thickness of 250 ± 10 microns per coat and the total dry film thickness being 500 ± 20 microns. The test was carried out with the help of two feet tunnel equipment. A flame from a gas burner was applied to the coated plywood panels for 10 minutes. The temperature of the flame being 1400°C. The panels were examined for height of intumescence formation. Further the char was removed to find out whether there is any damage to the plywood surface.

Apart from the above test, Intumescent property of FIRE SEAL coating was further proved by putting on flame the wooden huts coated with two coats of FIRE SEAL coating and the huts coated with conventional fire retardant paint. (See picture below). The huts are burnt by igniting 300 ml of alcohol kept inside the huts. After the test, the FIRE SEAL coated huts were examined for any damage to the structure.
Performance of FIRE SEAL Intumescent coating after 15 minutes flame test. Left Hut is coated with Fire Seal & the right hut is coated with conventional fire retardant paint. It is seen from the picture that the left hut coated with Fire Seal is not damaged at all even after 15 minutes but the right hut coated with conventional paint is reduced to ashes.
FIRE SEAL can be applied to most metallic and non-metallic surfaces like steel, aluminium, wood, plyboard, plastics, electrical cables, and any surfaces that require protection from fire.
