Description
INTUMESCENT FIRE-RETARDANT COMPOSITION
FOR HIGH TEMPERATURE AND LONG DURATION PROTECTION
FIELD OF THE INVENTION
The present invention relates to a fire-retardant coating that is applied to many organic and inorganic substrates to provide fire protection by reducing the flame spread and reducing the heat transmission. More particularly, the new and improved fire-retardant coating composition is designed for use in severe applications for protection of the substrate where there is exposure to high temperatures or to fire for long duration or to substrates like plastics and composites with relatively low melting or ignition temperatures.
BACKGROUND OF THE INVENTION
Intumescent materials have been known for many years and have been used as coatings to provide thermal protection up to approximately 2,OOO~F. Substrates, such as wood, various metals, such as steel, aluminum, etc., and various types of plastics, such as PVC, thermoplastics, and epoxies, have been coated to make them more fire-retardant.
However, an intumescent coating applied to these aforementioned substrates is impractical where the coating is subjected to severe physical and environmental conditions.
In addition, with the increased use of wood and wood by-products and the proliferation of new types of wood composites for use in home and office construction applications, and composites of plastics and other organic materials, current intumescent fire-retardant coating compositions do not provide adequate protection from fire and heat for a prolonged time period. Currently, there is no SUBSTITUTE SHEET (RULE 26) single intumescent fire-retardant coating material having all of the following features:
1. Reduction of available oxygen in confined areas, such as a room, to smother the fire and to retard the fire in the advent of a flashover;
2. Providing a low rate of thermal transmission for coatings to protect various substrates, especially where low weight and low cost are critical, such as in aircraft and ships.

3. Providing an effective intumescent fire-retardant coating for low density wood by-products, composite wood andplastic materials which require zero flame spread for prolonged time exposure during a fire.
4. Sufficient mechanical properties and durability, to resist abrasion, impact and severe weather.
5. Non-toxic before it is exposed to heat, and the combustion products emitted upon exposure to heat, are below the gas level emissions required by today's transportation standards.
Also, in many applications of an intumescent fire-retardant coating to substrates such as wood, PVC, thermoplastics, aluminum and epoxies, coatings are impractical for reasons other than fire protection, as they lack abrasion resistance, impact resistance, water resistance, and resistance to other environmental factors.
Because of these factors, present coatings do not provide protection from fire and heat for a sufficient time duration during a fire, and are not durable enough to last sufficiently long to make them cost effective.
There is a need for a new and improved intumescent fire-retardant coating material that would provide substantial protection from fire and heat for a long duration if a fire were to occur. The coating material should be useable on a variety of substrates such as iron, steel, stainless steel, aluminum, and other non-ferrous metals, wood, plywood, particle board, and other wood by-products, plastics, PVC, thermoplastics, epoxies, and composites.

wrappings, wall barriers and the like.
Another example of a typical application would be the coating of structural steel, columns, beams, steel decking, bar joists, hung ceilings for construction of commercial buildings, high-rise office buildings, high rise apartment complexes, bridges, tunnels, and the like.
A further example of application would be the transportation industry where the fire-retardant coating material would be used in autos, buses, trucks, cargo ships, and airplanes; for coating of vehicular undercarriages, exhaust systems, gas tanks, fire walls, engine compartments, catalytic converters, hoods, cargo liner patches, airport loading bridges, and the like.
Still another example of application would be in the marine industry where the coating material would be used on bulkheads, piers, cabinet penetration barriers, cables, conduits, cargo areas, and offshore drilling platforms.
A still further example of application would be in the telecommunications, utilities, petroleum, and chemical industries where the coating material would be used on cable wrap and coating, conduit wrap, communication towers, fire penetration barriers, seals, pipeline wraps, storage tanks, reactors, ovens, distillation columns, furnaces, and the like.
