Fire-Retardant Coatings

Introduction                                              
 
The very thought of fire grips the mind with fear and panic. Overwhelming heat, suffocating smoke, loss of property, and above all else, the loss of life. The insurance company may be able to replace the material goods, but there are some things that money simply cannot replace – lives, lost time and items of sentimental value.Fire strikes when least expected. It can start just about anywhere without warning, taking one by surprise and causing panic.  

Fire is a serious treat in our everyday lives – in our homes, the work place and even when we travel. On the other hand, paint is used everywhere, to decorate and to protect against the elements and corrosion. However, regular paints are flammable and help in the spread of a fire even on a non-flammable surface such as steel. Further, fire weakens a structure and can lead to its collapse. Thus the need arises for sophisticated fire-retardant coatings to prevent the spread of fire and to protect the structure from permanent damage.

 Today organisations are rapidly realising the importance of fire-retarding paints. To cater to this demand, Noble Paints offers ‘Fyretard’ fire-retardant paint and ‘FyrePruffe’ intumescent coating – two immensely effective coatings that provide the ultimate in fire protection to industries, corporate houses, residences, institutions, etc.    

Fyretard

Noble Paints was commissioned by the Indian Navy in 1975 to paint its indigenously built frigates, the result – ‘Fyretard’, India’s first fire-retardant paint.

 As the name suggests, it is a fire-retarding paint. It consists of  a non-flammable base and special additives. Unlike normal paints which are flammable and aid in the spread of fire, Fyretard prevents the spread and localizes the fire giving you time to seek help  A small fire is easier to fight than an out-of-control blaze and the physical and financial damage done is far less.
 
 On metal, normal paint tends to burst into flames even if not subjected to a flame directly. This is because the intense heat conducted through the metal is sufficient to ignite the paint and combust spontaneously. 

On masonry, normal coatings catch fire and act as fuel. Thus, although concrete does not burn, the paint applied to it does, aiding the spread of fire. 

On wood, which catches fire easily, Fyretard does not allow the flames to spread. When subjected to a fire, Fyretard forms a barrier between the flame and the wood. Even after prolonged exposure to a fire, the Fyretard coating is not destroyed and continues to shield the wood substrate thereby reducing the spread of fire.
 
FyrePruffe 

 ‘OBEREG’ from Noble Paints is an intumescent fire-retardant paint that not only retards the spread of fire, it also insulates the substrate from the intense heat of a fire. This coating dries quickly to a flat matt finish having the appearance of a conventional matt finish paint. On contact with fire or excessive heat, the paint puffs up (intumesces), forming a thick, sponge-like cellular foam layer over 100 times thicker than the original paint film. This foam layer insulates the substrate from the heat of the flame, thus retarding flame spread and delaying structural failure. 

Fyrepruffe is a highly specialised paint developed using imported technology and raw materials. It is meant for use on any substrate which must maintain its structural integrity in the event of a fire, such as structural steel, load bearing walls/columns, etc.

 Depending on the substrate dimensions and the thickness of the paint applied, one-hour and two-hour fire ratings can be achieved using Noble’s ‘FyrePruffe’ intumescent coating.
