Tufflon-P90FR is a flame-retardant polyurea, suitable for applications such as flammable liquid storage bunds or explosives storage areas where there is a risk of open flame or spark. This is a two-component, 100% solids, spray-applied, elastomeric protective coating that is free of solvents or partially soluble diluents such as Propylene Carbonate.

With all the characteristics of Tufflon-P90, such as high hardness, permanent elasticity, corrosion/abrasion and chemical resistance, Tufflon-P90FR has the added benefit of being self-extinguishing.
This is a two-component, 100% solids, spray-applied, elastomeric protective coating that is free of solvents or partially soluble diluents such as Propylene Carbonate.
Specialised, high-pressure, heated, plural proportioning equipment, fitted with an airless, impingement mix, spray gun is required to apply this product.
The flame retardancy is evaluated by several methods and standards. Measuring the time that material will propagate a fire is one of the more commonly used methods (UL-94 & AS ISO 9239.1). A piece of Tufflon-P90FR is exposed to an LPG flame and ignition is observed. The P90FR is removed from the flame and the time taken for it to self-extinguish is recorded. Once the flame has extinguished, the test is repeated on an area previously exposed to the flame.

Introduction: The High Cost of Crumbling Joints In a busy warehouse or industrial facility, the floor is the foundation of your operations. Yet, the weakest point is often the most overlooked: the control and construction joints designed to manage concrete movement. Every time a hard-wheeled forklift or heavy pallet jack crosses a joint, the delicate […]
