To fully understand the revolutionary properties of BARRICADE, it helps to examine the protective gel coating on a microscopic basis. As BARRICADE and water are sprayed onto an exposed surface, millions of tiny bubblets© are stacked one on top of another.
This stacking behavior is similar to that of AFFF or Class A foams, except that BARRICADE bubblets are water filled, whereas foam bubbles are only air filled. These unique water filled bubblets dramatically enhance the thermal protective qualities of BARRICADE over that of standard foam products. In order for the heat of the fire to penetrate the protected surface, it must burn off each layer of the BARRICADE bubblets coating. Each layer holds the heat away from the next layer of bubblets beneath. The polymer shell of each bubblets and their stacking behavior significantly impede water evaporation. As a result, BARRICADE can provide thermal protection from fire for extended periods even at 3500° Fahrenheit.
