What if I put 3 ZuluShield layers together, 1 on top of another–will that reduce blast effect to 1/3 compared to using just 1 layer?
With explosive dusts and gases, the quenching reaction happens within a centimeter or so of the ZuluShield surface, so making it thicker makes no difference (surface coverage is very important, in contrast). With detonating solid explosives, thickness is important only for intense blasts, such as large charges in containers, with dense-packed munitions, or large anti-vehicle ground mines. For very intense blasts, a layer of extinguishing chemicals is much more helpful instead of more of the bead-filled ZuluShield layers.
