An innovative spray-on armor protection
system is currently being evaluated for potential use in Iraq. The
system, developed by a British company uses DynaShield SPI blast and
ballistic resistant polymer, which can be sprayed on existing
surfaces (such as vehicle's body parts). When the polymer dries, it
provides additional protection, at lower weight compared to
comparable protection provided by add-on steel plates.
A 3/4 inch layer of DynaShield SPI
demonstrated ballistic protection similar to a 3/8 inch thick steel
plate (RHA). A 0.2" steel plate covered with 3/4" DynaShield SPI
stopped 0.50 Cal bullet at 2736 fps, and multiple shots of 7.62x54mm
at 2741 ft/sec. DynaShield SPI can be applied in the field to
existing surfaces and structures, without modifications or redesign.
It can also be applied to protect shelters or fortifications.
DynaShield SPI also provides a reactive
sealant; protecting forward positioned fuel storages. The polymer is
sprayed on regular barrels, to protect from leakage of hazardous or
flammable liquids. The spray-on polymer seals the barrel after it is
penetrated by multiple bullet hits and prevents further leakage from
the perforated barrel.
