Shamu's goal is to help build a more secure environment that reduces structural damage and injury or even death caused by targeted attacks with explosives.
Looking at the anatomy of an explosion, most devastation occurs from the massive pressure that blows apart a structure. By forming a strong “skin" that holds the structure together and reduces fragmentation, the blast is less likely to cause severe damage.
Introduction
Qtech-420 is invented by Qingdao Shamu Advanced Material Co.,Ltd. and Institute of Functional Material in Qingdao University of Technology and it performance has been the top of in China and leading worldwide in its similar category polyurea.
Qtech-420 Super Impact-resisting Polyurea Material is the state of the art 100% solids, flexible, spray-applied, two components, fast set, and aromatic pure polyurea elastomer. The system consists of component A, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyether-amines, amine extenders and other additives. This ultra high-strength, high-elongation polyurea can be sprayed onto virtually any surface configuration and to any thickness. It is excellent for interior and exterior applications. Qtech-420 is used by itself or in combination with other materials to produce armored under pan anti-collision and friction coatings, liners, wearing courses, and resilient surface. Qtech-420 can produce an extremely tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate. Qtech-420 is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.
Applications
Qtech-420 Super Impact-resisting Polyurea Material is the state of the 100% solid content，has extreme reacting speed and excellent mechanical performance. It can be sprayed for several 10mm thickness, non-voc and environmental-friendly. It has uniform and flat disappearance with good impact resistance, anti-abrasive, anti-corrosion and waterproof and can be widely used for the protection in military device, blast mitigation for building and field of explosion resistance.
