DYNASHIELD SP POLYMER ARMOUR
​
Ultra High-Strength Elastomer
Performance
​
Dynashield Polymer is state-of-the-art, high performance, sprayed, plural component pure polyurea elastomer. This system is based on amine-terminated polyether resins, amine chain extenders and MDI prepolymers. It provides a flexible, resilient, tough, monolithic membrane that can be used to for blast and ballistic protection
​
Dynashield Polymer Armour is a specially-designed composite which is applied onto the receiver surface to which it bonds, being built up in layers until the required thickness/protection level is reached.
​
Dynashield Polymer Armour has undergone an extensive trials regime and has been shown to significantly reduce the blast and ballistic threat to vehicles, buildings and other elements by:
-
absorbing
-
dissipating and reflecting blast energy
-
capturing fragments
-
increasing bending strength
-
sealing entry holes
​
This Polymer Armour also has high utility in strengthening buildings vulnerable to earthquake damage and as an extremely hard-wearing protective coating.
​
Features:
-
100% solids. No solvents. No volatile organic compounds (VOCs).
-
Fast set. Handle in two minutes or less. Hydrophobic, therefore unaffected by damp, cool surfaces during application.

Testing
During an explosion, one of the greatest threats is from fragmentation and spalling. In many parts of the world, the most common unreinforced construction technique for the exterior of buildings is to use steel or concrete frames to support the weight of the building and then fill the open areas with stacked brick or concrete blocks to form the walls. When overloaded by air-blast, unreinforced walls typically fracture into pieces that are propelled at high velocity into the interior of the structure causing severe injury and death.
Dynashield Polymer provides an elastic coating that bonds to the wall to form a tough elastic membrane that can dissipate the blast energy and contain the debris. Dynashield Polymer can be sprayed directly onto the interior surface of the wall and cures almost instantly providing a cheap, versatile solution.
Blast testing by TSWG showed that although the exterior face of the concrete block wall was shattered, the interior faces of the blocks remained adhered to the polymer liner. The polymer liner remained intact and effectively contained the fragmentation from the fractured blocks.
