Abstract
Composite coating (10) improves the resistance to blast or seismic forces of a structure (100), such as wall (101). Coating (10) includes a first layer (20) of elastomeric polyurethane in contact with and adhering to wall (101), a second layer (30) of elastomeric polyurethane in contact with and adhering to first layer (20), and a layer of textile (40) embedded between first layer (20) and second layer (30).
Claims8
In combination:
- a structure that includes a wall having a surface;
- and a composite coating adhering to said surface of said wall for increasing the resistance to explosion forces of said structure;
- comprising:
- a first layer comprising an elastomer in intimate contact with and adhering permanently to said surface of said wall;
- a second layer comprising an elastomer in intimate contact with and adhering permanently to said first layer;
- and
- textile embedded between said first and second layers, wherein said elastomer is the product of a fluid precursor that cures in ambient conditions to form said elastomer, and wherein said composite coating functions to increase the apparent ductility and elongation of the wall when sudden lateral or explosive force is applied to the structure, wherein said fluid precursor is a two-component formulation the reacts upon mixing to become an elastomer.
