Abstract
A flexible polyurea and method for making, as well as a kit for making the polyurea. The method and kit include making flexible polyurea by reacting at least a first component comprising at least one of an aliphatic isocyanate or an aromatic isocyanate and a second component comprising a secondary amine together, wherein the ratio of the first component to the second component was in the range from, by volume, 2:1 to 1:2. The flexible polyurea is useful, for example, as a substrate covering (e.g., the interiors of construction, farm, and other vehicles, both military and civilian (including cars, trucks, aircraft, and vessels (e.g., boats, ships, and submarines)).
Claims25
A flexible polyurea comprising a reaction product of at least a first component comprising at least one of an aliphatic isocyanate or an aromatic isocyanate and a second component comprising a secondary amine together, wherein the ratio of the first component to the second component was in the range from, by volume, 2:1 to 1:2.
(canceled)
A method of making flexible polyurea, the method comprising reacting a first component comprising at least one of an aliphatic isocyanate or an aromatic isocyanate and a second component comprising a secondary amine, the first and second components having, at 25° C., a first and second viscosity each greater than 144 Ku.
