Abstract
A multi-component, chemically-curing, non-cellular, polymeric composition includes a resin component having a resin density, a reactive component having a reactive component density, and an aggregate component having a spherical shape, a diameter of about 0.1 mm to about 10 mm and an aggregate density. The density of the aggregate component is within 2 lbs/gallon of the density of at least one of the resin component or the reactive component.
Claims20
A multi-component, chemically-curing, non-cellular, polymeric composition comprising
- a resin component having a resin density
- a reactive component having a reactive component density,
- an aggregate component having a spherical shape, a diameter of about 0.1 mm to about 10 mm an an aggregate density, wherein the density of the aggregate component is within 2 lbs/gallon of the density of at leaset one of the resin component or the reactive component,
- wherein the resin component comprises an epoxy resin, a polyol resin, a polyurethane forming resin, or a polyurea resin.
(canceled)
A method of continuously dispensing a multi-component, chemically-curing, non-cellular polymeric composition to a work area, the method comprising
- providing a reactive component, a resin component, and an aggregate component,
- combining the aggregate component with at least one of the reactive component or the resin component to form a filled reference component,
- delivering a flowing volume of the filled reference component and a flowing volume of the component that was not combined with the aggregate to a mixing device at a fixed volume ratio of the volume of the filled reference component to the volume of the component that was not combined with the aggregate,
- mixing the flowing volume of the filled reference component with the flowing volume of the non-combined component at the fixed volume ratio in the mixing device to form the multi-component, chemically-curing, non-cellular polymeric composition, and
- dispensing a flowing volume of the polymeric composition to the work area,
- wherein the aggregate component has an aggregate density that is within 2 lbs/gallon of a density of at least one of the resin component or the reactive component and wherein the filled reference component is formed by combining the aggregate component with the at least one component having a density within 2 lbs/gallon of the aggregate density.
