APPLICATION METHOD: Sink-Not #350 is engineered to be installed by pumping through hoses into the spaces being treated. Equal volumes of base and curing agent are metered from bulk containers such as 55 gallon drums then pumped through separate delivery hoses to an in-line static mixing device. The mixed resins are then fed through a single hose to a discharge nozzle for placement in the void spaces being filled. The mixed resin can be hosed in a stream as far as 10 – 12 feet. As the foam expands during cell creation and expansion it forces into leaks and small holes to form a perfect seal. Small residues of hydrocarbons are incorporated into the foam allowing intimate contact with steel surfaces. The cured resin is an almost perfect “closed cell” system which is highly resistant to saturation by liquids it contacts. The cured resin has been designed to be resistant to attack by all liquid hydrocarbons such as crude oil, gasoline and xylene. The minimum ambient application temperature is 25°F/-4°C. The SINK-NOT 350 components may be heated prior to spraying to reduce their viscosity. Drum temperatures should not exceed 110°F/43°C to avoid excessive internal pressures. Installation equipment exposed to mixed components is simply cleaned with MEK, Acetone or BIO-SOLV solvents. At the conclusion of each project all material lines are flushed with solvent.
