Products should be disposed of according to local, state, and federal laws. When the material has stopped penetrating it will continue to expand against the limits of the confined space and compress within itself,forming a dense, closed cell foam.Įxtreme conditions: For application procedures in extreme temperatures and specific environments or equipment recommendations call the DE NEEF® Technical Service Department.Ĭleaning: Clean all tools and equipment which have been in contact with the resin with DE NEEF® Washing Agent before resin has cured. Injection: During injection the grout will follow the path of least resistance.

Do not leave catalyzed material in the pump longer than 3 hours.Only catalyze as much material as will be used in 1-2 hours.Keep grouting materials cool during storage and pumping.Use the minimum percentage of catalyst necessary for your application.Flush pump with DE NEEF® Washing Agent every 1 to 2 hours.Exceeding the recommended amount of catalyst may adversely affect the reaction and quality of the cured foam. Measure the appropriate amount of Flex Cat PURe (refer to the Reaction Times section of this data sheet for the desired set time) and pour it into the pail. Pour the desired amount of Flex LV PURe into a clean dry pail. Installation Instructions: For detailed installation instructions refer to the DeNeef technical bulletin for your applicatioĬatalyst: Shake catalyst can 2-3 minutes. Warning: DE NEEF® Flex LV PURe must be used with DE NEEF® Flex Cat PURe. Consult the Technical Data Sheets and SDS before using. Sealing moving and non-moving joints in concrete.Sealing leaking cracks in concrete 0.02” and wider.DE NEEF® Flex LV PURe grout expands on contact with water and quickly cures to a tough, flexible foam that is resistant to most organic solvents, mild acids, alkali, petroleum and micro-organisms. DE NEEF® Flex LV PURe is a hydrophobic polyurethane designed to form a flexible gasket when injected into cracks and joints in concrete structures.
