CFL PURe is a hydrophobic polyurethane designed for void filling and barrier wall grouting. Depending on the temperature and amount of accelerator (Flex Cat PURe) used, the grout quickly cures to a tough closed cell polyurethane foam that has some flexibility to accommodate differential movement. CFL PURe is resistant to most organic solvents, mild acids, alkali, petroleum and micro-organisms.
- Sealing spaces with differential movement
- Filling voids
- Barrier Wall Grouting
- Free Foam Expansion up to 20 times
- Contains no volatile solvents
- Single Component
- Will not dilute in water
- Controlled reaction time
- Tough foam with flexibility
Packaging & Handling
5 gallon metal pail
50 gallon metal drum
Flex Cat PURe:
25 fl. oz. in 1 qt. metal cans
CFL PURe is sealed under dry nitrogen because it is sensitive to moisture, and should be stored in original containers in a dry area. Storage temperature must be between 40°F and 90°F. Once the packaging has been opened, the useful life of the material is greatly reduced and should be used as soon as possible. Shelf life: 2 years.

Warning: CFL PURe must be used with Flex Cat PURe. Consult the Technical Data Sheets and SDS before using.
Installation Instructions: For detailed installation instructions refer to the DeNeef technical bulletin for your application.
Catalyst: Shake catalyst can 2-3 minutes. Pour the desired amount of CFL PURe into a clean dry pail. 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. Stir until adequately mixed. Exceeding the recommended amount of catalyst may adversely affect the reaction and quality of the cured foam.
Injection: During injection the grout will follow the path of least resistance. 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.
Extreme conditions: For application procedures in extreme temperatures and specific environments or equipment recommendations call the DeNeef Technical Service Department.
Cleaning: Clean all tools and equipment which have been in contact with the resin with DeNeef Washing Agent before resin has cured. Products should be disposed of according to local, state, and federal laws.

Health and Safety
Always use protective clothing, gloves and goggles consistent with OSHA regulations. Avoid eye and skin contact. Do not ingest. Refer to SDS. For emergencies, call CHEMTREC 1-800-424-9300.
CFL PURe must be used with Flex Cat PURe.
Low temperatures will significantly affect viscosity. If site temperatures are extremely low, heat bands or heated water baths may be used on the pails before and during installation to maintain the product’s temperature. Avoid splashing water into open containers, as the material is water activated. Avoid exceeding 90⁰F when warming.
CAUTION: pH NOTICE. Water used to activate PURe Grouts must be in the pH range of 3-10 for optimum foam quality.
