Installation Instructions for CP 672 FC
Notice: Before handling, read Material Safety Data Sheet and product label for safe usage and health information. Instructions below are general guidelines; always refer to the applicable drawing in the UL Fire Resistance Directory or Hilti Firestop Systems Guide for complete installation information.
- Opening: Clean the opening. Surfaces to which CP 672 FC will be applied should be cleaned of loose debris, dirt, oil, wax, and grease. The surface should be moisture and frost-free.
- Install curtain wall insulation and other system components if required.
- Application of firestop spray: Mineral wool packing: Install the prescribed back-filling material type and depth to obtain the desired rating.
- Mixing of CP 672 FC: Take off the lid. Remove and open the small plastic container, and empty into the pail of white spray (remove plastic cover first). Mix with a mixing paddle for 3 minutes until the spray turns gray.
- Application of firestop spray: Apply CP 672 FC to the required depth to obtain the desired rating. Ensure CP 672 FC contacts all surfaces and overlaps beyond all surrounding surfaces (Refer to UL System). Hilti recommends using Titan 600 (for application temperatures above 50°F) or 1100 Sprayers. CP 672 FC may also be brushed on with a paint brush. Contact Hilti Technical Support for more information.
- Curing time: Allow 7.5 hours (at 77°F) for CP 672 FC to provide resistance to rain. Full cure in 3-5 days for typical application thickness.
- Identification: For maintenance reasons, all CP 672 FC applications can be permanently marked with an identification plate fastened in a visible position next to the seal.
Not for use:
- In areas immersed in water
- On hot surfaces (above 176°F)
Storage:
Store only in the original packaging at temperatures 40°F to 77°F (5°C to 25°C). Observe expiration date on package.
