Description
PFC Corofil C700 Fire Rated and Acoustic Foam is a one part, moisture curing polyurethane foam. The foam is supplied in 700ml cans and is available in either hand held or gun grade cans.
Joints should first be clean, dry and free from dust, grease or any other loose material. The surfaces should be lightly moistened to ensure good adhesion. The can must be shaken vigorously for approximately 30 seconds and then the nozzle screwed onto the valve. The can is then inverted and the trigger depressed to extrude the foam.
Fill the joint to approximately half it's width allowing the foam to expand. With larger joints it may be necessary to allow one layer to cure before foaming another layer on top.
The foam is tack free in approximately 20 minutes and fully cured within 2 to 4 hours.
Do not cut back the face of the foam once it has cured, as this will seriously reduce the fire resisting characteristics.
PFC Corofil Firestop and Acoustic Foam C700 can be identified from other builders' foam by its pink colour in the cured state.
