The 3M™ Fire Barrier™ CP 25WB+ Caulk product is a one-part, intumescent (expands when heated), elastomeric latex caulk. It is used to seal construction openings, blank openings and penetrating items such as cables and pipe, against the passage of flame, smoke and water. It is also used in conjunction with 3M™ Brand FS-195+ Wrap/Strip and CS-195+ Composite Sheet. The CP 25WB+ Caulk is packaged in 10.1-ounce cartridges, 20-ounce sausage packs, 27-ounce cartridges, 2-gallon pails and 5-gallon pails. The caulk may also be packed into 55-gallon drums for packaging into cartridges and sausage packs.
