Product Description
USES
CHIL-BYL CP-76 sealant is used to vapor seal the joints of cellular glass and cellular plastic insulations (except polystyrene). It remains flexible and functional through a wide temperature range.
CHIL-BYL CP-76 sealant has good resistance to elevated temperatures, and is recommended as an expansion joint material up to 300ºF.
It is an excellent water seal, vapor seal, and expansion joint material, and is suggested as a joint sealant for metal jacketing systems.
Certain metals such as copper, aluminum, stainless steel and their alloys may be susceptible to corrosion when in contact with some materials. To prevent the possibility of corrosion direct contact between the sealant and these metals should be avoided.
