CP-9 Ak-Cryl® Coating

Description:

CP-9 Ak-Cryl® Coating is an economical, polymeric, water based weather barrier, breather type mastic. CP-9 dries to a tough flexible film that protects thermal insulation from the ravages of weather by preventing water, rain, snow, sleet, spillage, wash water, etc., from entering into the system. In addition, CP-9 provides protection from mechanical damage created by external forces such as impact abrasion as well as the internal forces of thermal expansion, contraction, or vibration. Using CP-9 can also protect the insulation from chemical attack of acids, alkalis and solvents. CP-9 is fire resistant and U.V. stable.
