Henkel Polybit Rooftite PU10

Characteristics:

• Excellent UV resistance, weatherability & color retention properties
• Excellent resistance to water and vapour
• High solar reflectance
• Moderate thermal insulation

Components:

1. Polyfoam SS-45A: CFC free, polymeric M.D.I based system for producing rigid urethane foam with a nominal core density of 45 kg/m3 by spray process. The system may be applied to substrates where the surface temperature is of the order of 25 - 30°C. Grades, adjusted in reactivity, are available for both cold and hot condition.

2. Polycryl PF: single component, acrylic waterproofing and protective coating especially designed for PU Foam on roof applications.
