Henkel Polybit Rooftite PU10

Traduzido pelo Google,

Rooftite PU10 é um sistema de cobertura resistente a vazamentos de longa duração, com proteção térmica eficiente para as estruturas metálicas do telhado. É composto por uma espessa camada de espuma de poliuretano e revestimento acrílico à base de intempéries e impermeabilização - que é resistente aos raios UV, outros agentes de intempéries e totalmente aderido à superfície de espuma de PU - representando a opção mais segura para telhados metálicos expostos permanentes e temporários.

Campos de aplicação:

– telhados industriais

– telhados metálicos

Especificação

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.
