Henkel Polybit Polyproof Ultra FB Pre Applied System

Traduzido pelo Google,

Polyproof Ultra Plus é uma membrana impermeabilizante à base de HDPE totalmente aderida, pré-aplicada e de alto desempenho, com acabamento granular fino inorgânico reativo. A membrana foi projetada para formar uma ligação química e mecânica com o concreto recém-derramado, tornando-se efetivamente parte integrante da estrutura.

Os campos de aplicação incluem estruturas subterrâneas de concreto, como:

- Porões

- Abaixo das jangadas

- Paredes de contenção

- Aplicações infraestruturais (túneis e pontes)

Especificação

Characteristics:
- Loosely laid membrane that remains independent of structural movements and settlements
- Cold-applied, easy, and quick to install, no priming required
- Chemical bond of pressure sensitive adhesive with concrete
- Mechanical adhesion through granular sand finish
- Effectively prevents lateral water migration
- Provides a water and moisture barrier
- Allows for immediate foot traffic on site
- Temporarily UV resistant during application and steel works (45 days during hot climate)
- Excellent resistance to chemical acids, alkalis, salts, and other corrosive materials
- White solar-reflective surface
Components:
1. Polyproof Ultra Plus: Fully-bonded, sand coated, pressure sensitive HDPE pre-applied, single layer loosely laid membrane for substructural waterproofing application.
2. Polyproof Ultra Plus TS: single-sided, self-adhesive tape with sanded finish. The carrier is coated with a pressure sensitive adhesive with excellent adhesion to the Polyproof Ultra Plus membrane.
3. Polyproof Ultra TSD: Polyproof Ultra TSD is a double-sided, self-adhesive HDPE tape. The carrier is coated with a pressure sensitive adhesive on both sides with excellent adhesion to the Polyproof Ultra Plus membrane.
4. Polyproof EPU: cold-applied, elastomeric, two-component hybrid polyurethane-based sealing compound, designed for detailing and repairing the Polyproof Ultra FB system and for filling imperfections on concrete surfaces.
5. Polyseal 1PU: Highly flexible, non-staining paintable one part polyurethane joint sealant with excellent recovery.
