Tinuvin® XT 847 FF

Tinuvin® XT 847 FF by BASF is hindered amine derivative. It is a novel NOR-HALS based high performance light stabilizer system that represents a significant advancement in light stabilization of polyolefins, especially for flexible TPO compositions used in membrane applications.

• In addition to the superior weatherability, it imparts thermal stability, surface protection to TPO roofing membranes while providing lower interaction with system components and environmental contaminants.
• Enhances the durability of TPO membranes by retaining its surface and physical properties.
• The main advantage is that it significantly extends the life of the membrane with lower concentrations than other light stabilization systems.
• It is highly recommended for building and construction TPO exterior roofing membrane and geomembrane applications.
• Tinuvin® XT 847 FF usage level ranges from 0.05 to 0.5%, depending on the substrate and the performance requirements of the final application.
