1. AWAZEL PU FLEX One component, polyurethane - based, low modulus joint sealant Description AWAZEL PU FLEX is a novel low modulus expansion joint sealant, especially formulated to temperature and humidity climatic conditions. Special Features • No bubbling/swelling upon curing in difficult climatic conditions. • Excellen t Thixotropy • Excellent adhesion on almost any type of surface, with or without the use of special primers. • Excellent extrusion, tooling and storage stability over wide range of climatic conditions. • Execellent chemical resistance, suitable for sealing joint s in swimming pools and chemically treated water. • Low modulus, joint movement accommodation 50%. • Microorganism and fungus resistant. • Excellent heat resistance, suitbale for application where exposure to temperatures >60 o C take place. • Resistance to cold: Th e sealant remains elastic even down to - 40 o C. Uses AWAZEL PU FLEX is recommended for sealing joints in insitu concrete, expansion concreter plates, precast panels, brick and block work, water tanks and swimming pools, metal frames, aluminum windows and p anels, irrigation channels, glass, granite & marble. Method for Application Clean joint thoroughly, and ensure that no oil, grease and wax contaminations, silicone re mains are present.For many applications, primer is not required. In the case Of application on very porous substrates, bond area surfaces thoroughly to avoid the possiblity of air bubbles being blown into the uncures sealant if the substrate temperature rises. Apply backing material such as open cell polyuretha ne or a closed cell pol yethylene backing rod. Although both types of backing rod are recommended care must be taken when using the closed cell polyethylene rod that the outer skin not be punctured as in rising temperature conditions it may cause bubbling. Backing rod applicatio n is important as it ensures that the correct width to depth ratio is achieved provided a firm backing against which the sealant can be tooled off.
