HB50
synthetic compound, with long-term flexibility, in an unformed state which, when applied to a joint, seals it by adhering to appropriate surfaces within the joint, preventing the passage of dust, moisture and gases
It is used to provide a substantially weatherproof barrier in external applications. Typical sealant materials are silicones or silicone-based materials, polysulphides and polyurethanes.
