They can form an instant seal against water, air or dust, and remain permanently soft. They are ideal for filling gaps and sealing joints such as those on bolt-on duct flanges and circular ducts in HVAC systems, air-conditioner casings, roofing and cladding systems, caravan roofs and panels, automotive windscreen and tail lights, glass and metal.
