Seal PU is a flexible, single-component polyurethane sealant designed for bonding and sealing across a wide range of materials. It delivers strong adhesion on construction substrates and retains elasticity to absorb vibration and movement, creating waterproof, long-lasting joints. Suitable for interior and exterior work, it resists UV exposure, weather and common chemicals including oils and hydrocarbons. Typical uses include sealing coupling and expansion joints, fixing and waterproofing electrical boxes and light fittings, insulating electrical wires, and bonding tiles, ceramics, stone and other building materials in construction, automotive and fitting applications. It can be painted after cure, contains no silicone and is economical in use, requiring only a thin bead. Supplied in 310 ml cartridges for easy application.
