BD Loops BD-LS Loop Shield Sealant

The BD Loop Sealant (BD-LS) is a professional-grade moisture curing sealant formulated for enclosing, insulating, and protecting inductance loops in gate, door, and parking applications. Unlike standard polyurethane sealants, BD-LS cures quickly, resists bubbling in wet conditions, and remains stable under extreme climates. Each 30 fl. oz. tube comes with a flat sealant tip, allowing installers to complete loop sealing in a single pass with no additional mixing or heating required. Available in Black or Gray, BD-LS offers long-term durability for both interior and exterior use.
