Bond-It WP100 Premium Neutral Cure Silicone Sealant (285ml EU3 cartridge in choice of colour and pack size) Flexible, durable sealant for weatherproof, high-movement joints WP100 is a professional-grade, single-component, moisture-curing neutral cure silicone for perimeter sealing and flexible jointing in construction. It is suitable for external door and window frames, infill panels, and joints between dissimilar materials where movement is expected. With permanently elastic performance and enhanced adhesion to PVCu, WP100 provides durable, consistent sealing across a range of substrates. Designed for dynamic jointing, the sealant offers fast skin formation, controlled cure rates, and movement accommodation of up to 25% for internal and external use. It conforms to EN 15651-1, -2 and -3 (F EXT-INT, G, XS1) and incorporates fungicide for mould resistance. Strong elastic recovery, good tensile strength, and resistance to UV exposure, weathering, and temperature extremes support long-term performance in correctly designed joints.
