Bond-It WP100 Premium Neutral Cure Oxime Silicone Sealant

(285ml EU3 cartridge in choice of colours)

Flexible, durable sealant for weatherproof, high-movement joints

WP100 is a professional-grade, multipurpose neutral cure silicone designed for high-performance 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. Permanently elastic and with enhanced adhesion to PVCu, WP100 provides durable, consistent sealing across a wide range of substrates and environments.

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 durable performance in correctly designed joints.
