300ml Acetoxy Silicone – Black

Our 300ml Acetoxy Silicone Sealant is a versatile, trade-grade solution for creating permanent, flexible, and waterproof seals. Known for its “vinegar-like” scent during curing, acetoxy silicone is prized for its rapid skinning and curing time, making it the go-to choice for professionals and DIYers who need a reliable seal in a variety of environments. This sealant is specifically formulated to provide excellent adhesion to non-porous surfaces such as glass, ceramics, aluminium, and many plastics. Its high-flexibility properties allow the seal to absorb joint movement without cracking or peeling, ensuring long-term durability. Whether you are sealing around window frames, capping glazing, or performing general household repairs, this silicone provides a professional, high-gloss finish that stands the test of time. Because aesthetics matter, we stock this sealant in four essential colours: Black: Perfect for dark window frames, automotive repairs, or decorative accents. White: The industry standard for sanitary-ware, kitchens, and bright PVC frames. Brown: Ideal for mahogany or wood-effect uPVC windows and doors. Clear: Transitions seamlessly between different materials for a “barely-there” finish. Product Features: All-Weather Performance: UV-resistant and waterproof, making it suitable for both internal and external use. Fast Curing: Quick skin-over time speeds up project completion. Permanently Flexible: Accommodates structural movement and vibrations without losing its seal. Multi-Colour Range: Available in Black, White, Brown, and Clear to match your specific surfaces. Easy Application: Fits all standard 300ml caulking guns for a smooth, controlled bead.
