Product Details
Waterproof Silicone Sealant 300ml – 950 KPA Bond, Flexible & Weather-Resistant
This structural silicone sealant provides a strong, waterproof bond for a wide variety of surfaces – including glass, concrete, metal, brick, and tile. With an adhesive strength of 950 KPA, it reliably fills gaps, holes, and cracks, and holds up under significant stress and movement without tearing or failing.
The formula stays flexible after curing and adapts to vibration, thermal expansion, and structural movement – making it equally suited for indoor repairs and outdoor construction work. It cures quickly and leaves a clean, glossy finish.
Suitable for windows, doors, aquariums, curtain walls, sunroofs, pipe repairs, and general caulking work. The neutral-cure formula has a mild, non-pungent odor and is suitable for use in enclosed spaces.
