Underwater Magic 290 ML Gray Sealant

Like all great inventions, Underwater Magic was born from a need. The need for a glue that could perform as well under water as above it. And one that would enable us to bring together those two worlds with astonishing results.

Starting with a successful formula used by commercial divers to seal leaks in ships, we teamed with an industry-leading German scientist to push the limits of chemical engineering and created a product that we are proud to call our own. A product that would be aptly named after how it is so often described: Underwater Magic.

It is permanently elastic with good abrasion resistance and good mechanical properties. Temperature resistant from -40C/F degrees to +90C / +194F, for a short time ( 2 to 3 hours) even to +200C / +392F, can fill gaps of up to 40 mm and is allowed in areas close to food.

Underwater Magic comes in a Standard 'Silicone tube size' used with a standard caulcking gun with a filling of 290ml (approx. 9.8 US fl. oz.) or as 600ml bag (approx 20.29 US fl. oz.).
