3M Scotch-Weld 5313 Black Sealant 1 x 20 mm, 35 m - 5313 20MM

Preformed Scotch-Seal Mastics 5313. Preformed, self-adhesive, synthetic elastomer mastics that adhere to a number of surfaces, such as plastic, metal, glass, concrete etc. Their strong adhesive properties allow them to affix immediately to the surface, and the mastics will stay in place without being held. They are non-polymerisable and their properties will not change after ageing for long periods in a wide range of environments.
