fako® Sealing putty 3765, made of butylrubber, has been developed as a supplement to the fako® Sealing strip 3714, for most sealing purposes where absolute resistance to ageing is required and for which an intermediate layer of 0.8 mm to 1 mm has to be used. In combination with the Sealing strip 3714 most desired thickness’s can be obtained for seals. The putty does not become hard but remains plastic and elastic. To fulfil its requirements the putty has not only to be elastic but also plastic so that, when pressed, it will penetrate into any gaps and remain, thus forming a complete seal. Technically this is only possible through a combination of two basic materials with the same chemical composition but with different molecular weights. With two components the above requirement is met for both sufficient penetration depth and stability of the kit at the same time. By simple filling with a putty knife, you can obtain a min. thickness of approx. 0.2 to 0.3 mm. Priming is not required.
