Bostik Seal N Flex 300ml polyurethane sealant is a class ‘A’ one component polyurethane gun grade construction sealant.  It is a low modulus and when cured it will form a tough, flexible seal capable of cyclic expansion and compression movement of 50% (± 25%) of the original joint width.  Seal N Flex is virtually unaffected by normal weathering conditions such as rain, sunlight, snow, ultra-violet radiation and pollution.  Its excellent weatherability enables it to retain it s original properties after years of exposure.
