A sealant compsn. comprises a non cationic o/w emulsion of bitumen and rubber, contng. a flow controlling agent, a filler and/or a base. The rubber may be present in latex form or dissolved in the bitumen and the latter pref. has a penetration value of 15-450 down at 25 degrees C...
The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide, particulate, synthetic amorphous silica and plant-derived organic agricultural seed flour, together with a non-black colored colorant. The butyl rubber-based sealant precursor layer is build into...
