Swellable Mastic

ARCAN swelling mastics are available as polyurethane swell mastic and bentonite swell mastic. For the installation of swellable tapes on rough surfaces a swellable mastic is necessary to be used. The swellable material covers the unevenness of the surface and avoids leakages. Mastics come in cartridges and are equivalents to swellable tapes. Swelling pastes are ideal for hard-to-reach areas and pipe penetrations.
