Arbokol 2150 is a two-part polysulphide sealant, that contains a very high polymer content giving it good chemical resistance to a variety of different materials. It cures to form a hard-wearing yet flexible seal with good adhesion to concrete and many other common building substrates. Use it to seal floor joints in flat roofs, heavily trafficked floor joints, concrete slab constructions, as well as joints in water retaining (non-drinking water) and sewage structures where bio-degradation resistance is required.
