Newton 306 SwellMastic is a high-quality, firm, fast-curing, swellable, single-component, polymeric adhesive sealant. The special composition of Newton 306 SwellMastic makes the sealant start to swell when in contact with water (to about 150% of original size). The sealant has high elasticity and high adherence and it develops a strong adhesive tensile strength immediately after application. The first swelling is time delayed which allows Newton 306 SwellMastic to be applied to slightly damp surfaces.
