The original elastic bonding adhesive, Sikaflex ®-252 offers great adhesive strength coupled with elasticity. This combination bonds and seals at the same time, offers excellent gap filling capabilities and compensates for loose tolerances in the building process. Strong enough to sharply reduce or even completely eliminate traditional fastening systems such as welds, rivets, screw and bolts. Excellent Green Strength means reduced clamping time. Bonds to a wide variety of substrates. Some surface prep is generally recommended. Sandable, paintable and NSF approved for incidental food contact.
