Body and sheet metal
Seam sealers for body panels, doors and container joints — sandable, paintable, four colours.
Choosing one
KA540 is a sealer, not a structural adhesive. The 600% elongation and 2.5 MPa are chosen so the bead follows a flexing panel and still sands and takes paint. Where the OEM drawing calls for a panel bond, the product class is different and the bond line is 0.2–0.5 mm, so do not substitute.
Send the seam type, substrate and whether it will be painted, and we will confirm sealer or structural. ryan@pu-karmind.net
