Seam sealing was already performed manually successfully for preventing perforation corrosion in the 1980s. [1] Today used in the OEM automotive industry primarily for the purpose of seals against air leaks and to waterproof sheetmetal overlaps that occur in the assembly of a vehicle. Such overlaps are typically decorative rather than ...
Again, refined tar-based sealer offers the best wear characteristics (typically 3–5 years) while asphalt-based sealer may last 1–3 years. Petroleum-based sealer falls between refined tar and asphalt. There are concerns about pavement sealer polluting the environment after it is abraded from the surface of the pavement.
These days, automotive paints come in liquid form, spray form, and powder forms:- Liquid: Usually polyurethane paints. Compressor is needed to apply.

Sealants can be categorized in accordance with varying criteria, e. g. in accordance with the reactivity of the product in the ready-to-use condition or on the basis of its mechanical behavior after installation ...
The seam is made by mechanically overlapping the two layers to form a hook. Different parameters of the hook are measured and monitored to check the integrity of the seam under different conditions. The shape of the double seam is determined by the shape of the seamer roll profile and the relative position. During the can seaming process, the ...
Induction sealing also offers advantages when sealing to glass: Using a conduction sealer to seal a simple foil structure to glass gives no tolerance or compressibility to allow for any irregularity in the glass surface finish. With an induction sealer, the contact face can be of a compressible material, ensuring a perfect bond each time.
