In developing Granocoat®, Henkel Adheisves Technologies has made a big step forward toward the target of applying pre-coated sheets for automotive bodies.
Granocoat® is an organic coating with long-term corrosion protection for steel strip, ready to use as pre-coated sheet for the automotive industry.
Preferably in combination with a chromate-free pretreatment, Granocoat® is applied on galvanized sheets in the coil coating process. Granocoat® is a functional layer of 2.5- 4.5 µm coating thickness. Sheets coated in this way are protected against corrosion, suitable for spot welding, bondable and conductive, thus enabling subsequent electro-coating.
The application of sheets treated in this way guarantees corrosion protection for inaccessible cavities or flange sections in the automotive construction. Sheets coated with Granocoat® are regarded as the basis for extended corrosion warranties. Henkel’s Granocoat® products have not only many technical advantages, but also several working hygiene/environment, and economic advantages as well.
