Abstract
A coated sheet metal strip includes a rolled sheet metal strip having a first flat side and a second flat side. A first layer over the first flat side includes a carrier layer. The carrier layer contains a reaction accelerator for an adhesive and stores the reaction accelerator on a physical basis. A second layer, including the adhesive, is applied over the second flat side. The second layer is free of the reaction accelerator or any reaction accelerator.
Claims19
A coated sheet metal strip, comprising:
- a rolled sheet metal strip having a first flat side and a second flat side;
- a first layer over the first flat side, wherein the first layer includes a carrier layer, the carrier layer applied directly to the sheet metal strip and containing a reaction accelerator embedded in the carrier layer for an adhesive and stores the reaction accelerator on a physical basis, wherein a ratio in volume of carrier layer material of the carrier layer to the reaction accelerator is between 1/1 and 3/1;
- and
- a second layer over the second flat side and including the adhesive, wherein the second layer is free of the reaction accelerator or any reaction accelerator.
