  • the connecting means 12 consists of an applied primer, So from a so-called primer layer.
  • Adhesive primer is the name for media that promote adhesion Painting or coating. They are extremely fluid and therefore sprayable and brushable. This results in very thin layers (0.005 to 0.008 mm). Their liability-mediating effect is based on the chemical reaction of their components with each other and with the respective Surfaces made of metal or plastic, for example, which is why The term "reaction primer” is common. Adhesive primers result usually a glazing layer. Primers are generally used as primers designated with an adhesive effect. They are also sometimes called Reaction primer referred to and assigned to the primers.
