dispersed silica acid which expands the surface and facilitates a permanent bond. Applying an primer which is compatible with the specific adhesive is often the most [...] resistance and permanent tack of the surface finishing. Primers are usually applied in a thin film to ensure a proper drying of the coating. Due to the long-lasting [...] some substrates may require an “oxidative pretreatment” before the primer is applied. Adhesion to the substrate and the cohesion of the primer film can be improved
