INSTRUCTIONS FOR USE

The Überkoll Ancorante PU/PVC primer is an intermediate product to be used, as stated, on hide, greasy leathers and other difficult substrates before applying the adhesive. To bond high-fat leathers effectively, pay attention to surface preparation. First, remove the grain, the finish or any traces of previous bonding by roughening or sanding (40 grit recommended). If the leather has glossy reflections, finish sanding with a wire brush. The primer to be used and the surfaces involved must be acclimatised before starting the bonding procedure. Stir before use. Immediately after roughening/sanding, spread Überkoll Ancorante PU/PVC and leave to dry; it is important not to let much time pass between roughening and applying the primer, as the leather tends to rebuild its outer layer of fat. Once the primer has dried (20-30 minutes), proceed with final bonding using Überkoll Poliuretano polyurethane adhesive or Überkoll Super D polychloroprene adhesive. To increase the performance of the primer and for optimal final bonding, it can be useful to add 3-5% Überkoll Attivatore to the primer. Store at room temperature in a dry, indoor place, in the original packaging.

Solvent-based product to be used as a primer for preparing surfaces for bonding. Low-viscosity solution recommended as a first coat on hide and compact or oiled leather, vegetable-tanned leather, faux leather and hard-to-bond materials. On difficult substrates this primer creates a base suitable for treatment with our Überkoll Poliuretano adhesive, helping the adhesive anchor to the surfaces to be bonded. Although intended for use with polyurethane adhesives, it has also been shown to improve the adhesion of polychloroprene adhesives on difficult substrates. Generally used in shoe production and repair and in leather goods. Quick drying. Treated materials remain elastic. Free from toluene and chlorinated solvents. Moisture-resistant.
