In the world of graphic applications, proper adhesion can be the difference between a satisfied client and the costs of a reprint and reinstallation. Better understanding of the surface to which you are installing graphics and the adhesive options available for the graphics are crucial to assure satisfaction in the overall application and avoid costly re-engineering. Adhesion failure regarding graphic applications may take many forms but most often pertains to product mismatch or improper surface preparation.
Undesired adhesion quality is most often a result of surface tension regarding the application surface. Plastics and textured surfaces carry a low surface tension rating while standard painted metals and glass have a high surface tension. As you address you graphic needs with a decal supplier, application surface should be discussed to best determine the most suitable adhesive component. Graphic film suppliers have access to adhesive options with specific design for low surface tension. There are also many custom options available for other specific surface types. Engineering the construction of the graphics to the specific surface of an application is vital for long-term industrial graphics.
Delamination can also occur when the film adhesive is not fully activated. This may be due to contaminants where the adhesive is applied and little bonding occurs. To help the installers address this problem and ensure reliable results with graphic films, many film suppliers have developed application instructions that include recommended parameters for surface preparation and installation environment. By following these types of instructions and being aware of decal storage and applications environment criteria, graphic installers can quickly and easily obtain good adhesion to most standard flat surfaces.
