Application surfaces that are challenging to bond to:
- Low energy surfaces such as those that are silicone treated or chemically treated for corrosion resistance, waxed or greasy, or printed polyethylene.
- Rough surfaces where surface contact is likely to be low, such as wood, metal, lacquered finishes, cork, foam, open weave fabrics, embossed finishes, and unglazed pottery.
- Moist or cold surfaces such as those caused by condensation, ice or deep freezing.
- Irregularly shaped surfaces such as glass vials, ampoules, or spirit miniatures where the label is applied to a convex surface of less than 25 mm in diameter.
- Dusty surfaces such as plaster and fiberglass.
- Surfaces which may be extensively exposed to the atmosphere, or submerged in salt or fresh water, or exposed to chemicals (resulting in eventual failure of the adhesive) such as steel drums.
FLEXcon’s Sample Department can provide you with hand samples at no cost to you. If, after testing the samples, you wish to do a short run as part of a more extensive material suitability test, you can order a sample roll of the material. In the long run, material suitability testing can mean the difference between the success and failure of the application, and is more than worth the effort.
