NanoFlame-Serie - New Surface Pretreatment Devices

The new flame pretreatment devices of the NanoFlame serie are basing on the principle of flame-pyrolytic surface silicating. The flame pretreatment devices generate a very thin (5 - 40 nm) but very dense silicate layer by flame- pyrolytic deposition of an organosilicone compound. This silicate layer produces very high suface energy and has an excellent adhesion to

• metals
• glass
• ceramic
• polymeric materials

The nano-porous surface structure of this layer delivers a better mechanical anchoring of the following polymer as well as an excellent chemical bonding of organic components to the silicate. The silicate layer remains reactive for at least one week after the flame-pyrolytic pretreatment.
The short exposure time of the flame keeps the temperature on the substrate fairly low. This makes it possible to treat even very thin plastic foils.
In combination with Polytec PT's HP-series of silane-based adhesion promoters and hydrophobic adhesives, this silicate layer provides the base for long term water and solvent resistant adhesive bondings and coatings.
