Static charges on films and plastic surfaces leads to numerous problems. Coating with Clevios™ permits surfaces to be given an antistatic finish. Virtually all types of plastics can be coated with PEDOT, including polycarbonate, polyethylene, polyethylene terephthalate, polyamide, and polypropylene. A surface activation such as a corona treatment should be performed prior to coating in the case of PET and polyolefins to enhance adhesion to the substrate.
Typical applications for Clevios™-based antistatic and static dissipative coatings on plastic surfaces:
- Antistatic trays and blister tapes
- Polarizer Protection films
- Production of photographic films with an antistatic effect
- Plastic electronic component housings and windows
- Clean-room packaging
- Other ESD and dissapative applications
- Depending on the Clevios™ grade used and on the composition of the formulation surface resistivities between 10E3 and 10E9 Ω/square can be achieved.
Coating of glass with Clevios™ formulations
Clevios™ can be used to produce transparent, conductive coatings on glass.
Typical applications for Clevios™
- Based coating on glass:
- Glass apparatus in hazardous areas
By combining Clevios™ with silanes, e.g. tetraethoxysilane, high hardness, scratch resistance, and surface resistance can be obtained. For achieving optimum hardness curing temperatures of about 180°C are required.
Scratch-resistant antistatic coating
Guide formulation CPG 130.6 allows the application of antistatic coatings with good scratch resistance.
Surface resistance: < 10E6 Ohm/sq
Pencil hardness: 9 H
Quantity of Clevios™ P used per m²: approx. 2g (spray application)
Highly conductive coatings
Higher conductivity can be achieved by using guide formulation CPP 105D or the ready to use formulation Clevios™ F 010. The hardness of the coating is however, lower than when using guide formulation CPG 130.6.
Surface resistance: < 10E3 Ohm/sq
Quantity of Clevios™ P used per m2: approx 6 g
The Clevios™ coatings can be either applied by spraying or the spin-coating method.
