Antistatic Coatings
An electrically conductive coating is designed to reduce or prohibit a static-electrical charge and its effects. Clevios™ antistatic, static dissipative, and conductive coatings of IC packaging trays prevents damage to sensitive electronic components from electrostatic discharge (ESD) through its coating applications. Clevios™ is available as aqueous dispersions, aqueous formulations, and solvent-based.
Static charges can lead to various problems and frequently occur on plastic surfaces. Heraeus Epurio’s Clevios™ coating has been designed to produce surfaces with an antistatic, static dissipative, or conductive finish with precisely tunable sheet resistances (SR) in the range of 10E4 – 10E10 Ohm/sq.
ICs, display or sensor module packaging trays coated in Clevios™ are protected from ESD damage of their sensitive electronic components. The coating also keeps away dust and other particles. Moreover, Clevios™ coatings are clear and transparent, allowing for visual inspection of parts and components in the packaging trays.
Clevios™ can also be used in non-electronics applications, such as cleanroom windows, instrument housings, specialty papers, photographic film, glass coating, construction and building materials, release coatings, labels and so on. In explosion-proof environments, possible static charges occurring on parts or equipment can have disastrous consequences. Clevios™ helps to prevent the build-up of static charges and increase safety.
Many plastics can be coated with Clevios™, including polycarbonate (PC), polyethylene (PE), polyethylene terephthalate (PET), polyamide (PA), and polypropylene (PP). We recommend surface activation by corona or plasma treatment prior to coating as it enhances adhesion to the substrate. Primer-coated substrates can also be a good choice.
Customers can choose from one of our ready-to-use Clevios™ F formulations that can be directly applied, or an individual formulation prepared from Clevios™ P T2, an aqueous PEDOT:PSS dispersion raw material.
