How to use Zelec ECPs in coatings
The most efficient way to impart surface conductivity is to apply a thin Zelec ECP-based coating on the surface. Zelec ECPs can be used to provide static-dissipative films ranging from translucent to transparent. The degree of transparency depends on several factors, such as the grade of Zelec ECP, resin type, dispersants, dry film thickness and the technique used for dispersion. Zelec ECPs are incorporated using high-speed mixers, media milling and other techniques similar to those applied for pigments. They are compatible with many resins including acrylics, epoxies, urethanes, and polyesters.
How to use Zelec ECPs in polymers
There are two ways to use Zelec ECPs in polymers. If conductivity is required at the surface of the plastic, the powder can be used as a component of a coating or co-extruded film. The electrically conductive functional particles are concentrated in a thin layer at the surface, making this a very efficient way of utilizing the powders. If conductivity is needed throughout the matrix of the plastic, Zelec ECPs can be dispersed into the bulk polymer through extrusion. If conductivity is required in thermoset polymers, Zelec can simply be mixed into the components prior to curing.
Where are Zelec ECPs used
Different Zelec grades are available with tailored properties for applications including clean rooms, dissipative coatings, electronics packaging, static dissipation, textiles, electric components, workstations and many more.
What is ‘surface resistivity’?
The Zelec ECP product range allows manufacturers, including compounders, coating formulators and their customers, to control surface resistivity in their products. Surface resistivity is defined as the ratio of direct current (DC) voltage drop per unit length to the surface current per width.
