Conductive automotive primers: How to optimize formulation with TUBALL™ MATRIX

Today, more and more automotive parts are made of polymers. For them to be electrostatically painted in the way that metal body structures are, they must first be coated with electrically conductive primers.
Ordinarily, conductivity in primers is achieved using carbon black additives or conductive pigments (such as TiO2 or conductive mica).
OCSiAl proposes a new solution in conductivity - additives based on single wall carbon nanotubes, TUBALL, that provide significant benefits in comparison with standard conductive agents.
In this video we will tell you how to create conductive, light-colored primers with graphene nanotubes in the most effective way.

The solutions and answers you will find in this video:
• How to create conductive, light-colored primers with TUBALL graphene nanotubes in the most effective way
• How to optimize the formulation to create conductive, light-colored primers with graphene nanotubes
• How to prevent instability, inappropriate dispersion and agglomerations in conductive primers by building an optimal formulation
• How to avoid a decrease in conductivity by selecting the optimal components for your formulation
• How to find the most suitable conductive agent and optimize the formulation accordingly both for acrylic solvent-based or water-based primers
