KANAT PAINTS & COATINGS and OCSiAl have jointly developed conductive acrylic primers with graphene nanotubes for polypropylene and SMC plastic parts. This makes it possible to apply base-coat and other coating systems to automotive exterior plastic parts via a cost-effective method: electrostatic application.
Efficient and Economic Base-coat Application
“
Our product line is flexible and adapts to match the request of each specific customer. What is distinctive with the graphene nanotube solutions provided by OCSiAl is their unprecedently low working threshold – the required concentration starts at only 0.01% of nanotubes. This is crucial for applications where the color and durability of a final product are of great importance,” explained Mr. İlhan Demiral, technical sales & business development manager from Hayim Pinhas A.Ş., a distributor of
graphene nanotube solutions in Turkey.
“
The new primer demonstrates improved quality in comparison to alternatives with other conductive additives, such as carbon black. High-adhesion gives the ability to assemble SMC parts coated with primer onto the metal body at the beginning of the painting process.”
“
In addition, single wall carbon nanotubes make it possible to produce light-grey primers with a high L-value (> 70%) and high transfer efficiency. This leads to reduced base-coat consumption in comparison with black primers and potential cost reductions,” said Mr. Alper Kades, R&D director from KANAT PAINTS & COATINGS.
Currently, advanced nanotube primers are in the process of receiving practical approval from several leading OEM manufacturers.
