The use of new conductive gel coats with graphite nanotubes as a protective layer on the surface of fiber reinforced plastics (FRPs) enables engineers and designers to apply special surfaces and uniform coatings to the final parts regardless of the parts being conductive Still non-conductive. With the advantages of easy processing, flexible coloring, chemical resistance and zero emission, the powder coating on the gel coat provides a viable liquid coating alternative for FRP parts used in automobiles, shipbuilding, aviation and even sanitary facilities.
The value of FRP lies in its strength and the freedom it can bring to designers, but it is often limited by the type of coating applied. The latest tests for the application of conductive gel coats prove the possibility of using powder coatings. This is a new development in thermoset composite coating technology.
"The obvious benefits of powder coating include: no release of volatile organic compounds, no solvent, good protection and decorative properties, it mainly uses electrostatic coating, and is often used for coating metal parts. It can be used in FRP This kind of insulator sprayed with powder coating has brought great benefits, such as simpler processing and wider coloring ability, including comprehensive effects, excellent performance and chemical resistance." The relevant personnel said.
This new series of conductive gel coats is derived from the knowledge and experience gained by BüFA Composite Systems using graphite nanotubes to develop polyester resin solutions.
"TUBALL graphite nanotubes are the key to combining permanent resistivity and stable resistivity. These characteristics are already available in the gel coat series. The latest gel coat type is customized for the application of powder coatings. We are sure. , It has opened up new promising application areas." Relevant personnel said.
Conductive thermosetting resins, such as polyester, epoxy resin, vinyl ester and other materials modified with graphite nanotubes, have been widely used in pipelines and storage tanks, ventilation systems, printing drums, control boxes, and floor coatings in industrial production workshops And in the mold field, high gloss, uniform surface, dustproof effect, safer and more convenient demolding and shorter processing cycle are the advantages of conductive mold gel coats often mentioned by mold manufacturers.
