The Final Layer
Clearcoat is the final layer of the automotive coating process. The clearcoat paint gives a final gloss and final appearance to the whole car body and plastic parts. The technology is comprised of one or two components, a crosslinked polymer network based on acrylic / polyester / melamine / polyurethane resins. The application is carried out using robots and an electrostatic spray process. Final properties are obtained after an oven cure process at 140°c.
Appearance / Gloss / Effect
A number of effects can be applied to the Clearcoat to deliver differing final appearances.
High surface levelling, optimised refractive index
Tinted CC with transparent pigmentation
Integration of glassflakes particles (NPAC patented)
Levelling monitoring to reduce gloss while keeping a smooth surface
Integration of specific polymeric particles to reduce gloss and create a textured finish (NPAC patented)
Three Main Functions
The Clearcoat’s Polymeric network is specifically designed to ensure high chemical / scratch resistance.
- Covalent bonding
- High crosslinking density
- Balance hardness / flexibility
- Reflow potential
