Elegant finishing-Excimer Super Matt Coating

Excimer lamp curing technology

Origin

The IOT company from Germany has created a 172 nanometer UV curing device (EXCIMER) with unique performance, which can be called the “black technology” of UV curing technology.

Working principle

The acrylic ester double bond in the UV coating formula can generate free radicals without the need for a photoinitiator after absorbing 172 nanometer ultraviolet light. At the same time, the penetration depth of 172 nanometer UV is only 100 to 500 nanometers, so only a very thin layer on the surface of the coating is cured. The aggregation and cross-linking of this thin layer will cause shrinkage and form an uneven surface, which will float on the uncured lower liquid layer, achieving a matte surface effect. However, this solidification needs to be carried out in a nitrogen environment, so that the oxygen concentration in the operating environment is below 100ppm. Subsequently, conventional UV or electron beam will be used for complete curing.

This method of extinction is called “physical extinction” because it does not require the use of extinction agents. The polymerization and cross-linking occurring on the surface at 172 nanometers can provide high surface hardness and high coating density.

Other advantages

Anti scratch, self-recovery

Excimer UV skin sensing board uses excimer technology to cure and shrink the paint surface, increase density, create a 4H surface hardness, enhance paint adhesion, and provide superior topcoat bonding strength, enabling it to handle various daily bumps and scratches with ease.

Anti fingerprint, leaving no trace

The excellent hydrophobic structure layer and sliding friction coefficient of the excimer UV skin sensing plate make fingerprint imprints have nowhere to go, no marks when touched, and no marks when pointed.
