SPECIAL COATING

Required feature for electric
partsmanufacturing equipments
(SEMI, LCD, LED, Solar, etc.)

  • Large-scaled equipment and parts

    - Cost increased for large-scaled parts
    - Cost increased for using highfunctional materials

  • High functional

    - Required control of nano-sizeparticle.
    - Required stability of thermal resistance and conduction
    - Required electric and chemical stability
    - Required high purity for minimum contamination

  • Improvement for equipment lifetime

    - Improved equipment lifetime
    - Required corrosion, abrasion, plasma resistance
    - Required stability in high temperature, electric, chemical environment

Core coating technology

Coating technology is divided according to coating technique and properties, and it is developing a differentiated coating technology only for Dieptec to respond to changes in nanotechnology.

- PLASMA COATING MACHINE enables uniform COATING THICKNESS implementation regardless of part type
- RA formation on the base material before coating to improve adhesion between the part base and the COATING POWER
