UV-Schutzlacke für CD-RW
Key technologies for CD-RW
• Excellent durability
• Excellent adhesion to Al
• Higher pencil hardness (if hard coat layer is required)
• Cost performance
SD-374 is designed for CD-RW to achieve those key technologies.
Some customers require 'hard coating' on Polycarbonate. SD-715 is our UV curable laquer for hard coating on CD-RW and DVD+/-RW.
