UV-Kleber für DVD

Key technologies for DVD-ROM

• Cure at over 350nm wavelength UV (Polycarbonate cuts less than 300nm wavelength)
• Cure with small UV energy (especially DVD-10 or double side sputtered DVD-5) because Al layer cuts most of UV.
• Excellent adhesion to both L0 (Au, Si, AgX) and L1 (Al).
• Low shrinkage on curing
• Excellent durability
