Surface Protective Materials for Electronics
Optical Elements E-MASK® R・HR Series

Low contamination type developed for surface protective of electronic and optical parts.

Outline

E-MASK® Series and HR Series are polyethylene-based surface protective materials developed utilizing Nitto Denko’s proprietary adhesive synthesis technologies. Both series are especially suitable for surface protective of LCD polarizing films, hard-coat or non-glare treated acrylic plates, and polyester films during processing and transportation.

Features

• Minimal change in adhesive strength following application ensures easy peeling.
• Superior transparency enables inspection of the surface condition of the substrate without removing the tape.
• Tape is pressure sensitive, and easily applied with a laminator.

Applications

• Surface protective for optical film, such as polarizing film (e.g. during LCD shipping)

Precautions

• Avoid sunlight and store at room temperature and moderate humidity.
• Do not press too strong when applying. This may cause the end of the tape to peel.
• If applying to surfaces treated with machining oil, degrease the surface carefully. Any remains will be a cause for surface contamination or adhesive residue.
• For use under severe conditions, please test and evaluate the product thoroughly beforehand.
• Painting, plating, etching, or gluing the surface after peeling the tape may be troublesome due to the small amount of residue of the adhesive. Please inspect under actual situations thoroughly before application.
• Painted boards, depending on conditions such as paint baking, may cause the tape to peel uneasily or peel off the paint together. Please evaluate thoroughly beforehand.
• Surface treated boards such as alumite, depending on treatment conditions, may show different properties (peeling) of SPV. Please evaluate thoroughly beforehand.
• Especially for applications against natural substrate (marble stone, lumber, ｅｔｃ) please contact our sales representative in charge.
