Surface Protective Materials E-MASK® R/HR Series

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

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.
