Surface Protective Materials SPV-M-4002E

Surface protective materials for metal plates that are suitable for use in laser cutting.


Outline
SPV-M-4002E was developed for the surface protective of stainless steel and other metal plates and is especially suitable for protecting the surface of metal plates during laser cutting. Because SPV-M-4002E uses no polyvinyl chloride film as a base material, it enables a reduction in the corrosion of laser processing ipment caused by chlorine type of gas. SPV-M-4002E features excellent adhesive characteristics and allows top-end surface cutting during laser processing, which was previously not possible.
Features
  • No emission of chlorine gas when incinerated or during laser beam machining, unlike products using PVC film.
  • Easy to laminate regardless of climate.
  • Minimal peeling during laser beam machining (upper surface cutting)
Applications
  • Surface protection of stainless/aluminum plates during transportation/processing.

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.
  • When you paint after peeling off the surface protective material, be sure to check the surface washing, pretreatment, or paint baking conditions to ensure the paint adhesion before usage.
