  • Superior wettability allows easy reapplication.
  • Stable adhesion lasts without degradation over time.
  • Superior in low staining properties.
  • Excellent static control to cause no damage to sensors and repel foreign materials at peeling (AW303EB/AW343EB)

  • 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.
