ADHESIVE RESIDUE ON CYLINDER OR SLEEVE
Root cause #1:
Poor cylinder / sleeve cleaning or dust / contamination.
Solution:
Use correct solvent and clean again.
Disadvantages / Factors:
Ethyl Acetate and other heavy solvents can affect the adhesive performance. Scratches, nicks, dents and other surface
abnormalities can affect the tapes performance.

Root cause #2:
Solvent residue.
Solution:
Use correct solvent and allow to dry before mounting.
Disadvantages / Factors:
Sleeve surface may have absorbed cleaning solvent and must be completely dry before mounting tape.

Root cause #3:
Atmosphere.
Solution:
Typical temperature for application: 15 °C to 25 °C, improve on storage conditions. Store in an air-conditioned or cool
place. Rolls should not be left in work environment or hot machine rooms.
Disadvantages / Factors:
Very hot days where temperatures exceed 30 °C.

Root cause #4:
Low adhesion – anchorage of adhesive.
Solution:
Make sure plates have been cleaned correctly – no heavy solvent residue. Contact SM to make contact with Scapa.
Disadvantages / Factors:
Scratches, nicks, dents and other surface abnormalities can affect the tapes performance.

FOAM DELAMINATING

Root cause:
Low foam cohesion or damaged cylinder / sleeves.
Solution:
Change or restore sleeves / cylinder. Alternatively, report to your SM to take the matter further with Scapa.
Disadvantages / Factors:
Scratches, nicks, dents and other surface abnormalities can affect the tapes performance.

PET DELAMINATING
Root cause:
Low adhesion – anchorage of adhesive
Solution:
Make sure surfaces have been cleaned correctly – no heavy solvent residue. Report to SM to make contact with Scapa.
Disadvantages / Factors:
Scratches, nicks, dents and other surface abnormalities can affect the tapes performance.
