5180C PolyMask
5180C PolyMask is a 0.005″ (5 mil) clear polyolefin film backed with low-density polyethylene and coated with a custom-formulated premium aqueous-based acrylic adhesive. The soft, aggressive adhesive matrix delivers 80 oz/in adhesion to steel — the highest in the PolyMask protective film series — with medium-high peel values that exhibit low build over time. The film is suited for surface protection on plastics, glass, metals, cool painted metal, low-gloss painted metal, textured HPL/LPL, and HP/LSE powder coatings including DuPont Kynar® finishes.

- Surface protection of plastics, glass, and metal substrates during fabrication and handling
- Cool-painted and low-gloss painted metal protection where higher peel adhesion is required
- Textured HPL and LPL laminate surface protection during converting and shipping
- Powder coating HP/LSE finish protection (e.g., DuPont Kynar®)
- Lightly textured surface masking where standard low-tack films do not anchor reliably
Common industries: Architectural panels, laminate manufacturing, painted metal fabrication, powder-coating operations, surface protection converting.
5180C PolyMask is a high-adhesion temporary protection film designed for surfaces where low-tack masks like 4040 cannot achieve adequate hold — particularly textured laminates, low-gloss painted metals, and powder-coated finishes such as DuPont Kynar®.
The construction pairs a 0.005″ clear polyolefin film with a low-density polyethylene backing, coated with a custom-formulated premium aqueous-based acrylic adhesive whose matrix is described as soft and aggressive. The 80 oz/in adhesion to steel is the highest in the PolyMask family, calibrated for reliable adhesion on substrates with surface texture or low surface energy that resist standard protective films.
A defining performance characteristic is the medium-high peel values combined with low build over time — meaning the adhesive does not increase its bond strength significantly during prolonged dwell, supporting clean removal even after extended storage or shipping periods. This contrasts with conventional aggressive PSAs which typically exhibit strong bond build that can make removal difficult or cause adhesive transfer.
The film is suitable for both lightly textured surfaces and some smooth-surface applications. Tensile strength is 2,550 psi with 575% elongation per ASTM D882, providing handling durability and conformability over textured contours.
What differentiates 5180C from other PolyMask protective films?
5180C is the highest-adhesion grade in the PolyMask family at 80 oz/in to steel, with a custom-formulated aqueous acrylic specifically designed for textured surfaces and low-gloss / LSE finishes including powder coatings like DuPont Kynar®. The defining performance feature is the combination of medium-high peel adhesion with low build over time — supporting reliable hold during shipping while still permitting clean removal after extended storage. 5188 PolyMask, by comparison, delivers 12 oz/in for smooth flat/satin-gloss surfaces.
Why is adhesion important when selecting this film?
For surface protection films, the adhesion-to-build relationship matters as much as the absolute adhesion value. 5180C's "low build over time" characteristic is critical — many aggressive adhesives become too strong to remove cleanly after extended dwell. The 80 oz/in initial adhesion provides reliable hold on difficult substrates while controlled build behavior preserves the clean-release functionality that defines a protection film.
What is the operating temperature range for 5180C?
The TDS does not publish a service temperature range for this film. Specifiers requiring temperature service data should contact H-O Products directly.
Is 5180C suitable for textured or low-surface-energy substrates?
Yes. The TDS specifically identifies textured HPL, textured LPL, and powder coating HP/LSE finishes (including DuPont Kynar®) as target applications. The aqueous-based acrylic with soft, aggressive matrix is custom-formulated for these challenging surfaces. No specific regulatory compliance standards are listed on the TDS for this material.
How should 5180C be specified?
Specify product (5180C PolyMask Protective Film), thickness (0.005"), backing (low density polyethylene), color (Clear), target substrate (particularly noting any textured, low-gloss, or LSE finishes), compliance requirements, dimensional tolerances, and finished format.
