3M 7010373932 Scotch Fine Line 265 Masking Tape Green 1/2 in

Product Description

The 3M 7010373932 is the Scotch Fine Line 265 Masking Tape, a thin polypropylene plastic tape engineered for precision masking in high-value multi-color gel coat applications. The silicone adhesive bonds immediately to mold-release surfaces, including semi-permanent high-slip mold releases, and holds reliably through the gel coat process. At 1/2 inch wide and 60 yards long per roll, this tape delivers clean, sharp color separation lines in fiberglass layup and mold environments where chemical exposure and moisture are constant factors.

This tape is primarily used in marine and composite fabrication settings as a layout tape for in-mold fine line masking of gel coated fiberglass boat hulls. Its thin, low-profile polypropylene backing conforms to contoured mold surfaces, making it a standard choice for multi-color hull panels where crisp transitions between gel coat colors are required. Fabricators in boatbuilding and composite shops apply this tape directly over mold release agents without loss of adhesion or edge lift.

Key Features

• Thin polypropylene backing provides precise gel coat color separation for in-mold fine line masking
• Silicone adhesive bonds immediately and holds reliably to mold-release-treated surfaces
• Superior chemical resistance to gel coat resins, most solvents, and moisture
• Low-profile tape minimizes gel coat bridging at the tape edge
• Green color for easy visual identification during multi-color layout work
• 60-yard roll length reduces mid-job roll changes on large hull panels

Compatibility

Designed for in-mold fine line masking on gel coated fiberglass surfaces, including molds treated with semi-permanent high-slip mold release agents. Typical applications include multi-color gel coat layouts on fiberglass boat hulls and composite fabrication panels.

Installation Notes

Apply in clean, dry mold environments by composite fabricators or marine finishers following standard in-mold masking procedures. Ensure the mold release layer is fully cured before tape application to confirm proper adhesion. Remove tape at the angle and pace specified by your gel coat material manufacturer to maintain clean edge lines. Do not apply over uncured or tacky release films.
