3M 7010312804 Fine Line 265 Masking Tape Green 0.25in X 60yd

Product Description

The 3M 7010312804 is the Scotch Fine Line 265 Masking Tape, a polypropylene-backed tape engineered for precision masking in multi-color gel coat applications. At 0.25 inches wide and 60 yards long, the roll delivers a low-profile edge that minimizes gel coat bridging and produces clean, sharp color separation lines. The silicone adhesive bonds immediately to mold surfaces, including those treated with semi-permanent high-slip mold releases, making it well suited to composite fabrication environments. Polypropylene backing resists common solvents and moisture, holding performance through the gel coat cure cycle. This tape is used primarily by fiberglass fabricators and marine composites professionals.

Fine Line 265 is used as an in-mold layout tape during construction of multi-color fiberglass boat hulls and other gel-coated composite parts. Its thin profile prevents gel coat buildup at tape edges, which is critical for high-value finished surfaces. The tape is appropriate for production shops and custom fabricators working with polyester or vinyl ester gel coat systems where clean color breaks and chemical resistance to styrene and related solvents are required.

Key Features

• Thin polypropylene backing provides clean gel coat color separation for in-mold fine line masking
• Silicone adhesive bonds immediately and holds reliably to mold-release-treated surfaces
• Resistant to most solvents, styrene, and moisture throughout the gel coat cure cycle
• Good adhesion to semi-permanent high-slip mold release coatings
• Green color aids visibility during layout and inspection on mold surfaces
• 0.25-inch width suited to tight radius lines and detailed color-break patterns

Compatibility

Designed for in-mold fine line masking on fiberglass composite parts, including multi-color gel-coated boat hulls and panels produced with polyester or vinyl ester gel coat systems.

Installation Notes

Application is typically performed by composites fabricators and marine finishers prior to gel coat spray. Ensure the mold surface is clean and fully cured with the appropriate mold release before laying the tape. Apply with consistent hand pressure to seat the tape edge and prevent gel coat bleed-under. Remove the tape after gel coat has set to the appropriate tack stage per the gel coat manufacturer guidelines to avoid tearing or surface distortion.
