About this item
SKU T9344737S3PK — 36 yds. × 36 yds., 5.1 Mil, Blue. Sold as a case of 3, shipped from US warehouses.
3M 4737S masking tape delivers crisp paint break lines on metal and plastic surfaces up to 325°F. This 3-pack case features 5.1 mil blue vinyl backing with aggressive rubber adhesive for reliable adhesion during high-temperature automotive applications. Each roll provides 36 yards of 3/4 " width for precision masking on multiple-color jobs.
Common questions
How does the rubber adhesive prevent paint bleed-through during spray application?
The aggressive rubber adhesive on 3M 4737S creates an immediate, firm bond to metal and plastic surfaces without requiring extended dwell time. This minimizes micro-gaps where paint particles can seep underneath, maintaining sharp paint break lines even with standard spray pressure and gun distance. For best results, apply tape to clean, dry surfaces and press firmly along edges.
Will this tape hold up during 325°F cure cycles without lifting or leaving residue?
Yes. The 5.1 mil vinyl backing and rubber adhesive formulation are specifically engineered for high-temperature masking in OEM paint shops. The tape maintains adhesion through 30-minute exposure at 325°F and leaves minimal residue when removed while surfaces are warm, reducing cleaning time and material waste.
Is this tape compatible with standard packing line dispensers?
3M 4737S is compatible with most manual and pneumatic tape dispensers designed for 3/4" width rolls. The 3-pack configuration allows you to load multiple dispensing stations simultaneously, improving line efficiency. Verify your dispenser's core size compatibility (standard 1" or 2" cores) before ordering.
What's the difference between 4737S and other masking tapes for automotive applications?
3M 4737S is formulated specifically for transportation OEM masking where fine line precision is critical. The blue vinyl backing provides visibility for positioning, the rubber adhesive prevents shifting on curved surfaces, and the temperature resistance supports thermal cure schedules. This makes it ideal for facia, rocker panels, and multi-color applications where paint defects directly impact vehicle grade and warranty risk.
