Scotch 4737S Masking Tape 1/2" x 36 yds Blue 3/Case

Scotch 4737S Blue Masking Tape

Scotch 4737S is a blue vinyl masking tape sold in a three-roll carton. Each roll measures one-half inch wide by thirty-six yards long on a three-inch core. It uses a rubber adhesive and a 5.1 mil backing rated to withstand three hundred twenty-five degrees Fahrenheit for thirty minutes. Designed for automotive paint masking where sharp colour separation is critical.

Ideal for multi-tone paint work.

This tape suits professionals creating fine paint break lines on metal or plastic panels, such as two-tone finishes, fascia detailing or rocker-panel accents. The high-temperature resistance supports bake-cycle curing. Buyers needing a basic carton-sealing or general-purpose masking tape should consider a different product because the specialised adhesive and vinyl backing are engineered for precise paint masking rather than everyday sealing tasks.

5.1 mil vinyl backing with 16 lb tensile strength

The 5.1 mil blue vinyl backing combined with a tensile strength of sixteen pounds per inch determines whether the tape holds clean edges under high-temperature paint cycles without tearing or bleeding. This specification is the primary factor in deciding if the product matches the demands of OEM transportation paint masking applications.
