The Brady Shadow Marking Tape is a general purpose marking tape that creates dark, opaque lines on light surfaces for labeling and identification. It has an acrylic adhesive and is made of vinyl. The tape comes in multiple widths from 1/4 inch to 1 inch and in lengths of 36 yards. It can withstand temperatures from -20F to 200F. The tape can be used on plastic, glass, metal, rubber, and more. It conforms well to irregular surfaces. The acrylic adhesive sticks well but can be removed cleanly.
