Patco 3900R Embossed Removable Protective Film Tape is a polypropylene film tape used for protective masking on multiple surfaces during lamination molding or machining where clean removal is critical. It is specifically designed for use on textured surfaces. Since the tape is embossed it will stand out in relief (will not have a smooth feel to it). Also Patco labels the tape as clear; however it is not a crystal clear or completely transparent tape because of the embossment (would call it more translucent - please see photos). The tape can also be used as graphics protection for skis snowboards and other outdoor equipment where crisp graphics are critical. It also can be used for screen and direct print (130°C press temp). Patco 3900R is conformable stretchy and heat resistant (it has excellent high-temperature performance). It also does not lift during molding or shaping and removes cleanly leaving no residue after processing under a wide range of conditions. Abrasion and moisture resistant and offers smooth easy unwind. Made in the U.S. NOTES: Sizes shipped will typically be the tape industry standard metric-cut sizes i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). This product s actual size is 72mm x 108 ft. This tape is typically cut to width from log rolls so most sizes ship on non-branded plain white cores. As with any adhesive tape product it is always the user s responsibility to determine that the product is suitable for their intended use; e.g. if you want to remove a product cleanly from a specific type of substrate please test on an inconspicuous area first.
