Shurtape CP-743 Matte Black Paper Tape is a photographer's matte black masking tape. It features an opaque, matte surface for light-free masking and has high quick stick & adhesion when reproducing photographs. Shurtape CP743 Paper Tape is used for photographic reproduction work: cropping and edging negatives; positioning negatives for contact printing; and sealing camera bellows and film holders against light leaks. Reliable tape for use in photo studios, film processing laboratories, as well as in home dark-rooms. CP743/P743 Masking Tape is also recommended for use as a chart tape. It features an easy, consistent unwind and is hand tearable. Also because CP-743 features a clear adhesive no white will be visible when looking at the tape from the side unlike a gaffers tape which has white adhesive which can sometimes be partially visible when looking at the tape from that angle. It is now manufactured by Shurtape and used to be referred to as Permacel P-743.

** special order sizes are not returnable (and non-cancelable if material has been ordered or cut before the cancellation request was made)
** minimum requirements are due to the fact that the product size is non-stock
** if a particular size has a minimum item requirement please only purchase that size in multiples of that minimum, e.g. if the minimum is 12 then purchase as 12, 24, 36, etc.
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
