Scapa 425 Pro-Grade Gaffers Tape

Product Description

When you need excellent adhesion, Scapa 425 Pro-Grade Gaffers Tape is a great choice. This the most adhesive gaffers tape we sell at FindTape.com, which makes it adhere for longer and more securely than other gaffers tapes. This Scapa gaffers tape is a waterproof, vinyl-coated cloth tape featuring a single coating of rubber pressure adhesive. This material gives it an exceptionally high tensile strength and high tack and makes it easy to unwind. It's a black gaffers tape featuring Scapa's low-gloss backing to reflect the least amount of light, making it great for a wide range of applications in TV, film and photography. Note: FindTape can offer Scapa 425 gaffers tape in non-standard sizes due to our converter receiving the tape in wide width log rolls and because of that those cut rolls will be shipped on non-branded plain white cores.

QUESTION: Is this better for bookbinding than Shurtape P-628 Industrial Grade Gaffers Tape?
ANSWER: The best gaffers we sell for bookbinding would be Shurtape P-672 (see https://www.findtape.com/p117/) because of its very high tensile strength. Thank you.

Made in the USA
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.
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.
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.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
