'Scotch 568' has been discontinued.
Product Description
Scotch 568 Positionable Mounting Adhesive (PMA) is a repositionable synthetic mounting adhesive that can achieve powerful dry mounting without the use of heat, sprays, or giving off chemical odors. Formulated for use with sensitive papers and colors that can’t hold up to heat, as well as thin papers, digital printouts, and more. Reposition until the desired alignment is achieved and then use the included squeegee to apply pressure and create a permanent bond. Available in 50 foot long rolls in 11, 16, and 24 inch widths. A brand of 3M.

QUESTION: Now that this is discontinued what else can people use?
ANSWER: We’ve asked 3M and they have no suggested alternatives. We’ve also checked with different tape converters we work with and they also do not have any direct replacements. The closest we would sell would be Scapa’s 4450 product seen online at
https://www.findtape.com/p335/?tid=30. However while that product offers low adhesion it’s really not spec’d as repositionable/removable so don’t think it would really be a good fit unfortunately.

QUESTION: Is this acid-free?
ANSWER: No, 3M does not mention that the tape is pH-neutral (acid-free). Thank you.

User Reviews
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.
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
Lower gauge gloves are heavier - have thicker construction, fewer stiches knitted per inch and offer less dexterity.
Higher gauge gloves are lighter - have thinner/finer construction, more stitches knitted per inch and offer more dexterity.
Gloves offered typically runs from 7 to 18 (12 and 13 are in the middle of the scale).
