Product Description

Scapa 571 Silicone Splicing Tape is a thin polyester film, single-coated on one side with a custom-formulated silicone pressure sensitive adhesive (opposite side of the film utilizes a standard non-silicone coating). The silicone adhesive provides high initial tack and ensures an excellent bond to silicone coated substrates. This translucent shear-resistant product is pink to enable prompt splice identification and has a soft, conformable adhesive that adheres well to irregular surfaces. It is used for splicing of silicone release papers, films, and other substrates; general-purpose bonding; high-temperature masking; and chemical masking.

Scapa 571 features include:

  • Excellent adhesion to silicone coated substrates.
  • High initial tack which insures a good bond.
  • Conforms to achieve good contact to surfaces being spliced.
  • High shear resistance for a strong bond.
  • Color of tape enables prompt splice identification.
  • Is resistant to many chemicals.
Made in Canada.
* Multiple cases may be shipped per package in order to minimize the charge for shipping.

Alert Roll Sizes/Widths

Please note that tape rolls are NOT guaranteed to be splice-free. Tape rolls are typically cut to standard tape industry metric-cut sizes - or approx 5% narrower than the nominal size (i.e. 24mm per 1-inch of nominal width ordered).

Please contact us to inquire about pricing for full-cut widths (e.g. a 6 inch roll cut to exactly 152mm instead of 144mm).

Nominal Tape Widths vs Actual Widths

Nominal vs. Actual Widths Zoom In

Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:

  • 1" Nominal width = 15/16" (24mm) Actual width
  • 2" Nominal width = 1-7/8" (48mm) Actual width
  • 3" Nominal width = 2-13/16" (72mm) Actual width

Note that tape rolls are NOT guaranteed to be splice-free.

Custom Tape Widths
May be Available!

  • Need custom sized or "full-cut" width tapes? Many of our tapes come to our converter as full wide width "log rolls" (not pre-cut), and can be custom cut to widths not shown in the pricing table.
  • Contact us today for pricing and minimum requirements to order your desired tape in a custom width.
  • Please note that since this tape comes in "log roll" format most rolls ship on a plain white core (i.e. with no branding or text inside the core).

Question & Answers

QUESTION: Hello there, I am looking for a tape that will adhere to parchment paper. I am an artist and I wrap my small paintings for shipping in Reynolds brand parchment paper. I currently wrap a bow around smaller work but need something to hold the paper on larger pieces.
ANSWER: Parchment paper has a silicone-coating so the only type of adhesive that will bond to that will be a tape coated with a silicone adhesive. Most double-sided tapes come on a silicone-coated release liner (since if the adhesive side of the tape were to be coated with a standard rubber or acrylic adhesive it won’t bond to the silicone-coating on the release liner) - and that is the type of tape you will see on those rolls which keep the tape from unwinding on itself. You can see the different tapes we sell for that at: Thank you.

User Reviews

Scapa 571 Silicone Splicing Tape
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
