![]() ![]() Mounting tapes are designed specifically for the purpose of mounting artwork to a mat or backing board. ![]() Still, if you want to create a frame package that is entirely acid free, acid free ATG tape is the answer. So adhesive transfer tape is rarely used for mounting artwork, which can only lead to the conclusion that it rarely contacts the artwork, and since the danger from acid burn occurs when the adhesive is in contact with the artwork, the need for an ATG tape that is acid free is somewhat questionable. This is better done with self-adhesive foam board or PMA. Moreover, adhesive transfer tape can only be applied in long strips, which means the bond will not be uniform across the back of the item to be mounted.įor permanent mounting it’s preferable to coat the item with adhesive, creating a uniform bond to avoid air pockets and creases. If adhesive transfer tape is used for this purpose it should only be used to mount artwork that is unlikely to increase in value, such as posters or easily reproduceable photographic prints. The very act of taping artwork permanently to something devalues it. But remember, adhesive transfer tape is rarely used to mount artwork to a backing board because it creates a permanent bond by sticking the artwork permanently to the backing so that it cannot be removed. Given enough time, in direct sunlight and high humidity, it can cause a hazy brown effect called “acid burn” that can devalue and ruin artwork. Read more Acid Free ATG TapeĪcid free ATG tape offers an adhesive that contains no harmful acids. Yet, for long term economy there is no real advantage to buying handheld adhesive transfer tape except to avoid the one time cost of purchasing a tape applicator gun, because ATG tape actually costs a few cents less per yard than handheld adhesive transfer tape. With this tape, the adhesive is “interior wound” which means the adhesive is turned to the inside as it comes off the roll, making it less of a hassle to deal with. This tape is for those who prefer to work with adhesive transfer tape manually. Read more Handheld Adhesive Transfer Tape The roller rolls out the double-sided adhesive, peeling up the liner as it goes, threading it back into the gun. To operate the ATG gun you squeeze the trigger, releasing the roller and then press the nose against the surface to be glued and pull back. Because both sides of the adhesive are in play these tapes are often referred to as “double sided adhesive transfer tapes.” ATG TapeĪ type of adhesive transfer tape where the adhesive is “reverse wound” meaning the adhesive is wound on the outside of the roll, making it cumbersome to work with manually but ideal for use in an adhesive transfer gun where the tape is threaded around the roller at the nose of the gun adhesive side out. When the liner is peeled away, the other side of the adhesive is exposed, so that a second item (be it a mat blank or dust cover) can be pressed against it and stick. They are applied by pressing the tape firmly against the surface and then peeling off the strip of release paper, called the “liner”, that backs the adhesive. ![]() ![]() They are characterized by high initial tack (which means they grab quickly) and a secure, long-lasting bond. Adhesive Transfer TapesĪdhesive transfer tapes are used primarily for sticking double mats together, attaching dust covers, gluing spacers and fillets in place, and mounting artwork to a backing board. Here’s a guide to help you when comparing tapes and adhesives for picture framing. So many different tapes, so many applications. ![]()
