3M™ Thermal Transfer Acrylate Label Material 3921 consists of a non-topcoated acrylate facestock designed for thermal transfer printing and withstand high temperatures and resist chemicals such as those found in the fabrication of printed circuit boards (PCBs).
High temperature resistant labelstock 3921 is recommended for thermal transfer imaged labelstock applications where a high durability and superb resistance against highest application temperature is required. The acrylic based film is resistant to outdoor weathering, UV-light and many solvents as well as being dimensionally stable. The matte white facestock provides a very good contrast which leads to a high first readability rate; even of high density barcodes.
