The document is a technical datasheet for 3M’s transfer adhesive tape model 5792, a high‑tack acrylic pressure‑sensitive adhesive (PSA) applied to a silicone‑coated kraft liner on both sides. It details the tape’s composition, key performance characteristics (initial high tack, resistance to weather, temperature range –30 °C to 70 °C, humidity, solvents, alkalis and acids), and its suitability for porous or textured substrates such as cork, paper, fabric and foam. Physical dimensions are listed (adhesive thickness 0.050 mm, liner 0.080 mm, total 0.130 mm). Typical adhesion test results (ASTM D‑3330) are provided for stainless‑steel substrates, along with maximum liner removal force. Environmental resistance data show stability up to 70 °C and no change after 24 h at 38 °C and 100 % RH. The sheet enumerates common applications (paper splices, label bonding for footwear and apparel, temporary attachment of appliqués, decorative wicking, bonding of technical parts made of polyurethane, PVC, rubber, cork, and foam). Shelf life is 12 months when stored at 22 °C, 50 % RH in original packaging. Processing guidance covers cutting, half‑cutting, lamination (metal‑rubber roll combination, moderate pressure), and handling precautions (high initial tack prevents repositioning, need for knife lubrication, temperature considerations – adhesive stiffens below 10 °C). Surface preparation advice stresses cleaning contaminants with isopropyl alcohol or heptane and notes incompatibility with plasticizers. The document concludes with 3M Brazil contact information for technical support.
