(76.2 mm) Features The high density polyethylene carrier in this product is hand-tearable, and provides dimensional stability and improved handling with ease of die-cutting and lamination compared to adhesive transfer tapes. 3M Adhesive 760 provides high tack adhesion to a variety of substrates, including metals, plastics and glass as well as providing clean removal from many surfaces. Tape components are in compliance with Title 21 of the code of Federal Regulations (21 CFR) as indirect food additives. Application Techniques Bond strength is very dependent on the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact and thus improves bond strength. To obtain optimum adhesion, the bonding surfaces must be clean, dry, and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.* *Note: Carefully read and follow the manufacturers precautions and directions for use when working with solvents. These cleaning recommendations may not be in compliance with the rules of certain air quality management districts in California consult applicable rules before use. Ideal tape application temperature range is 70F to 100F (21C to 38C). Initial tape application to surfaces at temperatures below 50F (10C) is not recommended because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is satisfactory Application Ideas Core starting on metal cores Splicing rough surface materials or coated materials Temporary holding to wood, metal, plastic, concrete, linoleum or other surfaces where clean removal is required. Note: Bond strength can exceed coating adhesion that may cause coating delamination upon removal of tape. Bonding to UV cured coatings Splicing carpet backing End tabbing of metal coils - 2 -
