Note 2: Backside (BS) adhesive is on the exterior of the roll, exposed when liner is removed. Note 3: The caliper listed is based on a calculation from manufacturing controlled adhesive coat weights using a density of 1.012 g/cc. Features * This tape has a film carrier which can add dimensional stability to foams and other substrates and also makes it easier to handle the tape during slitting and die-cutting. * 3MTM Double Coated Tape 9474LE features a dual liner for ease in selective die cutting. * The bond strength of 3MTM Laminating Adhesive 300LSE increases as a function of time and temperature, and has very high initial adhesion. Application Ideas * Foam to powder coated painted surfaces. * Low surface energy plastic adhesion. * Lens bonding applications. 3 3MTM Double Coated Tapes 9474LE * 9495LE Typical Physical Properties and Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.

Firm application pressure and moderate heat, from 100F (38C) to 130F (54C), will assist the adhesive in developing intimate contact with the bonding surface. To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.* 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 generally satisfactory. *Note: Carefully read and follow the manufacturer's precautions and directions for use when working with solvents. These cleaning recommendations may not be compliant with the rules of certain Air Quality Management Districts in California; consult applicable rules before use. Application Equipment To apply adhesives in a wide web format, lamination equipment is required to ensure acceptable quality. To learn more about working with pressure-sensitive adhesives please refer to technical bulletin, Lamination Techniques for Converters of Laminating Adhesives (70-0704-1430-8).

Environmental Performance Humidity Resistance: High humidity has minimal effect on adhesive performance. No significant reduction in bond strength is observed after exposure for seven days at 90F (32C) and 90% relative humidity. UV Resistance: When properly applied, nameplates and decorative trim parts are not adversely affected by exposure to direct sunlight. Water Resistance: Immersion in water has no appreciable effect on the bond strength. After 100 hours at room temperature, the high bond strength is maintained. Temperature Cycling Resistance: High bond strength is maintained after cycling four times through: 4 hours at 158F (70C) 4 hours at -20F (-29C) 4 hours at 73F (22C) Chemical Resistance: When properly applied, nameplate and decorative trim parts will hold securely after exposure to numerous chemicals including oil, mild acids and alkalis. Storage Store in original cartons at 70F (21C) and 50% relative humidity. Shelf Life If stored under proper conditions, product retains its performance and properties for two years from date of manufacture.
