The liner protecting the adhesive is removed and preferably without touching the adhesive, the fastener is applied to the surface to obtain initial contact between the adhesive and substrate. Exposure of the adhesive to ambient conditions without the protective liner, before applying to the surface, should be minimized as initial adhesive tack may decrease. Flexible materials should be lying on a hard flat surface so as to permit uniform adhesive contact with the surface. Use of a rubber hand roller, press platen or similar device is recommended to ensure full adhesive contact with the surface. Approximately 4.5 pounds of force per square inch, (310 grams per square centimeter) is recommended to increase adhesive contact, improving bond strength. For all adhesive applications, it is important to ensure that the edges are rolled down to reduce the chance of edge lifting. * It is essential that the user evaluate this product to determine whether it is fit for a particular purpose and suitable for the user's method of application -3- 3MTM Hook and Loop Reclosable Fasteners SJP7401 Loop * SJP7402 Hook * SJA7501 Loop * SJA7502 Hook Performance Characteristics Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. Solvent Resistance: The plain backed nylon/polyester components resist occasional attack by most common solvents and alkaline solutions. Acid solutions may cause deterioration of the fastener. The adhesive on 3MTM Hook and Loop Reclosable Fasteners SJA7501 and SJA7502 may be compromised by many common laboratory solvents and transportation fluids (gasoline, motor oil, etc.). Where solvent resistance is important it is suggested that the customer evaluate 3MTM Hook and Loop SJ3571, SJ3572, SJ3576, SJ3577 or many of our 3MTM Dual LockTM Reclosable Fastener products to determine if the actual adhesive performance meets their application requirements. Plasticizer Resistance: The adhesive on Reclosable fasteners SJA7501 and SJA7502 is not recommended for attaching to many common flexible vinyl's or other materials containing plasticizing materials. If plasticizer resistance is desired 3MTM Hook and Loop SJ3522 and SJ3523 or many of our Dual Lock products can be evaluated. Flammability Resistance: If you need 3MTM Reclosable Fasteners that meet many the standard flammability tests (such as FAR 25.853) SJ3418FR, SJ3419FR, SJ3486FR and SJ3487FR for sewing applications and SJ3518FR, SJ3519FR, SJ3586FR and SJ3587FR for pressure sensitive applications. Environmental Effects: Temperature as low as -20F (-29C) increases the typical closure strengths. The adhesive on 3MTM Hook and Loop Reclosable Fasteners SJA7501 and SJA7502 has not been formulated to withstand varying temperature, humidity and ultraviolet exposure conditions. If applications such as exposure to high temperatures, humidity or ultraviolet light are desired, our 3MTM ScotchmateTM SJ3571, SJ3572, SJ3576 or SJ3577 or many of our Dual Lock products, such as SJ3560, may be evaluated. Application Ideas * 3MTM Hook and Loop Reclosable Fasteners SJP7401 and SJP7402 can be used in sewing applications where average strength fasteners will be sufficient. * 3MTM Hook and Loop Reclosable Fasteners SJA7501 and SJA7502 provide a rubber based adhesive solution for applications at ambient temperatures where minimal adhesive requirements occur. Because product performance will depend on actual conditions within any specific application, it is essential that the user evaluate the 3M product to determine whether it is fit for a particular material purpose and suitable for the user's method of application. * This product is non-returnable so verify that it performs to your requirements. -4- 3MTM Hook and Loop Reclosable Fasteners SJP7401 Loop * SJP7402 Hook * SJA7501 Loop * SJA7502 Hook Technical Information The technical information, recommendations and other statements contained in this document are based upon tests or experience that 3M believes are reliable, but the accuracy or completeness of such information is not guaranteed.
