3 Adhesive Transfer Tapes with Adhesive 350 9442 9445 9482PC 9485PC 9485EK 9675 Technical Data September, 2002 These 3M Adhesive Transfer Tapes with 3M Adhesive 350 are a modified acrylic Product Description adhesive ideal for very high-bond strength to many surfaces. They have excellent chemical resistance and bold strength even at elevated temperatures. These tapes are offered with a fiber reinforced adhesive which is important for roll stability in narrow widths. Tapes using adhesive 350 are designed for temperature exposure to 450F (232C) for short periods of time and up to 300F (149C) over long time frames. This adhesive is a good choice for applications which require adhesion to Low Surface Energy plastics, powder coatings and oily metals. Adhesive Construction Product Thickness Number (mils) Liner material - thickness 9442 2.0 (.05 mm) 55 Densified Kraft - 3.2 mils thick 9445 5.0 (.127 mm) 55 Densified Kraft - 3.2 mils thick 9482PC 2.0 (.05 mm) 62 Polycoated Kraft - 4.2 mils thick 9485PC 5.0 (.127 mm) 62 Polycoated Kraft - 4.2 mils thick 9485EK 5.0 (.127 mm) 78 Extensible Polycoated Kraft - 5.7 mils thick 9675 5.0 (.127 mm) 83 Polycoated Kraft lay flat - 6.2 mils thick Note: These thicknesses are nominal values calculated from the adhesive areal density, the actual control value, used in manufacturing. Please note that temperature performance reflects liner off, completed bonds. The poly coated kraft liners melt at lower temperatures and silicone contamination may occur if exposed to high temperature with the liner attached.TM 3M Adhesive Transfer Tapes with Adhesive 350 9442 9445 9482PC 9485PC 9485EK 9675 Note: The following technical information and data should be considered representative Typical Physical or typical only and should not be used for specification purposes.
