    Product Description

    3M™ Adhesive 200MP is a popular choice for graphic attachment and membrane switch applications because it has excellent quality, consistency and durability. In addition, as a result of 3M’s innovative, proprietary process, 3M adhesive 200MP also offers the following excellent performance characteristics.

    Clarity (virtually free of vapor inclusions that are commonly found in adhesives produced by the traditional solvent coating technique).

    Excellent high temperature performance as well as excellent shear strength (that minimizes edge lifting and slippage of parts). Excellent resistance to harsh environments; this adhesive can withstand splashes of organic solvents, weak acids and bases and salt water, cleaning solutions, germicidals, disinfectants, oils, etc. In addition, it performs well after exposure to humidity and hot/cold cycles.

    Provides some initial repositionability when bonding to plastic parts (not metal) which allows graphic parts to be lifted and repositioned if initial alignment is incorrect.

    Finally, this adhesive family is provided with a variety of liner configurations to help ensure excellent process flexibility.

    Constructions

    1The adhesive color is transparent with a very slight yellow cast. The yellow cast is not typically visible in a single adhesive layer.

    2The thickness listed is based on a calculation from manufacturing controlled adhesive coat weights using a density of 1.012 g/cc. While past data pages have listed nominal thicknesses of 2 and 5 mils, the coat weight (and theoretical caliper) has not changed.

    3Where two liners are listed (double-linered products, useful for selective die-cutting), liner 1) is the primary (stays with the die-cut part); liner 2) is the secondary (removed first). The polycoat on one side of the heavy linered products (83#) was changed to balance the liner. This balanced sheet will provide an improvement to the flatness of products made using the heavy liner.

    4Typical liner release value, in grams/inch, tested at 90 ipm. For additional double coated product constructions (adhesive/carrier/adhesive) using 3M™ Adhesive 200MP, please refer to the data page for 3M™ Membrane Switch Spacers (70-0707-1195-0) and the data page for Double Coated Tapes with 3M™ Adhesive 200MP (70-0709-3792-8).

    Application Techniques

    For maximum bond strength (during installation of the final part) the surface should be thoroughly cleaned and dried. Typical cleaning solvents are heptane* (for oily surfaces) or isopropyl alcohol* for plastics. Use reagent grade solvents since common household materials like rubbing alcohol frequently contain oils to minimize the drying affect on skin and can interfere with the performance of a pressure-sensitive adhesive.

    *Note: Carefully read and follow the manufacturer’s 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.

    It is necessary to provide pressure during lamination (1.5-20 pli recommended) and during final part installation (10-15 psi) to allow the adhesive to come into direct contact with the substrate. Using a hard edged plastic tool, which is the full width of the laminated part, helps to provide the necessary pressure at the point of lamination. Heat can increase bond strength when bonding to metal parts (generally this same increase is observed at room temperature over longer times, weeks). For plastic parts, the bond strength is not enhanced with the addition of heat.

    The ideal adhesive application temperature range is 60°F (15.6°C) to 100°F (38°C). Application is not recommended if the surface temperature is below 50°F (10°C) because the adhesive becomes too firm to adhere readily. Once properly applied, at the recommended application temperature, low temperature holding is generally satisfactory (please refer to section VII of the Typical Physical Properties and Performance Characteristics).

    When bonding a thin, smooth, flexible material to a smooth surface, it is generally acceptable to use 2 mils of 3M™ Adhesive 200MP. If a texture is visible on one or both surfaces, the 5 mil 3M adhesive 200MP would be suggested. If both materials are rigid, it may be necessary to use a thicker adhesive to successfully bond the components. 3M™ VHB™ Acrylic Foam Tapes may be required (please refer to the data page 70-0709-3830-6).

    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).

    Application Ideas

    • Long term bonding of graphic nameplates and overlays (“subsurface” printed polycarbonate or polyester) to metal and high surface energy plastics in the aerospace, medical and industrial equipment, automotive, appliance and electronic markets.

    • Bonding metal nameplates and rating plates in the aerospace, medical and industrial equipment, automotive, appliance and electronic markets.

    • Bonding graphic overlays for membrane switches and for bonding the complete switch to the equipment surface.

    • High speed processing of parts in the medical, telecommunications and electronics markets (medical components, durable labels, flexible circuits).

    • Lamination to industrial foams for rotary die-cutting of small gaskets for industrial and electronics markets.
