    3M Industrial Adhesives and Tapes Division represents more than 50 years of experience in helping companies worldwide apply the science of adhesionto the practicalities of improved product design and manufacturing. The endresults are solutions for managers, engineers, marketers and other decisionmakers who need to get a more competitive product to market while improvingthe process of getting it there.

    In this guide, 3M adhesive science is typically applied to protecting, masking,enhancing, or in other ways modifying surfaces to improve appearance, function,and productivity. You will also find ideas for splicing and temporary holdingapplications such as bundling pipes or hanging poly drapes.

    Here are just a few application ideas:

    Protect against marring and scratches

    Mask for painting or sandblasting

    Splice paper or film

    Resist abrasion or flame

    Conduct heat or electricity

    Repel sticky materials

    Enhance glass with optical accents

    Mark to identify or differentiate

    Color-code for attention

    Cover to stop moisture

    Quiet noise

    Many 3M adhesive solutions are also available for product assembly bonding or holding product components together with strength that rangesfrom permanent to repositionable. You can find assembly solutions in theAdhesives and Tapes Design Guide for Bonding, Attaching, and Fastening.

    Solutions through service...

    3M representatives are located throughout the United States, Canada, and 50 other countries for sales assistance.

    For technical service, a highly trained team is ready to help you evaluate tapes for specific applications.

    A national authorized distributor network provides sales assistance and local product availability. Authorized converters can also help you adapt 3M tapes tomeet special requirements for shape, size, and production.

  • To help you make sure you find the optimum 3M tape or other adhesive-backed product for your particular application, youll want to consider several factors:

    Backing material

    Adhesive type

    Application time and temperature

    Surface characteristics (eg., roughness, surface energy,contours, etc.)

    End use conditions (eg., temperature,UV exposure, abrasion, etc.)

    The information on these two pagesintegrates those factors to help you narrow your selection to fewer productsfor a more in-depth evaluation.

    3M Backing Materials

    In many applications, 3M backings add a second surface that affects howthe underlying surface relates to the environment.

    To optimize that relationship, 3M backings offer a wide choice of performance and handling characteristics.

    Selecting the right product for the job

    Backings CharacteristicsPaper

    Crepe Conformable, easy tear.Flatback Strong, smooth, good for straight line masking.Kraft Strong, some versions are repulpable.Tissue Thin, porous to allow adhesive penetration of sheet.

    Plastic

    Polyester Strong even when thin, chemical resistant, high temperature resistance.

    Polypropylene Resistant to most solvents, conformable, tear resistant.

    Polyethylene Conformable, easy to stretch, chemical/acid/moisture resistant, economical.

  • *Surface energy ranges from high tolow. To illustrate the concept of surfaceenergy, think of water on the unwaxedhood of a car. The unwaxed hood hashigh surface energy and water on thehood flows into puddles. In comparison,a waxed hood has low surface energyand the water beads up rather thanflows out. Similar to water, adhesive on

    a high surface energy surface flows andwets out the surface. Wetting outis required to form a strong bond.

    As a rule of thumb, the higher thesurface energy, the greater the strengthof adhesion.

    Specially formulated adhesives areavailable for low surface energysurfaces. The following illustrations andsurface rankings give you an idea ofrelative surface energy.

    Regardless of surface energy, thesubstrate must be unified, dry, andclean to maximize adhesive contact.

    3M Pressure Sensitive AdhesivesMost of the products in this guidefeature a 3M pressure sensitive

    adhesive that bonds the backing toanother surface on contact. Each adhesive

    has different characteristics that affectproduction and end use performance.

    Applying firm pressure to the bondincreases adhesive flow and contact formore secure bonding.

    Time and temperature will typicallyfurther increase contact andadhesion values.
