Adhesive Selection – With the vast array of adhesives and adhesive types available, selection can be difficult. The following five steps can help.<\/h6>\n
    \n
  1. Are there any certifications or qualifications the adhesive must meet?<\/li>\n
  2. Select the correct technology for the application.<\/li>\n
  3. What are the application specific requirements?<\/li>\n
  4. What are the process requirements?<\/li>\n
  5. TEST<\/li>\n<\/ol>\n

    Step 1<\/h4>\n

    Are there any certifications or qualifications the adhesive must meet?
    \nThese include MilSpecs, Commercial Standards, NSF or WRAS (for potable water contact), DVGW for water or gas, or perhaps biocompatibility for a medical device.<\/p>\n

    Step 2<\/h4>\n

    Select the correct technology for the application.<\/p>\n

    Anaerobics<\/strong><\/a><\/h6>\n

    Anaerobics are adhesives that cure when in contact with metal without contact with air. They include threadlockers, thread sealants, retaining compounds, and gaskets. Once yu narrow into one of these categories you can begin adhesive selection based upon the strength, viscosity and other properties.<\/p>\n

    Cyanoacrylates<\/strong><\/a><\/h6>\n

    Cyanoacrylate adhesives cure through reaction with moisture. A cyanoacrylate adhesive works best with rubber or as a plastics adhesive on small components. They bond most substrates well but have poor durability on glass.<\/p>\n

    Toughened Acrylics<\/strong><\/a><\/h6>\n

    Toughened acrylics come in one and two part systems and work well on a wide variety of surfaces. They are quite versatile, working with minimal surface preparation.<\/p>\n

    Epoxies<\/strong><\/a><\/h6>\n

    Available in one<\/a> and two part<\/a>, they offer structural strength on metals but do not excel on plastics. Single part epoxies require ovens to cure them and two part epoxy may require a good bit of time to cure.<\/p>\n

    Polyurethanes<\/strong><\/a><\/h6>\n

    Polyurethanes are known for their high resistance to low temperatures and are excellent for bonding GRP, or glass fibre reinforced plastics. They are impact resistant and cure quickly with the help of special tools.<\/p>\n

    Silicones<\/strong><\/h6>\n

    Silicone adhesive products aren\u2019t incredibly strong, but are quite flexible and resistant to high temperatures. Two-part silicone products tend to work more effectively than the one part products. These are a popular choice for shower and bathtub repairs.<\/p>\n

    Phenolic<\/strong><\/h6>\n

    Phenolic require heat and pressure for the curing process but have peen proven to be excellent in bonding metals, or bonding metals to wood.<\/p>\n

    Polyimides<\/strong><\/h6>\n

    Polyimides are based on synthetic organic chains. These are available in liquid and film form but tend to be more expensive and tricky to handle efficiently. Polyimides are generally excellent with regards to durability under extreme temperatures.<\/p>\n

    Hot Melts<\/strong><\/h6>\n

    Hot melts generally aren\u2019t very strong but work well as an instant adhesive for fast production on components that won\u2019t have much pressure placed on them.<\/p>\n

    Plastisols<\/strong><\/h6>\n

    Plastisols require heat in order to cure and generally produce strong, durable joints.<\/p>\n

    Polyvinyl Acetate, or PVA<\/strong><\/h6>\n

    PVAs are considered an excellent solution for porous materials, including wood and paper. You can find plenty of polyvinyl acetate in packing and shipping companies.<\/p>\n

    Pressure Sensitive Adhesives<\/strong><\/h6>\n

    Pressure sensitive adhesives are durable in various environments and excellent for labeling and on adhesive tapes but really aren\u2019t much of an option for industrial adhesives purposes.<\/p>\n

    Step 3<\/h4>\n

    What are the application specific requirements? See the charts below to assist in adhesive selection.

    Step 4<\/h4>\n

    What are the process requirements?
    \nHow fast does the adhesive need to be dispensed and cured? Is rapid fixturing required? Will UV light pass through one of the substrates? Are the components temperature sensitive? What viscosity is required to fill the gap in the joint? Is that gap too large for optimum strength?
    \nReview these requirements against adhesive selector guides or individual data sheets.<\/p>\n

    Step 5<\/h4>\n

    Test! Once you’ve made your adhesive selection, TEST. When combining the large number of variables that can affect the bond, the only sure way to know is to test the adhesives in actual conditions.<\/p>\n
