Acrylic Adhesives<\/h2>\n

In the glue biz, we use the term acrylic adhesive loosely, and in doing so, we can create some confusion.\u00a0 There are many types of adhesives based on acrylic chemistry in the form of one and two-component adhesives as well as no-mix resin and activator, even solvent or water-based adhesives, not to mention a variety of acrylic-based pressure-sensitive adhesives (tapes).\u00a0 There are also many adhesives that have an acrylic nature that aren\u2019t categorized as acrylic adhesives.<\/p>\n

Acrylic Adhesives with Other Names<\/h3>\n
    \n
  1. Anaerobic adhesives<\/a> are based on acrylic chemistry but we classify them as anaerobics, not acrylics. Anaerobic adhesives are used for threadlocking, thread sealing, retaining, and gasketing metal components.\u00a0 To cure these materials they need to be in contact with metal and not in contact with oxygen (when the adhesive is confined between two metal surfaces.)<\/li>\n
  2. UV curable adhesives<\/a> may be of acrylic nature, but like anaerobics we generally categorized by the cure mechanism (UV), not the adhesive composition.<\/li>\n
  3. Cyanoacrylate adhesives<\/a> are acrylic but we classify them as cyanoacrylate or instant adhesives. These are also called super glues or crazy glues.<\/li>\n
  4. Methylmethacrylate adhesives are a type of acrylic adhesive that may be grouped into an acrylic category or separated out as MMA\u2019s.<\/li>\n<\/ol>\n

    Rest assured; Permabond and other adhesive manufacturers do not avoid calling these adhesives acrylic adhesives to be deceptive \u2013 it\u2019s simply that due to the variety of acrylic adhesives available, the cure mechanism is often a better descriptor to understand if that particular type of adhesive is suitable for an application.<\/p>\n

    Anaerobic Adhesive Uses<\/h4>\n

    Consider that for anaerobic acrylic adhesives, both substrates should be metal, and the adhesive\/sealant must be confined between two surfaces or cured with an activator.\u00a0 Often anaerobic adhesives are used as weld sealants, which seems contra-indicated as weld sealants are brushed on a warm surface and not confined between two surfaces.\u00a0 When using anaerobic adhesives for weld sealants, the parts are warmed, and low-viscosity adhesive\/sealant is applied and allowed to wick into the small pores in the welds. This does, in fact, deprive the adhesive of enough air to cure.\u00a0 After cure, wipe away the excess or spray it with an activator to cure it off.<\/p>\n

    Another application in which the anaerobic acrylic adhesives leave a residue of adhesives that isn\u2019t between two surfaces is munition sealing.\u00a0 The adhesive that is between the bullet and the shell is cured anaerobically; however, due to the high-speed manufacturing required, spraying with an activator or wiping away residue is not possible. Permabond developed specialty acrylic adhesives<\/a> with NATO approval. These cure anaerobically as well as with UV light \u2013 so is this adhesive an acrylic, an anaerobic, or a UV curable adhesive?\u00a0 Yup, you got it – it is all three!<\/p>\n

    Structural Acrylic Adhesives<\/h2>\n

    For industrial bonding applications, structural acrylic adhesives<\/a>, many manufacturers sub-categorized by application.\u00a0 We define Structural Adhesives <\/strong>as adhesives that can support a structural load when fully cured.\u00a0 <\/strong><\/p>\n
