Permabond structural acrylic adhesives are suitable for a variety of applications:
They are ideal for structural bonding of metals, composites, plastics, glass, wood and other materials. Permabond’s structural acrylic adhesives have excellent durability. They resist tensile, peel, cleavage, and impact forces as well as resisting the stresses of differential thermal expansion found when bonding dissimilar materials.
They are formulated with resistance in mind, so are suitable for applications that involve exposure to oils, greases, moisture and weathering.
Typical applications include:
● Magnet bonding (particularly for electric motors)
● Metal & glass furniture manufacturing
● Street signs
● Rear view mirror attachment
● Structural bonding - e.g. aluminium panels
● Signs
Permabond offers several types of structural acrylic adhesives:

 

● No-Mix Adhesive & Initiator. Initiator is applied to one of the bonding surfaces and the adhesive to the other. Suited to bonding tight fitting parts, this system provides a long open time and a short cure time.
● Bead on Bead Part A & Part B. A bead of one part is applied directly over a bead of the other part. No mixing is required. When the two components are pressed together, enough mixing will take place to cure the adhesive.
● 2-Part. Adhesive is supplied in convenient 1:1 cartridges for use with a dispensing gun. Adhesive is dispensed directly onto the substrate material via a static mixing nozzle.
● Single Component - No mixing required. These adhesives are simple to apply and cure with or without an activator (activator can be used to reduce cure times to seconds and to cure through larger gaps).
Benefits:
● Extrememly high strength bonds increase design possibilities.
● Excellent durability to impact, peel, shear, and thermal expansion increases part life.
● Room temperature cure eliminates ovens and other equipment
● Rapid cure increases daily output to reduce production costs.
● Bond a wide variety of substrates to increase design freedom.
● Many non-flammable grades available.
● Technical support- application specialists available for assistance with joint design, adhesive selection and production process.
