Benefits of two part structural adhesive 2120
- This adhesive is capable of bonding aluminium, steel, engineered plastics and composites together.
- Two part structural adhesive 2120 has high temperature resistance, tensile and shear performance.
- Our acrylic range is also capable of filling gaps up to 4mm whilst maintaining the adhesive’s structural strength and characteristics.
We also have available two part structural adhesive 2105 (5 – 7 minute working life and a 7 – 10 minute fixture time) and two part structural adhesive 2150 (35 – 40 minute working life and a 40 – 60 minute fixture time).
Two part structural adhesives technical information
A methyl methacrylate is the methyl ester of methacrylate acid. Its primary use is to manufacture a number of different plastics, but it is also the main ingredient in our range of adhesive products.
Methacrylate adhesives are supplied in a two part system that, when mixed, offer a controlled cure speed suited to the application. The cured adhesive can offer incredibly high tensile, shear and peel strength, whilst also resisting impact loads at both elevated and sub zero temperatures.
The unique chemistry of our two part structural adhesive 2120 is unrivalled in terms of convenience, ease of use and superior mechanical strength. Use for bonding engineered plastics, composites, steel, aluminium and other alloys.
How to apply two part structural adhesive 2120
Our two part structural adhesive 2120 has a 12 – 15 minute working life with a 20 – 25 minute fixture time. Before dispensing, ensure that surfaces are clean, dry and free of any dirt, dust and grease. For the best results, we recommend using CTA IPA Cleaner Degreaser.
- Use sufficient pressure over the whole surface at room temperature to ensure maximum adhesion to substrates.
- The ideal application temperature is between 15 – 25°C.
- Primers can increase the bond durability and surface tension for difficult to bond materials. We recommend CTA Primer or CTA UV Identifiable Primer to achieve the best results.
- Ensure uniform stress distribution.
