ARALDITE® 2081: The benchmark plastic bonding solution
To ensure effective adhesion, it is essential to carefully prepare the surface of the plastics to be joined before any application.
With this in mind, Samaro and its partner Socomore recommend the use of Diestone DLS, a fast-evaporating cleaning and degreasing solvent that guarantees optimum assembly without leaving greasy residues.
In the demanding field of plastic bonding, choosing the right adhesive can mean the difference between a strong, durable bond and potential problems with strength and durability. Among the many options available on the market, Huntsman’s Araldite 2081 methacrylate adhesive stands out as a leading solution, offering a unique combination of features and benefits that make it ideal for bonding plastics (excluding PP and PE) in a variety of industrial applications.
Distinctive features of Araldite 2081
Araldite 2081 methacrylate adhesive has a number of distinctive features that put it at the top of the list for plastic bonding. Firstly, its low odour, reduced by up to -90% compared to conventional MMA, makes it a preferred choice in sensitive environments where chemical fumes need to be minimised. This makes it particularly suitable for indoor and confined applications.
In addition, Araldite 2081 offers enhanced resistance to dynamic stresses, making it an ideal choice for applications subject to vibration, shock or repeated loads. Its resistance to dynamic stress is a key advantage in sectors such as the rail industry, where reliability and durability are essential.
What’s more, Araldite 2081 is EN45545-2 approved, meeting HL3, Class R1 and R7 requirements for the rail industry. This certification attests to its ability to meet the stringent safety and performance standards required in this sector.
Finally, Araldite 2081’s 70% elongation at break makes it a flexible adhesive that can absorb mechanical and thermal stresses, reducing the risk of premature assembly failure.
