Araldite 2021-1 and 2022-1

Extend Performance in Automotive Assembly Applications

Huntsman introduces two new Araldite adhesives with extended performance in automotive assembly applications. Araldite 2021-1 and 2022-1 will see vehicle manufacturers and the automotive aftermarket benefitting from increased levels of productivity and performance on structural adhesive applications.

In 2015, the global automotive adhesive and sealant market was valued at USD 5 million. With factors including vehicle safety, light weighting and fuel economy continuing to prevail under ever stringent standards and regulations, it’s expected that this market will grow at a compound annual rate of 9% up to 2020.

The two-component, toughened, methacrylate adhesive systems replace Araldite 2021 and 2022 respectively, with the new products offering measurable improvements. Both are well suited for use on auto interior modules, exterior finishes, lights, headlamps, repairs and aftermarket operations with significant features including improved elongation at break, notable toughness and resilience to vibrations, dynamic loading, mechanical impact and assembly of dissimilar substrates.

Non-sagging and gap-filling properties enable easy processing and make vertical applications possible. These products also provide good shear strength across various substrates and temperatures up to 100˚C along with tolerance of non-ideal surfaces which enhance their processing capabilities while increasing productivity and performance levels. Following on from stringent testing Araldite 2021-1 and 2022-1 deliver good lap shear strength across a variety of substrates and a wide range of temp eratures

Another significant change is the new, adhesive packaging design. The innovative cartridge has been created to include a re-designed application nozzle, which successfully stops cross-contamination between the resin and activator, preventing the cartridge being blocked by cured adhesive residues after the first use.

In order to support this fast moving market, Huntsman recently consolidated its Methyl Methacrylate (MMA) adhesives manufacturing into a single dedicated plant in the EU, simplifying the business’ internal supply chain and ensuring faster deliveries to customers in line with anticipated demand for adhesives in the future.
