Benefits from the Araldite LY3031

ARALDITE 2033 structural adhesive reaches the highest level of fire safety standards for the rail industry

• One-minute part to part cycle time
• Fibre volume content up to 65% and Void-free parts
• Simple processing of heavy-tow industrial fabrics
• Reduced equipment investment (low pressure process)
• Reduced waste
• Complex (2.5+D) parts

Huntsman Advanced Materials has released an App which offers insight on the content, techniques and value of simulation, illustrated by a number of case studies.
Users of the App get access to all the basics of the approach through to specific examples of how a variation in process parameters might affect outcomes, for example in identifying the best injection temperature to minimise filling time.

ARALDITE 2033 structural adhesive reaches the highest level of fire safety standards for the rail industry
At the assembling level too, there are continuous improvements programmes which contribute to the one-stop resource and respond to the demands of key market sectors for higher standards.
In the rail industry, for example, fire safety standards continue to harmonise across international borders, bringing with them a more demanding performance level for all.
In its range of adhesives for composite bonding ARALDITE offers a number of epoxy based solutions which combine high strength, with creep, chemical and fatigue resistance and also flame retardant capabilities.

ARALDITE 2033 is a two component gap-filling epoxy ad hesive with flame retardant properties that has surpassed the HL3 hazard level of fire safety testing under the rigorous unified Pan-European EN 45545-2 testing regime.
Classified in the combined R22 Interior and R23 Exterior category, it meets all requirements to achieve the HL3 level, with test parameters that include for instance, evaluation of spread of flame, ignitability, or smoke and toxic gas emissions.

New structural adhesives Araldite

Two-component, toughened, methacrylate adhesive systems replace Araldite 2021 and Araldite 2022 respectively, with the new products offering measurable improvements.

Other features of Araldite 2021-1 and Araldite 2022-1 include:

• Improved elongation at break;
• Notable toughness and resilience to vibrations;
• Dynamic loading;
• Mechanical impact and assembly of dissimilar substrates.

With both products offering non-sagging and gap-filling properties, they enable easy processing and make vertical applications possible.
Following on from stringent testing Araldite 2021-1 and Araldite 2022-1 deliver good lap shear strength across a variety of substrates and a wide range of temperatures.
Araldite 2021-1 and Araldite 2022-1 also offer temperature resistance of up to 100°C and tolerance of non-ideal surfaces, which enables easier processing and, therefore, increased productivity.
