ARALDITE® 2015-2: the new structural epoxy adhesive for more durable and safer assemblies
In industry, bonding is no longer just a simple joining function. It has become a genuine design, durability and overall performance issue. Today, choosing an epoxy adhesive is no longer just about comparing mechanical strength values on a datasheet. Manufacturers are looking for solutions that can deliver excellent in-service performance, integrate into real production conditions, withstand demanding environments and, increasingly, meet stricter HSE requirements.
ARALDITE® 2015-2 fully reflects this product range evolution. Developed by Huntsman, it is the non-CMR reformulation of ARALDITE® 2015-1, extending a product already widely recognized on the market. With this new generation of epoxy adhesives, Huntsman is evolving its bonding solutions to respond more accurately to today’s market expectations, combining mechanical robustness, operator safety, regulatory compliance and industrial performance.
At Samaro, we believe ARALDITE® 2015-2 deserves special attention because it brings together five key messages that are especially relevant for today’s manufacturers:
- a new generation of epoxy adhesive (not subject to CMR classification and formulated with no intentionally added BPA)
- three major technical benefits (resistance to dynamic loads, thixotropic behaviour, reinforced formulation)
- easy to apply (1:1 ratio)
- packaging in recycled plastic cartridges with no change to the process

A new generation of epoxy adhesives
ARALDITE® 2015-2 belongs to a new generation of epoxy adhesives. Beyond technical performance, this evolution also reflects a strong market expectation for solutions that are better aligned with safety, compliance and HSE requirements.
It is in this context that ARALDITE® 2015-2 was formulated with no intentionally added BPA and is not subject to CMR classification. Today, an epoxy adhesive is no longer selected solely for its mechanical performance. Conditions of use, regulatory requirements and the long-term relevance of technical choices matter just as much.
With ARALDITE® 2015-2, Huntsman is evolving its range to meet these new expectations by offering a solution that combines robustness, compliance and stronger alignment with current industrial standards.
Designed for durable assemblies. Developed for operator safety.
The product promise can be summed up in one particularly strong sentence:
Designed for durable assemblies. Developed for operator safety.
This signature gives an immediate understanding of the product. It expresses two complementary objectives.
The first is bond durability. ARALDITE® 2015-2 was designed to create reliable, robust and long-lasting joints, including when bonded parts are exposed to real operating stresses.
The second is consideration for safety at the workstation. In an industrial context where HSE expectations continue to rise, this dimension has become essential. It does not replace technical performance; it complements it.
This promise can be effectively summarized in the following three-part message:
Safe
The product fits more coherently with today’s HSE challenges.
Strong
This structural epoxy adhesive is designed to deliver a high level of performance for demanding technical assemblies.
Compliant
It responds to evolving regulatory and industrial expectations, which are now central in the selection of bonding solutions.
Three technical advantages that truly make the difference
ARALDITE® 2015-2 stands out through three major technical advantages: its resistance to dynamic loads, its high gap-filling capacity and its reinforced formulation.
Resistance to dynamic loads
In many industrial applications, assemblies are exposed to vibrations, impacts or repeated stresses. ARALDITE® 2015-2 was developed to perform well under these conditions.
This is a major advantage for parts subjected to real in-service stresses, particularly in transport, rail, composite structures and certain industrial equipment.
High gap-filling capacity
In production, parts are not always perfectly fitted. ARALDITE® 2015-2 offers real flexibility here thanks to its thixotropic viscosity and its ability not to sag up to 10 mm thickness.
This property makes it easier to accommodate assembly gaps, surface irregularities and certain manufacturing tolerances, while maintaining a stable and clean application.
Reinforced formulation
Its reinforced formulation provides a better balance between mechanical strength, toughness and long-term durability.
This is especially valuable for assemblies exposed to complex stresses or for bonding materials that do not behave in exactly the same way mechanically.
A few typical application examples
ARALDITE® 2015-2 targets applications where bond quality plays a direct role in the overall reliability of the assembly.
Metal and composite parts
This combination of materials is increasingly common. It makes it possible to reduce weight, improve the distribution of mechanical functions, integrate multi-material solutions and optimize certain subassemblies. But it also requires an epoxy adhesive capable of handling substrates with different behaviours.
ARALDITE® 2015-2 fits this logic particularly well. Its resistance to dynamic loads, gap-filling capacity and reinforced formulation make it a highly relevant epoxy adhesive for metals and composites, especially for:
- metal/composite interfaces
- reinforcements
- panels
- technical subassemblies
- certain structural parts
Composite structures in demanding environments
ARALDITE® 2015-2 is also suitable for composite structures exposed to demanding conditions: humidity, vibrations, repeated stress or climatic variations. This makes it especially relevant for marine applications, transport, energy and various industrial composite applications.
Rail: train door assemblies
The rail sector imposes very high requirements. Assemblies must be reliable, repeatable, durable and capable of withstanding numerous operating cycles. When an epoxy adhesive proves relevant in this type of application, it says a great deal about its level of technical maturity.
ARALDITE® 2015-2 finds a highly representative application here: technical subassemblies exposed to significant mechanical and functional stresses, with a strong requirement for long-term bond stability.
Recycled plastic cartridges to reduce carbon footprint
ARALDITE® 2015-2 is supplied in recycled plastic cartridges, with CO₂ emissions reduced by up to 36%.
This point deserves to be highlighted, because it shows that innovation is not limited to formulation alone. It also extends to packaging and to the product’s overall environmental footprint. This is a positive signal for manufacturers looking to improve their practices without adding complexity to their operations.
