ARALDITE® 2013-2: Next-generation “non-CMR” structural epoxy paste

Samaro presents ARALDITE® 2013-2, the “non-CMR” reformulation of ARALDITE® 2013-1: a 2-component paste epoxy, thixotropic, high-strength, and non-sag adhesive for structural bonding of metals and many other substrates (ceramics, glass, rubbers, rigid plastics). Cures at room temperature with chemical and environmental resistance and robust performance.

2013-2: Continuity of performance, modernized HSE profile

ARALDITE® 2013-2 joins Huntsman’s 2025 wave of epoxies with no intentionally added CMR substances and BPA-free, with a clear goal: preserve the performance DNA of 2013-1 while elevating the HSE profile.

What changes between ARALDITE® 2013-1 and 2013-2

HSE reformulation: transition to 2013-2 within Huntsman’s 2025 “non-CMR” strategy.
Usage & performance retained: thixotropic, non-sag paste; multi-material bonding; chemical/environmental resistance.
Comparable shop window to 2013-1: pot life ≈ 120 min; handling strength ≈ 10 h at 23 °C (on standard test specimens).

Benefits

Thixotropic / non-sag: clean beads with no slump, including fillets/thick sections.
Substrate versatility: metals (core target), plus ceramics, glass, rubbers, rigid plastics.
Comfortable processing: pot life ~120 min; handling strength ~10 h at 23 °C.
Durability: good chemical & environmental resistance; high mechanical strength.

Fiche d’identité – ARALDITE® 2013-2 Type :	2-part epoxy adhesive, thixotropic paste (non-sag)
Colour (mixed):	grey
Mix ratio:	1:1 (by weight & volume)
Pot-life (23 °C) :	≈ 120 min.
Handling / fixture time (23 °C):	≈ 10 h.
Shear strength (23 °C):	≈ 20 MPa Shear strength (23 °C):
Tensile strength (23 °C) :	≈ 36 MPa
Tg (Tan δ) :	≈ 64 °C (after 16 h / 40 °C)

“On metal-to-metal bonds and mixed assemblies, ARALDITE® 2013-2 is clean to work with: the thixotropic paste doesn’t slump, and the 120-minute window gives you time to align and clamp without stress. In production, the transition from 2013-1 required no change in routines.”

2013-2 in practice: what your operators will experience

Clean beads, no slump: neat application, including vertical joints up to a few millimetres.
Stress-free positioning: ~120 min to align, clamp and clean; ~10 h at 23 °C to handling strength.
Metal–metal & mixed assemblies: industrial bodywork, equipment, rail, aerospace (secondary parts), etc.

Surface prep: degrease (acetone/isopropyl alcohol), controlled abrasion (fine blasting on metals/composites), dust off, degrease again.

Metering & mixing: keep 1:1 ratio; mix thoroughly to full homogeneity; purge a few centimetres when using 2K cartridges.

Bead application: continuous beads with steady pressure; avoid entrapped air; recommended bond line for shear joints: 0.1–0.3 mm.

Curing: hold parts in position (clamping/fixturing) up to 1 MPa; strength build-up can be accelerated with a moderate post-cure (e.g., 16 h / 40 °C) as required.

Shear vs. temperature (ISO 4587): typical profile up to ~80–100 °C depending on cure conditions.
Chemical & humidity ageing: good performance after immersion and cataplasm (ISO 9142 E2).
Mechanical properties (23 °C, 16 h/40 °C): tensile strength ≈ 36 MPa, Shore D ≈ 75, compressive modulus ≈ 2.98 GPa (typical data).

Sectors & use cases

Transport / industrial bodywork: metal skins, stiffeners, accessories.
Rail & aerospace (secondary parts): metal/composite assemblies.
Equipment, energy & process: metal–plastic interfaces, demanding environments.
