Product Description
ARALDITE® 5049 A/B Adhesive is a two-part epoxy laminating system for composite assemblies, including ski and snowboard laminates, archery limbs, and honeycomb core facing. The mixed material has a typical viscosity of 2,800 cP at 25°C and is normally applied as a 0.05-0.10 mm bondline. It cures to a transparent bondline, with heat cure recommended for optimal results; typical cure options range from 60-120 minutes at 60°C to 15-20 minutes at 100°C. The cured adhesive combines documented strength under static and dynamic loading with resistance to water, ice, and tropical conditions. A typical 75-minute gel time at 25°C for a 100 g mass supports controlled positioning during lamination and assembly.
Key features
- Lamination strength: Documented high strength under static and dynamic loading for composite bonding applications.
- Controlled heat cure: A 75-minute gel time at 25°C and cure cycles from 60°C to 100°C support process selection.
- Environmental resistance: Good resistance to water, ice, and tropical conditions.
Applications / Suitable for
- Ski and snowboard lamination
- Archery limb lamination
- Honeycomb core facing

Store ARALDITE AY 557 Resin and Hardener HY 5049 in a dry place in their original sealed containers at 2-40°C, protected from direct sunlight. Under these conditions, shelf life is 3 years from the date of manufacture. Material stored below 15.6°C should be conditioned at approximately 15.6-25°C before use.
Typical mechanical and thermal properties
Typical laboratory values only. Unless otherwise stated, standard specimens were tested at 25°C and cured for 7 days at 25°C. The Tg value uses the cure condition stated in its row.
