HARDENER HY 5049
Harmonization Code : 8529.90 | Parts solely or principally used for TV, radio, and transmission
Main features
- High-Strength Structural Bonding
- Documented Water/Ice/Tropical-Climate Resistance
- Transparent Cured Bondline
Product Description
ARALDITE® 5049 A/B is a two-part epoxy laminating adhesive that cures to a transparent bondline, making it highly suitable for fabricating composite parts such as snow skis and snowboards. This system requires a heat cure for optimal results and is engineered to bond effectively to a wide variety of materials commonly used in the ski industry.
Key features
- High structural integrity: Formulated to deliver high strength under both static and dynamic loading conditions.
- Environmental durability: Provides robust resistance to challenging outdoor conditions, including water, ice, and tropical climates.
- Aesthetic finish: Creates a transparent bondline that preserves the visual quality of laminated recreational equipment.
Applications / Suitable for
- Laminating snow skis and snowboards.
- Fabricating composite archery limbs.
- Bonding honeycomb core facing.
