Araldite 2028-1: High-Performance Transparent Polyurethane Structural Adhesive for Demanding Bonding Needs
Structural adhesives are the "unsung heroes" of modern manufacturing, playing a critical role in joining diverse materials like metals, plastics, and ceramics. Compared to traditional welding or riveting, adhesive bonding enables more uniform stress distribution, avoids thermal deformation, and does not damage material surfaces.
Huntsman Advanced Materials, with its renowned Araldite brand, is a leader in the field of structural adhesives. Its product, Araldite 2028-1, is an outstanding example designed for high-demand applications.
Outstanding Product Characteristics
Araldite 2028-1 is a two-component, transparent polyurethane adhesive that combines excellent mechanical properties with aesthetics.
High Transparency & Aesthetics: The cured adhesive is transparent, making it ideal for applications where maintaining product appearance or achieving light transmission is crucial, such as in assembling glass products or transparent plastic components.
Fast Curing & High Strength: This product features rapid curing, significantly shortening production cycles. It delivers high final bond strength with excellent peel and impact resistance. According to the TDS, after curing for 16 hours at 40°C, it achieves excellent typical lap shear strength on aluminum alloys, maintaining stable performance even at elevated temperatures and under harsh conditions.
Excellent Durability: Araldite 2028-1 offers superior resistance to UV aging, damp heat (e.g., simulated tropical weathering), and heat aging. It also demonstrates good resistance to a range of common chemicals, ensuring the long-term reliability of the bonded joint.
Broad Substrate Compatibility: It is suitable for bonding a wide range of metals (e.g., aluminum, steel) and plastic substrates, providing strong bonds for both similar and dissimilar materials.
Convenient Processing & Storage
Araldite 2028-1 is supplied in cartridges with integrated static mixers. It can be directly applied using recommended dispensing equipment, ensuring precise metering and homogeneous mixing, which simplifies the process and is ideal for automated production. For optimal bonding, proper surface pretreatment (e.g., degreasing with acetone or iso-propanol) is recommended.
The product should be stored in a cool, dry place at 15-25°C. The expiry date for unopened containers is indicated on the label. After opening, use promptly and ensure proper sealing if not fully used.
Real-World Application Scenarios
hanks to its transparency, strength, and durability, Araldite 2028-1 finds applications in various industries:
Transportation: Bonding transparent plastic interior panels, signage in buses or trucks, and assembly of certain vehicle components, offering both strength and a clean appearance.
Electronics & Electrical: Used in applications requiring transparent potting or securing internal transparent components, providing structural support without obstructing visual inspection or light paths.
Sports Equipment & Security Devices: Bonding composites and transparent viewing windows in high-performance sports equipment, or assembling housings for security devices, ensuring ruggedness in diverse environments.
