Product Description
Araldite® 2028-1 structural adhesive is a two component, transparent, cold curing polyurethane adhesive that has a flash point of 212°F (100°C). It is fast curing and UV stable. It is suitable for bonding a variety of metal and plastic substrates.
Please Note: These cartridges are designed to work best with appropriately sized Dispensing dispensers. We advise you use the correct Dispenser to maximize efficiency and minimize waste. If you do not have one, please check out our Dispensers; all are excellent products and have our seal of approval.
If you prefer not to use a Dispenser, there is an option for a manual hand plunger or a caulking dispenser adapter that you can use for fast small jobs.
Features

- Easy to use 1:1 ratio packaging
Pretreatment
The strength and durability of a bonded joint are dependent on proper treatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone, isopropanol (for plastics) or other proprietary degreasing agents in order to remove all traces of oil, grease and dirt. Low-grade alcohol, gasoline, or paint thinners should never be used. The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces. Abrading should be followed by a second degreasing treatment.
Application of Adhesive
The resin/hardener mix may be applied manually or robotically to the pretreated and dry joint surfaces. Huntsman's technical support group can assist the user in the selection of a suitable application method as well as suggest a variety of reputable companies that manufacture and service adhesive dispensing equipment. A layer of adhesive 0.05 to 0.10 mm thick will normally impart the greatest lap shear strength to the joint. Huntsman stresses that proper adhesive joint design is also critical for a durable bond. The joint components should be assembled and secured in a fixed position as soon as the adhesive has been applied.

Product Name
- Araldite 2028-1 UV Stable Fast Setting Transparent Polyurethane (PUR) Adhesive
Brief Description
- Araldite 2028-1 is a two-component, fast-curing, UV-stable, and transparent polyurethane (PUR) structural adhesive.- It is specifically designed for applications requiring invisible bond lines, high strength, and excellent resistance to yellowing and environmental factors.- This adhesive cures at room temperature and is suitable for bonding a wide variety of metal and plastic substrates.
Popular Applications & Uses
- Bonding trim caps to polycarbonate in channel letters.- LED potting and light assembly, including clear encapsulation.- Traffic light and signage housing assembly.- Bonding transparent plastics, coated metals, and composites.- General bonding applications in signage, display assembly, and RV interiors.- Repair bonding, even at elevated ambient temperatures.- Structural bonding in vehicle manufacturing for enhanced strength and vibration resistance.- Sealing and bonding in automotive lighting systems.- Bonding insulation materials, flooring, and building components in construction.
Industries that Commonly Use It
- Sign & Display: For channel letters, digital signage, illuminated trim cap bonding, and advertising.- LED/Electronics: For LED potting, light assembly, and traffic light housing.- Plastic Fabrication: For bonding transparent plastics, polycarbonate, acrylics, PVC, ABS, PMMA.- Metal Fabrication: For bonding various metal substrates.- General Manufacturing: For diverse bonding requirements across various materials.- Automotive Service/Repair & Transportation/ Specialty Vehicle: For structural bonding, interior/exterior trim, and lighting systems.- Construction/ Building Services: For bonding insulation, flooring, building components, and cladding where transparency and UV stability are critical.- Marine: For boat building and outdoor applications due to its water resistance.- Artist, Artisan: For creative projects requiring clear, durable, and UV-stable bonds.- Distributers & Resellers: Companies that supply adhesives, tapes, and sealants to various manufacturers.
Special and Unique Features
- **Transparent:** Provides invisible bond lines, crucial for aesthetic applications.- **UV Stable:** Excellent resistance to yellowing and maintains appearance under UV, heat, and humidity stress.- **Fast Curing:** Offers a quick 6-8 minute working time (pot life) and 30-minute fixture time, supporting fast production cycles.- **Flexible and Impact-Resistant:** Provides flexibility and impact resistance after cure, with an elongation at break of approximately 60%.- **Two-Component System:** Consists of a resin and hardener, mixed in a 1:1 ratio for consistent performance.- **BPA-free and non-CMR formulation:** Enhances safety during use.- **Compatible with dispensing systems:** Ideal for robotic and manual dispensing setups using dual cartridge static mixing systems.
Key Properties
- **Chemistry:** Two-part polyurethane.- **Appearance (mixed):** Transparent.- **Working Time (Pot Life):** 6-8 minutes.- **Fixture Time:** 30 minutes.- **Full Cure:** Approximately 5 hours at room temperature.- **Lap Shear Strength:** > 8 MPa (Aluminum, 23°C).- **Tensile Strength:** ~2,320 psi (16 MPa).- **Tensile Modulus:** ~2 GPa.- **Elongation at Break:** ~60%.- **Shore Hardness:** Flexible.- **Temperature Resistance:** -40°C to +80°C.- **Specific Gravity:** 1.12.
Surface Compatibility
- Metals (e.g., aluminum, steel, stainless steel).- Plastics (e.g., ABS, PVC, polycarbonate, PMMA, acrylics, polyamides).- Glass.- Composites (e.g., fibre reinforced and thermoset composites, CFRP, SMC).- Wood.- Various rubbers.- Polystyrene foams and Polyurethane foams.
Known backups / known substitutes
- **Epoxy Adhesives:** Often used for structural bonding, though may differ in flexibility, cure time, and transparency.- **Methacrylate (MMA) Adhesives:** Another class of structural adhesives, known for fast curing and strong bonds.- **Loctite UK U-05FL:** A medium-viscosity urethane adhesive offering excellent peel and shear strength.- **Araldite 2028:** A similar two-component transparent polyurethane adhesive.- **Araldite AY 8629-1 w/ Hardener HY 8628:** Another 2-part polyurethane bonding system.- **Araldite 2029-1:** A two-component high-strength polyurethane adhesive for bonding metals.
Comparison Note
- Araldite 2028-1 stands out due to its specific combination of fast curing, exceptional UV stability (non-yellowing), and high transparency, making it ideal for applications where aesthetic appearance and outdoor durability are paramount.- While other polyurethane adhesives offer strong bonds and flexibility, Araldite 2028-1's clarity and UV resistance are key differentiators for clear bonding in exposed environments.- Compared to some epoxies, it offers greater flexibility and impact resistance, which can be beneficial for dissimilar substrates or dynamic loads.- Its fast fixture time allows for quicker handling compared to many other structural adhesives, enhancing production efficiency.
