ACRI-BOND AB290 Clear Acrylic Structural Adhesive

ACRI-BOND AB290 is a clear plastic bonding 2 Part Methyl Methacrylate Adhesive (MMA). It has a very strong bond to most plastics and in most cases the substate will break before the bond. Due to its crystal-clear appearance, it is very versatile making it suitable for clear thermoplastics like acrylic and polycarbonate. ACRI-BOND AB290 is perfect for aquarium building, structural plastic bonding, sign fabrication, filling cracks and plastic fabrication that requires a strong bond or sealing.

Product Overview

ACRI-BOND AB290 is a crystal clear two-part Methyl Methacrylate Adhesive (MMA) designed for high-strength structural bonding of plastics and other rigid substrates. Engineered for clarity, versatility, and uncompromising performance, ACRI-BOND AB290 is ideal for professional plastic fabricators, sign makers, aquarium builders, and repair specialists looking for a reliable adhesive that delivers strength, impact resistance and aesthetics.

What sets ACRI-BOND AB290 apart is its perfectly clear finish, making it the go-to solution when appearance matters just as much as bond strength. Whether you are bonding clear acrylic, clear polycarbonate, or sealing decorative plastic components, this adhesive remains virtually invisible once cured, providing a seamless result.

An immense advantage of methacrylate adhesives is their ability to reach handling or working strength within minutes of application. While full cure typically takes 24 to 48 hours, most formulations develop enough strength in the early stages to allow for clamping removal, light assembly movement, or downstream processing. This rapid strength build-up is especially valuable in production environments where reducing wait times can significantly increase output and efficiency. It also means parts can be moved, drilled, or machined sooner, without waiting for a full cure, helping to streamline workflows without sacrificing bond integrity.

With an impressive bond strength that often exceeds the substrate itself, ACRI-BOND AB290 delivers unmatched performance across a wide range of plastics. It excels on acrylic (PMMA), polycarbonate (PC), ABS, and PVC. It also performs well on composites and natural materials including fibreglass (FRP), carbon fibre, MDF, and wood.

Applications and Uses

Materials Bonded

Acri-Bond 290 bonds to a variety of plastics including: Acrylic (PMMA), Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), Polyvinyl Chloride (PVC)

It has also shown great results with bonding: Fibreglass Reinforced Plastic (FRP), Carbon Fibre (CF), Wood, MDF

ACRI-BOND AB290 will not adhere to plastics with a low surface energy such as Polypropylene (PP), Polyethylene (PE) or Polyolefins. These plastics can be structurally adhered to with NEXTITE AB206 and NEXTITE Cyanoacrylates also have a great bond when using NEXTITE SP901 Primer.

Applications

Acrylic Fabrication, Acrylic Aquarium Fabrication, PVC Pipe Cladding Sealant, Repairing Plastic Parts, Automotive Plastics, FRP / CF Repair and Fill, Acrylic Double Glazing, Boat Repairs, Permanently Laminating Dissimilar Materials, Filling Hardwood Holes.

Versatility

While bond strength is important, it’s not the only factor to consider when selecting an adhesive. Once fully cured, Acri-Bond 290 delivers a range of additional benefits that can make a real difference depending on your application.

-        When fully cured Acri-Bond 290 can be sanded, grinded, routed and polished to get your desired finish. You can even paint over it!

-        Great Chemical Resistance

-        High resistance to weathering, will not yellow like other products available

-        Can be used in indoor and outdoor applications

-        Waterproofing when applied correctly

-        High Temperature resistance -40 to 140°C

Tools and Accessories

ACRI-BOND AB290 requires the use of a compatible dual cartridge dispensing applicator and static mixer nozzles, sold separately. Both the 50mL and 250mL Cartridges use standard 10:1 Ratio dual cartridge dispensing applicators and static mixers. It is important to use the correct applicator and mixer for each cartridge size, as 10:1 ratio systems are not compatible with other ratios cartridges and accessories. Each cartridge type requires the matching dispensing applicator and static mixer designed specifically for its ratio.

50mL Tubes

Dispensing Applicator: Manual 50mL 10:1 Dispensing Applicator | Manual Hand Plunger for 10:1 50mL Cartridges (for one time use)

Static Mixer Nozzles: 10:1 50mL Quadro B Type (Standard Tip) | 10:1 50mL Quadro B Type (Narrow Tip)

250mL Tubes

Dispensing Applicator: Manual 250mL 1:1 Dispensing Applicator

Extra Static Mixer Nozzles: 1:1 250mL F Type (Orange – Orange Base)

Technical Highlights

Instructions for use

1.     Use a static mixer nozzle to accurately mix the contents of the 10:1 cartridge. Each cartridge includes one Static Mixer Nozzle Orange 10:1, and you can purchase more in 5, 10 and 50 packs from our store.

2.     You will also require a 10:1 Static Mixing Dispenser to push the contents through the static mixer. This is the best way to apply it and get accurate, dependable results every time.

3.     Parts to be joined should fit without forcing and be clean, it is recommended to use NEXTITE PROPREP or ACRI-BOND CLEANER (for delicate materials) prior to applying any product to remove any oils, dust and dirt. It is important to let out any air bubbles and ensure adhesive is fully mixed by dispensing the first part of the cartridge onto some paper. This is to make sure the two separate parts are fully mixed and is generally the first 2-3mL. Apply adhesive directly from the static mixer.

4.     Press parts together in firm contact and use a clamp to secure while the glue reacts. ACRI-BOND AB290 will achieve a working strength within 16-20 min and full cure strength within 24 hours. You have approximately 6-8 minutes to work with the glue before it starts to set off.

Please check the TDS for material suitability and strength of each bond. For a tutorial how to use please refer to our YouTube Chanel.
