NEXTITE AB204 Ultra Clear Methacrylate Structural Adhesive

Short Product Overview

NEXTITE AB204 is an ultra clear methacrylate adhesive that delivers high strength and dependable performance when bonding plastics, metals and composites with minimal surface preparation. It provides a high strength bond with a fast working time of 1-2 minutes, making it ideal for structural and general assembly applications that require an ultra clear appearance. The medium viscosity allows for easy, controlled application with slight flowability across a wide range of materials.

Product Overview

NEXTITE AB204 is an ultra clear, high-performance, two-part methyl methacrylate (MMA) structural adhesive engineered for demanding bonding applications. Designed for fast, reliable bonding of engineering plastics, metals, and composite materials, NEXTITE AB204 offers exceptional strength, durability, and ease of use.

With a fast working time of 1 to 2 minutes and fixture time of 4 - 5 minutes, this adhesive is perfect for production lines that need a fast cure and ultra clear adhesive. It allows for efficient assembly without the need for extensive surface preparation or primers. It is particularly suited for bonding thermoplastics, powder-coated metals, raw metals, and composite assemblies where high strength and impact resistance is critical.

NEXTITE AB204 delivers rapid strength development at room temperature, along with excellent toughness, fatigue resistance, and long-term durability. Its slightly flowable formulation allows for easy dispensing and superior wetting of close fitting joints without excessive run off. It also provides some gap filling capabilities of up to around 3mm. This adhesive is the go-to solution for industrial manufacturing, plastic fabrication, transportation, signage, general assembly and repairs where consistent performance, an ultra clear finish and structural integrity are required.

Applications and Uses

NEXTITE AB204 bonds to a variety of substrates they include but aren’t limited to:

• Plastics: Acrylic (PMMA), Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), Polyvinyl Chloride (PVC)
• Metals: Aluminium, Steel, Stainless Steel, Powder Coated Surfaces
• Composites: Fibreglass Reinforced Plastic (FRP), Carbon Fibre (CF)
• Other: Glass, Wood, MDF

NEXTITE AB204 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 SP 901 Primer.

Some applications of NEXTITE AB200 include:

• Signage and Displays: Perfect for channel letter / built up letter assembly and other display applications that require multi material bonding and an ultra clear adhesive
• Transport Industry: Used to bond plastics, composites or metals when adhesive bond-line could be visible.
• Marine: Used to bond plastics, composites or metals when adhesive bond-line could be visible.
  
• Industrial Equipment and Manufacturing: Used in machinery and appliance assembly for strong, impact- and vibration-resistant joints.
• Automotive: Bonding structural or cosmetic repair of automotive parts for example: headlight repairs, attaching or repairing trim pieces.

Versatility of NEXTITE AB204

While bond strength is important, it’s not the only factor to consider when selecting an adhesive. Once fully cured, NEXTITE AB204 delivers a range of additional benefits that can make a real difference depending on your application. 

• When fully cured NEXTITE AB204 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
• Can be used in indoor and outdoor applications
• Waterproofing when applied correctly
• High Temperature resistance -55 to 125°C

Tools and Accessories

NEXTITE AB204 requires the use of a compatible dual cartridge dispensing applicator and static mixer nozzles, sold separately. Both the 50mL and 400mL Cartridges use standard 1:1 Ratio dual cartridge dispensing applicators and static mixers. It is important to use the correct applicator and mixer for each cartridge size, as 1:1 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.

Instructions for use

1. Use a static mixer nozzle to accurately mix the contents of the 1:1 cartridge. Each cartridge includes one Static Mixer Nozzle Green 1:1, and you can purchase more in 5, 10 and 50 packs from our store.
2. You will also require a 1:1 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 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. NEXTITE AB204 will achieve a working strength within 3-5 min and full cure strength within 24 hours. You have approximately 1-2 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.
