FAQs – best MMA adhesive for metal bonding

1. What is the best mma adhesive for metal bonding?

Supex 3090 stands out as the best adhesive for metal bonding in India. This high-strength 2-part MMA structural glue delivers unbreakable, durable metal-to-metal bonds without welding or primers. Ideal for aluminum, steel, and more, it offers excellent impact resistance, toughness, and long-term reliability for industrial use.

2. How to bond metal without welding?

Bond metal without welding using Supex 3090, a high-strength MMA structural adhesive. Clean and roughen surfaces, apply via dual-cartridge gun with mixer nozzle, clamp parts (gap up to 9mm), and cure (fixtures in ~90 min). Delivers durable, weld-like bonds for steel, aluminum & more—no heat or distortion.

3. Supex 3090 vs epoxy for metal?

Supex 3090 (MMA structural adhesive) outperforms typical epoxies for metal bonding in versatility, requiring minimal/no surface prep or primers, offering superior impact/toughness resistance, and bonding metals to plastics/composites easily. While epoxies may provide slightly higher peak tensile strength in ideal conditions, Supex 3090 delivers faster fixture (~90 min), better durability under vibration/shock, and weld-like performance without heat/distortion.

4, Is MMA adhesive suitable for underwater bonding?

Standard MMA adhesives (methyl methacrylate structural adhesives) like Supex 3090 are not typically designed or recommended for direct underwater application or bonding while fully submerged. They excel in humid, wet, or marine environments once cured, but the mixing and initial curing process usually requires dry or controlled conditions

Usage instructions

How to Use Supex 3090 – Step-by-Step Guide

Supex 3090 is a two-part (1:1 mix ratio) methyl methacrylate (MMA) structural adhesive supplied in dual cartridges (e.g., 400 ml). It offers a long 30–40 minute working time, making it ideal for precise alignment on large or complex parts. Follow these steps for best results. Always refer to the full TDS and safety data sheet (MSDS) for your specific cartridge.

1. Preparation and Safety

Work in a well-ventilated area at 18–30°C (optimal: 18–28°C). Avoid below 15°C, as cure slows significantly.
Wear nitrile gloves, safety glasses, and protective clothing. MMA adhesives can irritate skin and eyes.
Keep away from sparks, flames, and heat sources (flammable components).
Clean substrates: Remove dust, oil, grease, or loose particles. Minimal surface prep is often enough (e.g., wipe with isopropyl alcohol). For best strength on metals, lightly abrade if needed.
Ensure parts fit well (gap up to 9 mm is OK).

2. Cartridge Setup

Use a compatible dual-cartridge gun (manual or pneumatic) for 1:1 cartridges.
Remove the cartridge cap or retaining nut.
Attach a static mixing nozzle (recommended: 10–24 elements, similar to 10 mm ID with sufficient mixing stages for uniform blend).
“Burp” or purge: Squeeze the gun trigger a few times (3–5) to fill the mixer and remove air. Discard the first 10–20 cm of dispensed adhesive (mixed material) to ensure even color and proper ratio.

3. Mixing and Dispensing

Align Part A (off-white) and Part B (dark grey) in the gun.
Apply steady pressure to dispense the adhesive through the static mixer.
The mixed adhesive should appear uniform in color (no streaks) before use—this confirms good mixing.
Dispense directly onto one substrate or into the joint. Apply in beads, zig-zag, or full coverage depending on the area.
Work quickly but within the 30–40 minute open time (at ~23°C). Higher temps shorten this; lower temps extend it but may affect cure quality.

4. Assembly and Clamping

Bring parts together within the working time.
Apply firm, even pressure to close the gap and squeeze out excess (avoid excessive force that starves the joint).
Clamp or fixture if needed to maintain position during fixture (90–100 minutes to handling strength at room temp).
Avoid disturbing the bond during early cure.

5. Cure and Cleanup

Full cure develops over 24 hours (strength builds progressively).
Fixture strength reaches handling levels in ~90–100 min; full structural strength in 24 h.
Clean uncured adhesive with acetone or appropriate solvent immediately (wear gloves).
Cured excess can be removed mechanically (e.g., scraping).

Key Tips for Success

Do not mix large volumes manually—use cartridge system to avoid exotherm issues (heat buildup can cause cracking/voids in big masses).
Test on scraps first for your substrates (e.g., metals, PA66 nylon, PVC, carbon fiber).
Avoid oxygen-rich environments if possible (though less sensitive than some MMAs).
Store cartridges at 13–25°C (cooler extends shelf life to 12+ months). Avoid >38°C.

This adhesive excels in automotive, marine, construction, and composite bonding due to its toughness and gap-filling. For exact specs or troubleshooting, check the official TDS.
