Supex 620 High Temperature Adhesive | Heat Resistant Glue up to 210°C | India

Meet Supex 620 – Your Reliable High Temperature Adhesive

You face extreme heat in your projects. Supex 620 handles it perfectly. This one-component MS Polymer high temperature adhesive bonds strongly. It resists heat, weather, and UV. Moreover, it works up to 210°C intermittently. Industries in India choose it for tough conditions. Therefore, it becomes the top heat resistant glue for metal.

First, note its key strength. Supex 620 stays flexible after curing. It forms permanent bonds under stress. Additionally, it avoids shrinkage. This ensures long-lasting results.

Key Features of Supex 620 Heat Resistant Glue

Supex 620 excels as a high temperature adhesive. Check these features:

• One-component MS Polymer – Easy to use, no mixing needed.
• Solvent-free, silicone-free, isocyanate-free – Safer for users and eco-friendly.
• High heat resistance – Intermittent up to 210°C; survives powder coating heat cycles.
• Strong adhesion – Bonds without primer on many surfaces.
• Flexible and durable – Absorbs movement and vibrations.
• No staining – Safe for natural stone and sensitive materials.
• UV and weather resistant – Performs in harsh outdoor conditions.
• Abrasion resistant – Handles foot traffic and wear.
• Works on damp surfaces – Applies even underwater.
• Low dirt pick-up – Stays cleaner longer.

Furthermore, paints adhere easily over it. This adds versatility.

Applications in Automotive, Industrial & Marine – high temperature adhesive

Supex 620 is a premium high temperature MS Polymer adhesive (heat resistant up to 210°C intermittent), solvent-free, flexible, and primerless. It excels in demanding environments with vibration, weather, UV, abrasion, and thermal cycling—making it ideal for these sectors in India and beyond.

Automotive Applications

Supex 620 bonds parts exposed to engine heat and high temperatures, where traditional adhesives fail.

• Bonding metal components in engine bays, exhaust areas, or under-hood assemblies.
• Securing heat shields, brackets, or panels that endure thermal stress and vibrations.
• Replacing mechanical fasteners (screws/rivets) in high-heat zones for stronger, flexible joints that resist cracking or loosening. Its ability to survive powder coating cycles adds value in automotive manufacturing and aftermarket repairs.

Industrial Applications

Perfect for assembling and maintaining equipment in hot or dynamic settings.

• Bonding in machinery, ovens, boilers, or production lines with elevated temperatures.
• High-stress dynamic joints in manufacturing plants, heavy equipment, or fabrication shops.
• Metal-to-metal, metal-to-rubber/plastic/composite bonding where heat, abrasion, and movement occur. It provides durable, vibration-absorbing bonds without shrinkage, ideal for industrial environments requiring long-term reliability.

Marine Applications

Supex 620 secures components against harsh weather, salt spray, moisture, and UV exposure.

• Bonding and sealing fittings, hardware, or panels on boats, ships, or offshore structures.
• Applications in damp/wet conditions (applies to wet surfaces) for hull repairs, deck fittings, or marine equipment.
• Flexible seals that withstand saltwater corrosion and constant movement/vibration. Its weather/abrasion resistance ensures performance in marine demanding environments.

Why Supex 620 Stands Out

• Strong, permanent, elastic bonds on metals (stainless steel, aluminum), rubber, plastics, glass, concrete, wood, etc.
• No primer needed, eco-friendly (no solvents/isocyanates/silicones), paintable, and non-staining.
• Handles intermittent 210°C heat while staying flexible—better than rigid alternatives in vibrating/high-stress uses.

How to Apply Supex High Temperature Adhesive

Apply it easily. Follow these steps:

1. Clean surfaces well. Remove dust, oil, or grease.
2. Cut the cartridge tip. Load into a caulking gun.
3. Apply evenly in beads or as needed.
4. Press surfaces together quickly.
5. Let it cure. It skins over fast and fully cures over time.

It works on wet surfaces. This saves time in real-world jobs. For cleanup, use appropriate solvents before curing.

FAQs for Supex 620 – High Temperature MS Polymer Adhesive

1. What is the maximum temperature resistance of Supex 620?

It handles intermittent temperatures up to 210°C (e.g., survives powder coating cycles or engine bay heat). Continuous exposure may be lower—consult for specific use cases. It’s more heat-resistant than standard MS Polymers (typically 120–150°C) but flexible unlike rigid high-temp alternatives.

2. Which materials can Supex 620 bond to?

It bonds without primer to a wide range: metals (stainless steel, aluminum, copper), rubber, plastics, composites, glass, concrete, wood, and more. Excellent for metal-to-metal, metal-to-rubber, or mixed substrates in automotive, industrial, and marine settings.

3. Does Supex 620 work on wet or damp surfaces? Yes! It applies and bonds effectively on wet/damp surfaces—even underwater in some cases—making it ideal for marine repairs, outdoor industrial use, or humid Mumbai conditions.

4. What is the curing time for Supex 620?

It skins over quickly (fast skin formation). Full cure depends on humidity, temperature, and bead thickness—typically advances at 2–3 mm per day in standard conditions (similar to other MS Polymers). Higher humidity speeds it up; cold/dry slows it.

5. Is Supex 620 eco-friendly and safe?

Yes—solvent-free, no isocyanates, no silicones. Low VOC, REACH-compliant, and eco-friendly. It’s paintable, non-staining (won’t mark natural stone), and low dirt pick-up. Always refer to the MSDS for safe handling.

6. Can Supex 620 replace mechanical fasteners? Absolutely—in high-stress, vibrating, or high-heat joints (e.g., automotive brackets, engine parts, industrial machinery). It absorbs movement, prevents cracking/loosening, and provides durable, elastic bonds.

7. Why choose Supex 620 over silicone or other adhesives?

Unlike silicones (which may not bond as strongly to some metals or allow painting easily), Supex 620 offers better flexibility, primerless adhesion, no shrinkage, and superior performance in dynamic/high-vibration applications while handling high intermittent heat.
