Best Sandwich Panel Adhesive India | Supex 8104 2-Part PU Glue

Discover Supex 8104 – The Top Choice for Sandwich Panel Bonding

You need a reliable adhesive for sandwich panels. Supex 8104 delivers exactly that. This solvent-free two-part PU adhesive creates strong, durable bonds. Manufacturers in India trust it for vehicles, containers, construction, and marine projects. Moreover, it bonds pretreated metals, wood, hard foams, synthetics, and more without issues.

First, understand why sandwich panel adhesive matters. These panels combine insulation cores (like foam or Rockwool) with metal sheets. A weak bond fails over time. However, Supex 8104 prevents that. It offers high shear strength and no foaming. Therefore, you get clean, professional results every time.

Key Features of Supex 8104 2-Part PU Adhesive

Supex 8104 stands out among sandwich panel adhesives. Here are its main strengths:

• Solvent-free formula – Safe for workers and the environment.
• Two-component system – Mix polyol resin (main agent) with isocyanate (curing agent) at 100:25 ratio by weight.
• No foaming at 25°C – Ensures even application and strong contact.
• High strength – Tensile shear strength ≥6 MPa on aluminum; plane tensile strength ≥0.1 MPa for inorganic boards to Rockwool.
• Wide temperature resistance – Works from -40°C to 70°C.
• Fast pot life – 20-30 minutes at 25°C for easy handling.
• Adjustable dosage – Apply 250-500 g/m² based on materials.

Additionally, it resists moisture during curing. This feature boosts long-term durability. Many competitors foam or weaken in tough conditions. Supex 8104 avoids those problems.

Why Choose a 2-Part PU Adhesive Like Supex 8104?

Two-part polyurethane adhesives outperform one-part options in many ways. For example, they cure reliably without relying on air moisture. This makes them ideal for thick bonds or enclosed panels. In contrast, one-part adhesives can cure unevenly.

Supex 8104 excels in structural bonding. It fills gaps well and maintains flexibility. As a result, panels handle vibrations, temperature changes, and loads better. Industries in India prefer it for refrigerated trucks, cold rooms, and building facades. Furthermore, it meets eco-friendly standards with low or zero VOCs.

Common Applications of Sandwich Panel Adhesive

Use Supex 8104 for various projects:

• Vehicle manufacturing – Bond panels for trucks and trailers.
• Container production – Create insulated shipping units.
• Construction – Build walls, roofs, and clean rooms.
• Marine industry – Assemble durable structures on boats.
• Other uses – Potting, filling, or coating compounds.

It bonds metals to foams, wood to synthetics, or Rockwool to sheets. Therefore, versatility saves time and inventory costs.

How to Apply Supex 8104 Effectively

Application is simple and straightforward. Follow these steps:

1. Clean surfaces thoroughly. Remove dust, grease, and moisture.
2. Mix the two parts at 100:25 ratio. Stir evenly for uniform results.
3. Apply with a serrated scraper, roller, or two-component machine.
4. Press layers together during curing. This ensures tight contact.
5. Allow initial bonding in 4-6 hours at 25°C. Full cure takes 7 days.

For uncured glue, use Supex cleaner. Remove cured adhesive mechanically. Always store at 10-30°C and avoid moisture for a 6-month shelf life.
