FieldsMaster PU Binder Tensile Test: Comparing 5 Models

The honest truth? There is no single "best" glue—there is only the right glue for your specific project. Choosing a binder based purely on price or abstract marketing claims often leads to project failures. To take the guesswork out of your sourcing, we put 5 of our main FieldsMaster PU Binders through a rigorous, ultimate tensile lab test in April 2026.

Let' s skip the heavy chemical jargon. Here is a down-to-earth guide based on real data to help you choose exactly what you need:

In industrial adhesives, Max Force indicates the absolute load-bearing limit, while Elongation at Break tells you how well the material can handle temperature shifts and physical deformation without cracking.

Here is how our 5 models performed:

What it means for you: This is the heavyweight champion. If your project demands extreme bonding strength and maximum load-bearing capacity, this is your blind-buy choice. It broke the charts in our test with zero compromises on strength.

What it means for you: Not only does it hold over 100N of force, but it stretches almost 80% before snapping! If you are building in areas with extreme temperature shifts or where the base structure might shift, this binder absorbs the stress to prevent surface cracking. It bends without breaking.

What it means for you: High strength, minimal stretch. This formula is designed for projects where you need a firm, stiff hold. When you absolutely cannot afford any structural deformation or shifting, this is your shield.

What it means for you: You don't always need a sledgehammer to crack a nut. For the vast majority of standard, everyday installations, these two models offer the perfect balance of solid performance and cost-efficiency. They exceed standard requirements and are your reliable daily drivers.
