Elastic Polyurethane Resin with High Elongation for Impact Absorption

What Does High Elongation at Break Mean?

Elongation at break is a measurement of how much a material can stretch before it breaks. A polyurethane resin with high elongation can bend and withstand deformation under stress, making it especially suitable for absorbing shocks and resisting cracking or delamination.

This property is particularly valued for protective surfaces exposed to frequent impacts or vibrations, such as motorcycle tanks, trays, or furniture tops.

Practical Application and Guidance

For those looking to utilise a flexible, impact-resistant resin, surface compatibility and project scale are key considerations. For small to medium projects—such as custom trays or decorative elements—the Heat Pro flexible coating offers a combination of elastic protection and a glossy finish. It’s important to apply the resin on a clean, dry, and stable surface, allowing for full curing to maximise impact absorption.

• Follow the recommended mixing ratio for your chosen resin.
• Make sure each layer is fully dry before adding the next.
• Do not apply flexible polyurethane on surfaces that require rigid, load-bearing characteristics.

When Does High Elasticity Matter Most?

Opting for resin with high elongation at break is especially beneficial where protection from knocks, drops, or frequent movement is required. Examples include decorative trays, protective table finishes, or vehicle areas at risk of scratching and denting. For larger, more intense traffic surfaces, a robust product like Prolux PU coating may be a better fit, as it combines elasticity with enhanced resistance to abrasion and UV exposure.
