Whether on schoolyards, multipurpose courts, or international sports facilities, CONIPUR 322 is widely used around the world and is considered a true benchmark when it comes to processing rubber granules into elastic base layers.

The foundation for peak athletic performance

CONIPUR 322 is a moisture-curing, solvent-free, single-component PUR binder based on MDI/TDI – specially developed for installing elastic granule mats in sports facility construction. It features a well-balanced viscosity that makes the material easy to work with, prevents it from seeping into the subbase, and makes it ideally suited for use with recycled rubber granules. The result is a homogeneous, resilient, and long-lasting elastic layer that serves as a reliable base for various sports flooring systems – from structured spray coatings to cast surfaces.

Application with a time advantage

A particular highlight is CONIPUR 322’s applicator-friendly processing time. Even after several hours, seams can still be smoothed out with ease – a clear advantage on-site, especially when working on large surface areas.

Its excellent mixability with rubber granules allows for efficient work without compromising on quality. The viscosity is precisely adjusted to ensure the binder adheres well to the granules and doesn’t seep into the subbase.

Recycling meets performance

Another benefit: CONIPUR 322 is optimally designed for use with recycled rubber granules – a material that is not only economically attractive for many projects but also scores points in terms of resource conservation.

This is a persuasive argument, particularly for public tenders or sustainable construction projects, convincing planners, municipalities, and developers alike. And: the mechanical properties of the finished sports surfaces naturally meet the requirements of established standards such as EN 14877 – provided the recommended quantities and granule sizes are followed.

Proven and trusted – used worldwide

CONIPUR 322 stands for long-term experience, processing stability, and reliability. In use, it proves resistant to environmental influences, easy to handle, and dependable in its results. Yellowing due to UV exposure can occur with certain granule colors – blue granules may take on a greenish hue, while grey ones may appear yellowish. To prevent this, we recommend using our UV-stable binders – though the mechanical properties of CONIPUR 322 remain unaffected by discoloration.

Conclusion: The solid foundation for modern sports flooring

Whether for new builds or refurbishments, municipal projects or international sports arenas – with CONIPUR 322, contractors, planners, and facility operators choose a binder that impresses with its quality, flexibility, and durability – and one that has proven its worth in countless projects worldwide.
