| Résumé : |
A latent hardener has been designed to overcome multiple issues associated with the formulation of one-component polyurethane sealants.
Polyurethane (PU)-based joint sealants have become widely used for both new build and refurbishment projects, but their importance should never be underestimated, as they play an important role in the performance of a building throughout its lifetime. It might be a small detail, yet understanding the chemical makeup of polyurethane-based sealants will result in one that will bond efficiently and seal for years.
While façade design has become increasingly sophisticated and complex, the performance, durability, and appearance remains dependent on the appropriate weather sealing. Without proper joint sealing, it would be impossible to insulate a building sufficiently or protect it from the forces of nature such as wind, rain, or snow. PU-based sealants provide a weathertight seal while minimizing air intrusion and allowing for expansion and contraction. |
