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.

Stick and stay stuck : Optimizing performance for pressure-sensitive adhesives / Scott Krusinski in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 26, N° 7 (07/2019)

Consider this: A new type of plastic was selected for an automotive headlamp component. Nothing else has changed in the manufacturing process—but it should have been. Now the water seal, an ethylene propylene diene terpolymer (EPDM) foam die cut laminated with pressure-sensitive adhesive, is not bonding to the new plastic and is simply falling off. In another scenario, the materials for a new building insulation bonded perfectly for the first six months of use, and the new product was a hit. Then summer came along, temperatures began to rise, and the insulation materials started to delaminate and fall apart. In every situation, two main considerations—the materials being bonded and the environment of the application—can make all the difference in pressure-sensitive adhesive success or failure. When selecting adhesives for certain materials, you must consider the surface energy and texture of those materials. You must also consider the environmental conditions (e.g., temperature and humidity) that these materials will be subjected to. Specifying the proper adhesives and working with converters and adhesive manufacturers is a key element in designing any new product or revising an existing one. Knowing the basic properties of an adhesive is a start. Factors beyond that must be also considered, and the best time to do that is early in the design stage.
