Formulating High Weatherability Sealants: Possibilities and Challenges


Customers challenge sealant formulators to develop high weatherability construction sealants with ever-higher performance. This paper will discuss some of the factors that influence weatherability and durability of sealants, such as binder, pigments, stabilizers, and catalysts. One-component polyurethane and modified silicone sealants will be evaluated. Raw material influences need to be carefully tested and optimized in order to develop high weatherability sealants. Taking these factors into consideration, it is possible to formulate high weatherability sealants that meet customers' demands. These demands are expected to increase in the future.
