Single-Component Polyurethane Systems

In moisture curing single-component polyurethane systems, the cross-linking of the isocyanates takes place through a reaction with moisture from the surrounding atmosphere once the polyurethane coating is applied.

The presence of moisture in raw materials can initiate the hardening reaction prematurely in storage, leading to loss of shelf life.

This problem can be avoided by using a SYLOSIV® molecular sieve. It adsorbs the unwanted moisture during storage, so that undesirable reactions cannot take place.
