When it comes to determine the biggest threats affecting the performance of coatings and sealants, moisture occurs at top with many issues. This is why moisture has an inherent property to react with isocyanate for the production of gaseous carbon dioxide which in turn results into bubbling, pinholing, and many other issues. This moisture impurity can start either from within the formulation or as result of increased atmospheric humidity. It is universally known fact that solvents may contain some traces of water which can sometimes lead to the dispersion of urea crystals.
The good things is that the evolution of moisture scavengers has made things easy and they play a major role in bringing down the moisture contamination drastically. They are quick reactant and hydrolyze on exposure to moisture. It also eliminates CO2 bubbles and pinholes in two-component systems and reduces glossing an hazing under extreme humidity application conditions.
Moisture scavengers are widely used for the removal of water from polyols in two component polyurethanes along with the removal of water from solvents, plasticisers, and pigment pastes. It prevents gassing and gelling in single component systems. Incorez is a global leader in oxazolidine chemistry, manufacturing a diverse range of products marketed under the Incozol® umbrella.
