Moisture Scavengers – For an effective protection again moisture

Moisture is known to be the biggest threat for the failure or loss of performance in coatings and sealants. It has an inherent property to react with isocyanate for the production of gaseous carbon dioxide this in turn exhibits bubbling, pinholing and other issues. There are basically two reasons for the onset of moisture. This moisture contamination can induce either from within the formulation or as result of increased atmospheric humidity. It is globally known that solvents may contain some traces of water which can sometimes lead to the dispersion of urea crystals.

However, the introduction of moisture scavengers has made things easy it is meant to bring down the moisture contamination considerably. They are fast reacting and hydrolyze on exposure to moisture. It also eliminates Co2 bubbles and pinholes in two-component systems and minimizes down glossing and hazing under high humidity application conditions.

Moisture scavengers are heavily used for the removal of water from polyols in two component polyurethanes as well as 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.

Polyurethane Prepolymers – Meant for excellent solvents resistance

A large number of industries make the use of polyurethane prepolymers because of their amazing chemical resistance along with solvents and graffiti. The only issue with these prepolymers is their high cost. It restricts their usage and used only in certain applications. They are used in the production of sealants, expansion joints, and adhesives. For more diverse use, they are used on the interior walls of hospitals, schools, and other public buildings.

In short, polyurethane prepolymers are used in those applications that require a great resistance against chemicals and solvents. There are certain advantages of using these agents such as they show amazing weather stability and colorfastness. The advent of these prepolymers has brought great advantage to adhesive and sealant formulators. The formulators can now expect optimum efficiency and enhanced performance benefits, and this is the major reason why these products are high in demand all over the world. Nowadays, there are large numbers of companies involved into the manufacturing of these polyurethane prepolymers and waterborne epoxy agents.

Don’t forget to do a detailed research on polyurethane prepolymers that will help you locating the most perfect manufacturer/supplier for your application. The more dedication you will show in your research, the better results you will get in terms of great chemical resistance and long lasting
