Get superior moisture protection with moisture scavengers

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.

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.

Moisture Scavengers – Benefits Unlimited

Here are the benefits when moisture scavengers are used in a two-component polyurethane system:

o No bubbles and Pinholes

o Improves Adhesion

o Improves Abrasion and Chemical Resistance

o Improves Downglossing and Hazing

o Eliminates Gassing

However, this is not all. There are many more benefits when a company uses these moisture scavengers in a two-component polyurethane system. Moisture scavengers are heavily used in urethane coatings, elastomers, and sealants. And this is why; these scavengers are always in demand in various industries around the world. Moisture scavenger can easily eliminate moisture from the raw materials in a urethane system. It is to be noted that components of urethane systems come with amounts of moisture. At present, there are numerous companies in the market which are manufacturing moisture scavengers. Almost all of them have their online presence where they enlist all their products and services.

No doubt, moisture scavengers provide numerous benefits. However, make sure that you choose a reliable manufacturer/supplier for your business-needs. And now, with online resources, it is easy for you to browse as many suppliers as you want, and then, choose a reliable one. Besides moisture scavengers, you can also place order for oxazolidines, waterborne epoxy curing agents, polyurethane dispersions, polyurethane prepolymers, and co-solvent free polyurethane dispersions.
