Use epoxy curing agent for tough and durable polymers

Why epoxy curing agents are used worldwide? The reason because they are found to emulsify and harden both liquid and solid epoxy resins which eventually delivers tough and durable polymers. You can see numerous applications where these agents bring immense change including concrete polymers/sealers, industrial & decorative concrete floor coatings, wall coatings, high build self-leveling floor coatings, epoxy modified cements, and anti-corrosive primers.

Now you can easily search for the manufactures as a large number of companies are involved into manufacturing these epoxy curing agents and waterborne polyurethane dispersions. The demand for epoxy curing agent arises from businesses involved in coatings, sealants, elastomers, and adhesives. However, it is extremely important to conduct a detailed research before giving purchase order to a particular company. You can refer to internet for your research as this medium is not only cheap but effective as well.

This agent is high in demand due to its outstanding qualities in the fields of adhesion, abrasion, chemical resistance, flexibility, and toughness. An important thing to remember is that poxy curing agents are generally classified by the excellent resistance to abrasion and also high mechanical resistance. This is another reason why the demand for these materials is so high.

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.
