Latent Curing Agent – Developed to deliver performance

A latent curing agent is primarily meant for usage in different types of coatings, adhesives, and sealant applications. The reason why they are immensely used is they tend to be very powerful in situations that feature high build properties. For example, waterproof coatings and construction sealants. Oxazolidines is majorly used as a latent curing agent and can be used in both one and two component PU systems.
In case of one component PU system, these latent curing agents are generally used with aliphatic prepolymers. They promote fast through-cure with leaving no space for carbon dioxide gas evolution. On being come into contact with moisture, these agents get hydrolysed, resulting into reactive amine and hydroxyl functional groups.

The unrivaled properties of this latent curing agent is majorly distinguished by the curing mechanism, which is entirely different from the traditional “moisture cure” reaction. During this process, moisture reacts directly with the terminal isocyanate of the prepolymer emissioning gaseous carbon dioxide. It results into blisters and bubbles in the coating film.

Moisture heavily reacts with the oxazolidines rather than with the prepolymer’s terminal isocyanate groups. The fundamental process of hydrolysis and ring opening of the oxazolidine generates amine and hydroxyl groups. These amine and hydroxyl groups then subsequently react with the isocyanate of the prepolymer without the evolution of carbon dioxide gas.

Know more about Epoxy Curing Agents

When it comes to find manufacturers of Oxazolidines, there are large numbers of manufacturers all around the world who are involved into the manufacturing of Oxazolidines, waterborne polyurethane dispersions. Thus it is obvious that placing an order is no longer a mind-boggling task with the presence of so many manufacturers. These materials are heavily demanded by various industries and businesses dealing into coatings, sealants, elastomers, and adhesives with the help of internet, one can easily browse through the complete range of manufacturing companies involved into the manufacturing of these products.

The main purpose of epoxy curing agents is to emulsify and harden both liquid and solid epoxy resins, delivering tough and durable polymers. Their uses include concrete primers, industrial & decorative concrete floor coatings, anti-corrosive primers, and epoxy modified cements. In today’s competitive business environment, these agents play an important role among different industries and huge in demand all across the world.
