Oxazolidines: An Effective Latent Curing Agent

The latent curing agent is meant for use in a huge range of coatings, adhesives, and sealant applications. They are found to be extremely beneficial in situations that require high build properties. For example, waterproof coatings and construction sealants. Oxazolidines are primarily used as latent curing agents and can be used in both one and two component PU systems.

If there is one component PU system, these latent curing agents are normally used with aliphatic prepolymers. They improve fast through-cure with making no space carbon dioxide gas evolution. On being exposed to moisture, these agents get hydrolysed, resulting into reactive amine and hydroxyl functional groups.

The unmatched properties of this latent curing agent is primarily determined by the curing mechanism, which is completely different from the traditional “moisture cure” reaction. During this process, moisture reacts directly with the terminal isocyanate of the prepolymer producing gaseous carbon dioxide. It results in blisters and bubbles in the coating film.

Moisture majorly reacts with the oxazolidine rather than with the prepolymer’s terminal isocyanate groups. The basic 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.

Why you should go for Waterborne Epoxy Curing Agents

The waterborne epoxy curing agents are widely employed in order to soften and harden both liquid and solid epoxy resins, featuring tough, durable polymers. These agents work as an adhesive to damp concrete. They contain water vapor permeability.

Polyurethane Prepolymers are highly used in the production of coatings, sealants and adhesives. In such cases, curing takes place by making direct contact with atmospheric moisture to deliver rigid, resilient polymers with extraordinary durability. There are various applications of these waterborne Epoxy curing agents including sports & playground surfacing, rubber crumb binder, dust sealer for concrete, polyurethane sealants and polyurethane adhesives.

Some waterborne epoxy curing agents processes in a chemical reaction with the epoxy resign to yield a tough, durable coating. It leads to good stability and epoxy compatibility. It provides total compatibility with cement and calcium salts. Their typical applications include floor and wall coatings, anti-corrosive primers, self-leveling systems, high gloss coatings, clear lacquers, and epoxy floor screeds.

Epoxy Repair Mortars are waterborne reactive polyamine adducts with longer pot life and lower viscosity. It has full compatibility with cement and calcium salts. It is an ideal product for high temperature climates. The applications include floor and wall paints, hygiene coatings, epoxy cement mortars, concrete primers, gloss paints and green concrete coatings.

Waterborne Epoxy Curing Agents and Polyurethane Dispersions

Waterborne epoxy curing agents are in huge demand and are extensively used to emulsify and harden both liquid and solid epoxy resins. And this further yields tough, durable polymers. The high-performance materials (epoxy curing agents and polyurethane dispersions) are used globally by producers of coatings, adhesives, sealants and elastomers. And the demand for the product is increasing with each passing day.

One very well-known producer of oxazolidines, waterborne epoxy curing agents and waterborne polyurethane dispersions is Incorez.

Various Advantages of Waterborne Polyurethane

Although there are numerous products in the market that are being used for a wide range of commercial and personal projects but waterborne Polyurethane Prepolymers have their distinct value and importance. The recent series consist of aromatic waterborne polyurethane prepolymers normally used in the production of coatings, sealants, and adhesives.
During the process, curing takes place by direct contact with atmospheric moisture to deliver tough, resilient polymers with unmatched durability.
The different applications include:
• Sports and Playground Surfacing
• Rubber Crumb Binder
• Dust sealer for Concrete
• Hard, Tough Floor Coatings
• Polyurethane Sealants
• Polyurethane Adhesives
Another kind of prepolymer consists of alipathic waterborne polyurethane prepolymers generally used in the production of sealants, expansion joints, coatings and adhesives.
In this case, curing takes place by direct contact with atmospheric moisture by use of an oxazolidine latent hardener.
The usual applications of this polymer include:
• Adhesives
• Sealants
• High Performance Coatings
• Block Paving Seal
• Concrete Sealer
• Wood Lacquers

Waterborne Polyurethane Prepolymers

The demand for waterborne polyurethane coatings is surging day by day with large number of users using it for the trade coating of wood and parquet floors. Their quality of producing very small amount of volatile organic compounds (VOC) makes them every useful. They are almost odorless and are almost nil polyurethane dispersion available that do not contain N-methyl pyrrolidione (NMP).

It is obvious that new waterborne polyurethane prepolymers require less co-solvent to produce good coatings than the products containing NMP. The waterborne polyurethane coatings are in huge demand due to their unmatched resistance to abrasion and high mechanical resistance properties.

Nowadays, the manufacturers have developed the new polyurethane dispersions by replacing the old polymer mixing process which includes NMP as a solvent with the acetone process. The acetone process requires adjusting the recipes for the dispersions to be responsible for the lower solvent power of the acetone, which is distilled off following the creation of the prepolymer to get a solvent-free product.

Waterborne polyurethane prepolymers offer excellent chemical resistance and high finish. The final product can be used separately or in association with NMP-free polyurethane dispersions as the A component in two-component systems.
