Polyurethane Dispersions – A feasible substitute for solvent-based analogs

Over the past few years, there has been tremendous growth in the use of polyurethane dispersions as they are found to be the best and safest replacement for solvent-based coatings along with their environment friendliness.
Also known as PUDs, waterborne polyurethane dispersions are an important ingredient of the polyurethane coating industry which has become popular due to ongoing environment legislations such as the Clean Air Act. There are several advantages associated with their usage.

They are flexible and comfortably comply with the related environment regulations. Moreover, they come in a great variety of hardness and solid content. Their zero to low volatile organic content facilitates their formulation into a compliant coating for many different substrates. Their versatility and wide range of superior properties, such as abrasion resistance, impact strength and low temperature flexibility are the driving forces to their continuously expanding usage in many applications.

Polyurethane dispersion are generally completely reacted polyureas of small and discrete polymer particles ranging from 0.01 – 5.0 microns in a regular water phase. They do not contain isocyanate residues and have a zero or a very low volatile organic content (VOC). Nevertheless, they are safe to handle and are a good choice for compliant coatings.

The importance of waterborne epoxy curing agents

The primary purpose of using waterborne epoxy curing agents is to emulsify, and harden both liquid and solid epoxy resins, yielding tough, durable polymers. A large number of garage coating system comprise of an epoxy or urethane coating product which is bonded to a concrete or a cement floor and it gives a ceramic-type finish upon drying. Most of waterborne epoxy agents consist of a solitary or two-component liquid emulsion which, when mixed, can be used as a primer, sealant and a protective finish. This makes it perfect for a garage floor coating.

With the passage of time, the demand for waterborne epoxy agents has increased a lot. In order to meet this increased demand, more and more companies are now vying to go for their network expansions. This also helps these companies to optimize their market reach and earn huge profits. Moreover, these companies offer customized solutions to their customers, with a constant focus on the improvement in the materials.

The demand for waterborne polyurethane is very high because of its outstanding performance properties in the areas of adhesion, abrasion, chemical resistance, flexibility, and toughness. Moreover, it is the low VOC content associated with these waterborne epoxy coatings that go for waterborne polyurethane dispersions. One important thing to note here is that the waterborne polyurethane coatings are generally characterized by the amazing resistance to abrasion and also high mechanical resistance. This further increases the demand for these materials.
