Epoxy Vs Polyurethane: Which Coating Is Better?

Epoxy and Polyurethane coatings typify higher indelible qualities like aesthetic appeal, ease of maintenance, and chemical and acid resistance. In this blog, we will discuss some of the differentiating factors between epoxy and polyurethane coating so you can easily decide what product is best for your floor.

Benefits Of Epoxy

Epoxies come in different forms including solvent based, water based, and pure solids. The various types of products will give you varying benefits. At its core, epoxy is a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted either with themselves by catalytic homopolymerisation, or with a variety of co-reactants such as polyfunctional amines, acids, phenols, alcohols and thiols. Reaction of polyepoxides with polyfunctional or with themselves hardeners make a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance.

Epoxies are easy to apply, allow for varying degrees of thickness and provide you a very durable floor that can resist the abuse it receives. The main benefits to epoxies are that they are made with different amounts of VOC levels, this is infact smelly odor that the paint gives off. In most epoxies you can request the low VOC formulations. When applying you will typically mix one part A and one part B to tart the hardening process. After mixing, you can apply this epoxy to your floor and wait to bond to the concrete and cure. Epoxies don’t have a long working time because when mixed the epoxy reacts with the hardener so it is necessary to keep in mind that the time is of the essence.

100% solid epoxies are the strongest and least odor producing epoxies. This means there little to no VOCs in the epoxy as when applied this will give you the strongest coating. It will give an abrasion resistant surface when dry. Epoxy in Pakistan will not only fill in cracks and dings in the floor but thickness will be level when rolled out because of its self-leveling properties.

Benefits Of Polyurethane

Epoxy Vs Polyurethane

Polyurethanes are thermosetting polymers that are used as top coating products on floors.

Aliphatic polyurethane is the most common type as they are anywhere from 55-75% solids and dry 1-4 mils thick depending on application process. They are flexible and allow for good impact resistant. They also have UV stable meaning when sunlight is exposed on it they will not yellow after some time like some epoxies.

Epoxies are much stronger are harder however polyurethane are more scratch resistance. Polyurethanes when applied on surfaces do not bond well to concrete and do not typify the self-leveling properties like epoxies do. Most polyurethanes also have high VOC level and will have quite an odor when applied.

So, what should you choose for your floor?

This depends on the floor application and what the desired result. Epoxy flooring Karachi work for both epoxies and polyurethanes. Epoxy should be used as the base coating and the polyurethane can be used as a topcoat.
