What is Polyaspartic?
To better understand Polyaspartic, let’s first look at Polyurea, from which it is derived.
Polyurea is an elastomer that is formed by mixing an isocyanate with a synthetic resin. Typically, the 2 components require specialised spray equipment that applies high pressure (2500psi) and warm temperature which allows the ISO and Resin to mix and sets off a chemical reaction which forms the finished Polyurea material. The reaction is very aggressive and from the time the 2 components react in the tip of the spray gun it can take as little as 3-5 seconds for the product to tack off, and 10 seconds to be touch dry. Whilst there are many benefits to such a rapid reaction, it does limit certain applications due to requiring large, expensive spray equipment, and the need for a spray enclosure/extraction.
Polyaspartic, like polyurea, is formed by mixing together an ISO and Resin, albeit a modified formula that has a less aggressive reaction. The result is a durable waterproof coating resistant to harsh chemicals impact and abrasion with the benefit of longer pot life and the ability to mix with simple hand tools and apply either by roller or low-pressure spray equipment. These qualities make Polyaspartic perfect for flooring applications where mobilisation of complex spray equipment is not available/cost effective and is suited to a large range of residential flooring and commercial flooring applications where strength, performace and quality is paramount.

So How is Polyaspartic different to Epoxy Floor Coatings
Like Epoxy flake flooring, Polyaspartic is a seamless flooring system that can have decorative flakes or granules added for visual effect, perfect for residential and commercial applications. Whilst the finished products can have a similar appearance initially when completed, there are significant differences in the chemistry which makes ASPART-X superior across a number of key features.
The major difference between the Polyaspartic and epoxy floor coatings is how they react with the substrate. Epoxy is a topical coating meaning it sits on top of the substrate and is relying on griping to the surface such as a concrete surface and in most cases requires to be used in conjunction with a primer. ASPART-X however, penetrates deep within the concrete substrate and is the only coating of its type that improves the strength and integrity of the substrate. This gives ASPART-X superior adhesion as well as resistance to abrasion, impact, chemicals and hot tyre pick up.
Another benefit is that unlike Epoxy floor coatings, ASPART-X is 100% solids, meaning no VOC's (Volitile Organic Compound, otherwise known as solvents), which offer greater flexibility when it comes to application. With increased resistance to harsh chemicals, faster application times, faster return to service and UV stability, ASPART-X is the #1 choice for a wide variety of concrete flooring applications.
