What’s the difference between MMA, PU and Epoxy Flooring?

difference between MMA, PU and Epoxy Flooring

Three primary types of resin flooring are available: Methyl Methacrylate (MMA) resin, polyurethane, and epoxy. Each MMA resin variant offers distinct features and benefits, which we'll delve into extensively while comparing them to other resin flooring options. Degafloor exclusively provides fast-curing methyl methacrylate (MMA) resin. Thanks to its exceptional and unique benefits, Degafloor effectively meets the diverse needs of customers across various industries.

MMA resin flooring cures significantly faster than Epoxy and Polyurethane flooring

Cure times affect how quickly an installation can occur and then how quickly the floor can be returned to full use – or other trades come back into the area to work. When a resin floor has reached a physical cure, it is trafficable, however, chemicals are still released into the air until the resin reaches a full chemical cure.

Cure Types Degafloor MMA Flooring Epoxy/Polyurethane Flooring
Time to full physical cure

(I.e. able to fully traffic)
2 hours 12-48 hours
Time to full chemical cure 

(i.e. able to fully use)
2 hours 3-10 days

Nearly all resin systems are installed in multiple layers – primer, main body coat layer and seal coat/s. As Degafloor products cure fully in just 2 hours, there is no real downtime between the application of each layer.

Most epoxies and polyurethanes typically need at least 4 – 8 hours to cure between applications, resulting in significantly longer installation periods.

 MMA resin types are thermoplastics.

MMA resin types are thermoplastics which achieve a chemical bond between each installation layer, resulting in a monolithic finish. In reality, each new layer chemically fuses to the previous layer (or existing subfloor) creating a virtually unbreakable bond.

Epoxy and polyurethane resins are thermosetting and achieve only a mechanical bond between installation layers. In reality, each new layer ‘sticks’ to the previous layer (or existing subfloor).

Degafloor resin flooring systems do not shrink

Degafloor resin flooring systems do not shrink and accordingly, installation is both simple, repeatable and the finished floor reliable.

Polyurethane resin floors often require retention chases to be cut into the floor and at all termination points to try and offset the shrinkage stresses that occur when the floor cures. This complicates the installation and can result in performance problems.

Degafloor MMA resin can be bonded directly to drainage channels and other potential areas of weakness to create reliable and durable installations.

In many cases, polyurethane and epoxy finishes will require an expansion joint to be installed in these areas which may create points of weakness.

 

Degafloor offers a range of MMA flooring solutions to meet varying slip resistance requirements.

This is especially true of industrial environments, where outstanding performance is required.

The Degafloor Full Broadcast and Quartz Trowelled with Aggregate systems utilise quartz aggregate which stays suspended at the top surface of the system, creating a consistent and textured finish that delivers market-leading performance.

Most polyurethane systems are trowel-applied and rely on the installer leaving part of the aggregate within the resin mix ‘exposed’ to create slip resistance. This method often results in an inconsistent surface finish and, together with early wear, can result in unsatisfactory slip resistance.

Degafloor MMA Resin are UV resistant

Degafloor resins are totally UV resistant and do not become brittle with age. Many polyurethane resins are not UV resistant creating long-term performance issues, including discolouration. Additionally, some epoxy formulations have been proven to become brittle over time resulting in poor long-term performance.

Product Temperature Resistance
Epoxy up to 60°C 
Degafloor MMA Resin up to 80°C
Polyurethane up to 120°C
