What Is a MMA Surface Coating?

A mma surface coating is an excellent solution for high-traffic areas that require a tough, long-lasting compound. This two-component paint combines pigments and polymer curing agents that are mixed together and applied directly to the concrete. Once the mixture dries, it creates a strong and durable coating that is resistant to impact and chemical exposure.

Methacrylate butadiene styrene (MMA) is a versatile resin that can be used in a variety of applications and industries, including flooring. Its durability, strength, and flexibility make it ideal for commercial and industrial flooring projects. MMA resins also have an incredibly quick cure time, making them a practical option for businesses that need to minimize downtime.

MMA is an aliphatic, non-toxic polymer that’s often blended with vinyl and epoxy to provide superior adhesion. It can also be combined with urethanes, phenolics, and other acrylic monomers to produce an array of coatings. Because of its versatility, MMA is one of the most popular coatings for industrial flooring. It has a number of advantages over other structural adhesives, including a quick cure and good moisture resistance.

In the past, MMA was seen as a less costly alternative to epoxies, but this trend has changed recently. As a result of supply chain disruptions and force majeures, the price of MMA has gone up significantly. This has put pressure on major producers to limit sales, resulting in a reduction in availability for customers.

During the MMA process, methyl methacrylate (MMA) and butyl methacrylate (BMA) are mixed to form polymethyl methacrylate (PMMA). This material is clear, hard, and resistant to UV-radiation, making it ideal for coating applications in a variety of environments.

Due to its aliphatic properties, MMA is resistant to saponification and alkali breakdown. This makes it an excellent choice for coating zinc substrates. In addition, MMA is very easy to use in waterborne systems.

An important attribute of MMA is its ability to bond to itself and existing surfaces, meaning that there’s little need for extensive surface preparation prior to application. This can significantly reduce the amount of downtime required for a flooring project, especially if you’re working in an environment with limited accessibility.

The MMA layer also serves to protect the substrate from corrosion by acting as a barrier that limits ion access. Potentiodynamic and electrochemical impedance spectroscopy (EIS) testing show that coated samples have a lower corrosion current (ic) and lower corrosion potential () than uncoated samples.

The unique properties of MMA also allow it to be used in temperatures as cold as -20°F, which is ideal for construction sites and other unheated buildings where it’s necessary to speed up the flooring project. This feature can also be useful for supermarkets that need to resurface large cold storage facilities but don’t want to waste time heating the area. In addition, MMA is not as sensitive to moisture during the critical curing period as other structural adhesives, so it’s a great choice for resurfacing a cold store.
