Methyl Methacrylate (MMA)

This paint, which is an epoxy that uses methyl methacrylate as the epoxy resin, is specified by P-620 as “a two-component, minimum 99 percent solids type system”. Polymerized MMA (a different product but close relative) is often sold under the brand name of “Plexiglas”.

Advantages of MMA paint:

• More durable than waterbourne or solvent-based paint. Paint can be expected to last 5 years or more.

Issues with MMA paint:

• Lowest coverage rate (45 ft²/gallon) requires more time and paint.
• Durability means that subsequent removal will require more time and could cause more damage to the underlying HMA.
