Which coating is most scratch resistant?

Which coating is most scratch resistant?

• A. Polyurethane
• B. Latex
• C. Acrylic
• D. Enamel

Answer: (A)

Scratch resistance depends on how hard and durable the finish film becomes as it cures. Polyurethane forms a hard, dense, crosslinked film that stands up well to abrasion, scuffs, and small scratches, making it less likely to show wear on surfaces that get touched or bumped. Latex paints are softer and more flexible, so they can show marks or wear more easily. Acrylic finishes can be quite durable and hard, but they generally don’t reach the same level of abrasion resistance as polyurethane in typical use. Enamels can be hard, but their durability against scratching isn’t consistently higher than a well-applied polyurethane topcoat, especially on high-traffic surfaces. So, when scratch resistance is the goal, polyurethane is the strongest choice among these options.
