Coatings

UEM now offers piston coatings to help reduce problem areas associated with combustion and wear.

---

Line2Line Adaptive Skirt Technology

• Abradable skirt coating.
• Applied at the total skirt clearance for an initial ZERO fit.
• Hones in to maintain proper oil wedge for a perfect fit to cylinder greatly reducing piston rock.
• Improved ring seal.
• Shock loads and degradation in piston/rod/bearing assembly reduced.

UltraTherm CM

• Heat reflective coating applied to piston crown.
• Lowers piston crown operating temperature.
• Reduces oil temperature.
• Applied at .0015” thick.
• Aids in increasing piston service life by reducing heat transfer to piston.

UltraWear M42

• Standard skirt dry film lubricant.
• Decrease engine noise and helps protect against dry start ups.
• Applied to .0005” per side.

Anodizing

• Limits micro welding of ring to groove in severe conditions.
• Produces a very hard surface for ring to rotate on.
• Piston Crown
• Creates barrier from corrosive fuels.
