Powder coatings suitable for automotive brake pads should possess the following characteristics:
Good Heat Dissipation
The coatings need to effectively dissipate heat generated during friction, preventing overheating that could degrade the coating or reduce braking performance.
High Thermal Resistance
The coatings must withstand the high temperatures generated under normal operating conditions, ensuring stability and functionality at elevated temperatures.
Humidity and Heat Resistance
Stability is crucial under wet conditions, ensuring performance is not compromised by moisture.
Salt Spray Resistance
Good corrosion resistance, particularly against neutral salt spray, is necessary to withstand various climates and road conditions, extending the brake pad's service life.
Environmental Friendliness
The coatings should be solvent-free or low-VOC, minimizing environmental impact and risks to operator health.
Mechanical Properties
Sufficient hardness, toughness, and adhesion are required to withstand mechanical stresses during braking, along with good impact resistance.
Special Additives
Additives such as high-temperature stabilizers and texturizers may be included to enhance specific properties and optimize the coating's micro and macro performance.
