Superior Polishing and Surface Finishing

Formulated with high-purity Aluminum Oxide (Al2O3), our paste is engineered for outstanding polishing and lapping, delivering a flawless, mirror-like finish on a variety of substrates. Suitable for use in semiconductor, optics, and ceramic industries, it ensures reliable performance and exceptional durability.

Thermal Management and Stability

With thermal conductivity reaching up to 30 W/mK, this paste acts as an effective thermal interface material while maintaining stability across temperatures from -20C to 150C. Its non-conductive nature makes it perfect for electronic and semiconductor applications where both heat dissipation and insulation are critical.

Flexible Packaging and Customization

Available in syringes, jars, or tubes, and customizable to your desired particle size, Aluminum Oxide Paste adapts to your specific requirements. It features a long shelf life of up to 24 months and easy storage, making it a versatile choice for industrial use.

FAQs of Aluminum Oxide Paste:

Q: How should Aluminum Oxide Paste be applied for optimal results?

A: For best results, apply a thin, even layer of the paste to the target surface using a suitable applicator (syringe, spatula, or soft cloth), then polish or lap as required. Its high viscosity ensures good adhesion, and you will achieve a mirror-like finish upon proper usage.

Q: What surfaces are compatible with Aluminum Oxide Paste?

A: This paste is compatible with metals, ceramics, and semiconductor surfaces, making it suitable for a broad range of industrial and technological applications, including electronics, optics, and precision engineering.

Q: When should I consider customizing particle size or packaging?

A: Customization is recommended when your application requires specific abrasiveness, surface finish, or packaging convenience. We offer both sub-micron and micron particle sizes and various packing options to meet distinct requirements in process control and material handling.

Q: Where should Aluminum Oxide Paste be stored to maintain its quality?

A: Store the paste in a tightly closed container, protected from moisture and contamination, in a cool, dry environment. This ensures the products shelf life of up to 24 months is maintained.

Q: What are the main benefits of using Aluminum Oxide Paste in thermal interface and polishing applications?

A: Aluminum Oxide Paste combines efficient heat transfer, electrical insulation, and superior polishing to produce optimal performance. Its non-flammable, non-poisonous, and delivers a high-gloss finish, making it ideal for use in sensitive and high-demand environments.

Q: Is Aluminum Oxide Paste safe and environmentally friendly?

A: Yes, the paste is non-poisonous, odorless, and non-flammable, and meets industrial safety standards. It is safe for handling and use in manufacturing, research, and technical settings.
