BN-T40 Boron Nitride Coating For Aluminum Release
Sep 28, 2026
Key Features of BN-T40
(1)High-Temperature Anti-Stick Performance
The h-BN-based formulation provides strong non-stick properties under high-temperature operating conditions, helping reduce molten-metal adhesion to properly prepared surfaces.
(2)Lubricating Effect
The layered structure of hexagonal boron nitride provides solid lubricating characteristics, making BN-T40 suitable for high-temperature applications where conventional lubricants may not be appropriate.
(3)Protective Interface
The coating forms a protective interface between molten metal and the substrate, helping reduce direct contact and metal buildup on casting equipment.
(4)Water-Based Formulation
BN-T40 uses a water-based system and can be applied by brush or other suitable methods according to the application requirements.
(5)Strong Adhesion
BN-T40 is designed to provide good adhesion to suitable metal and ceramic substrates. A relatively thin coating can provide the intended release effect; excessive coating thickness should be avoided.
Typical Applications
BN-T40 can be used on suitable surfaces in:
· Molten Metal Runners
· Molten Metal Containers
· Degassing Equipment
· Ingot Dividing Molds
· Stirring Rods
· Crucibles
· High-Temperature Casting Tools
· Aluminum Processing Equipment
The actual suitability depends on the substrate, working temperature, coating method, and operating conditions.
How to Apply BN-T40
Proper surface preparation and coating thickness are important for achieving consistent performance.
1. Stir Before Use
Thoroughly stir BN-T40 before application to ensure a uniform coating.
2. Clean the Surface
Remove oil, dust and other contaminants from the mold or equipment surface before coating. A clean substrate helps improve coating adhesion.
3. Apply the Coating
BN-T40 can be applied directly by brush or suitable manual coating methods.
4. Avoid Excessive Thickness
BN-T40 has good adhesion and does not need to be applied excessively thick. An overly thick coating may be more likely to flake during use.
5. Heat Before Operation
After application, gradually heat the coated component to the required working temperature before normal operation.
6. Dilution
BN-T40 can be diluted with water according to the customer's application requirements and operating habits.
Technical Support and After-Sales Service
The performance of a boron nitride coating depends not only on the coating itself, but also on the substrate, surface preparation, coating thickness, drying/heating conditions and working environment.
Zibo Shengyang New Material Co., Ltd. provides application-oriented technical support, including:
· BN-T40 product selection
· Application method guidance
· Substrate compatibility consultation
· Coating thickness recommendations
· Dilution guidance
· Sample testing support
· Troubleshooting assistance
· Batch supply and long-term cooperation
If you experience problems such as metal sticking, coating flaking, uneven coating or insufficient service life, please provide the substrate material, working temperature, application method and operating conditions. Our technical team can help analyze the possible causes.
Why Choose BN-T40?
For metal casting operations, unwanted molten-metal adhesion can increase cleaning requirements and affect the condition of molds and tools.
BN-T40 is designed to provide a practical anti-stick, release and protective interface for high-temperature casting applications.
Its h-BN-based formulation combines:
Anti-Stick + Lubrication + High-Temperature Stability + Surface Protection
The actual performance depends on the specific application conditions, which is why product selection and application guidance are important.
