Boron Nitride Coatings

Boron nitride coatings are advanced functional materials composed primarily of boron and nitrogen atoms arranged in various crystal structures, including hexagonal and cubic forms. These coatings combine exceptional thermal stability, chemical inertness, and lubricating properties, making them ideal for high-performance industrial applications. Unlike traditional coatings, boron nitride coatings can maintain integrity under extreme temperatures and aggressive chemical environments, providing both protective and functional advantages to substrates. Their versatility has attracted growing attention in fields ranging from electronics and metallurgy to aerospace and chemical processing.

Why Choose Boron Nitride Coatings

Boron nitride coatings provide a clean and efficient alternative to conventional, pollution-heavy coatings. They are highly suitable for challenging manufacturing processes, including mold release in aluminum, titanium, and copper casting, as well as glass shaping and optical lens production. The coatings enhance the precision and surface quality of molded products, reduce the rate of mold deterioration, and prolong mold durability. In addition, they support environmentally responsible manufacturing by meeting strict ecological standards, making them a sustainable choice for high-performance industrial applications.

What We Offer

The boron nitride coating products we can offer are as follows:

Type	Catalog Number	Construction Method	Applications
Water-Based Paste-Acidic	ALCM-BN-06	Roll/brush/spray/dip coating	Tailored for use in the melting and casting of alloys including aluminum, magnesium, and zinc, this coating creates a durable barrier when applied by rolling or brushing, effectively stopping molten metal from seeping into the refractory surface. While its mildly acidic nature helps reduce metal oxidation, it is important to keep it away from iron or steel components to avoid potential corrosion.
Water-Based Cream-Neutral	ALCM-BN-07	Roll/brush/spray/dip coating	A versatile mold release coating compatible with a wide range of metal casting processes, it is especially well-suited for scenarios where molds have no special material limitations. It greatly enhances mold durability, and the surface quality of cast components can improve by over 20% once the parts are released.
Water-Based Paste-Alkaline	ALCM-BN-08	Roll/brush/spray/dip coating	Engineered for use with alkaline melts like copper alloys, this coating provides strong protection against chemical attack from molten slag on the mold surface. It performs exceptionally well in glass hot bending processes, minimizing the bonding between the heated glass and the mold.
Ionic Water-Based Liquid	ALCM-BN-09	Roll/brush/spray/dip coating	With just one spray, it forms an ultra-thin nanoscale protective layer, making it particularly well-suited for high-precision casting and optical glass manufacturing. Thanks to its excellent cleanability, it has become the release agent of choice for die-casting metal housings in 3C product applications.
Ionic Oil-Based Liquid	ALCM-BN-10	Spray can	Featuring an organic solvent carrier, this formulation allows the coating to form quickly and endure temperatures as high as 1200 °C, making it perfectly suited for aerospace forging applications. Its lightweight and mobile design makes it convenient for on-site operations, including the protection of metal pipes during welding and other maintenance tasks.
