Boron Nitride

Processing harmony, balancing lubrication, substrate adhesion and release performance
Boron Nitride Coatings

Boron nitride (BN) coatings are excellent candidates for use as release agents or protective coatings for various applications. Momentive Technologies BN coatings are formulated with our high-performance boron nitride powders and carefully selected binder packages to balance release performance, lubrication and adhesion across a wide range of substrate materials.


Momentive Technologies coatings are widely used in metal processing applications, especially for non-ferrous metals such as aluminum, magnesium and other high-temperature alloys. Our portfolio of BN coatings consists of primarily water-based dispersions, but we also offer a quick-drying boron nitride spray and a dry formulation that can be reconstituted at the point of use.

Key Features

Excellent lubrication enables high-performance metal forming applications like forging and superplastic forming

Resistance to chemical attack by non-ferrous metals and high temperature stability minimize concerns of degradation, deterioration or reaction with other components during processing

Excellent release characteristics enable easy separation after forging/forming to improve yield and avoid damage to the final product (work piece) or mold

Excellent adhesion to substrates protects refractory surfaces and underlying materials from molten metals to extend tooling and component life

Potential Applications

Protective coatings for metal processing

Release agents for plastic or rubber molding

Release agents for metal processing

Lubricating coatings for metal processing and metal forming
