Bonderite L-GP BN 4479 FA is a colloidal boron nitride dispersion in solvent (ENDU BN 4479 FA) as an anti-diffusion barrier for titanium alloys — high-temperature protective coating up to +1,000 °C in air, +2,000 °C inert.

Bonderite L-GP dry film lubricants from Henkel/Acheson — graphite, PTFE, MoS₂, or boron nitride dispersions that, after drying, form a tightly adhering film with a low coefficient of friction and release properties. L-GP BN 4479 FA is tailored to specific industrial applications — the most important properties and areas of application are listed below.

Boron nitride inert up to +1,000 °C / +2,000 °C

Bonderite L-GP BN 4479 FA (formerly ENDU BN 4479 FA) is a colloidal dispersion of crystalline boron nitride in solvent—an anti-adhesion coating used as an anti-diffusion barrier for titanium alloys. It offers high-temperature resistance up to +1,000 °C in air and +2,000 °C in an inert atmosphere. Specifically designed for SPF-DB technology (Superplastic Forming / Diffusion Bonding).

processing

1
clean substrate
Thoroughly degrease and dust the bonding surfaces — Bonderite L-MR or Permabond Cleaner A.
2
Stir the dispersion
Homogenize thoroughly before use — for concentrates, dilute with the specified solvent if necessary.
3
Apply
Spraying, dipping, brushing or, in the case of aerosols, spraying on — an even, thin layer.
4
Solvents evaporate
The carrier substance evaporates — in the case of water-based products, heat can accelerate drying.
5
Polymerization/Curing
At room temperature, typically 15 minutes (BND60A, D31A) to several hours — some require heat curing (e.g. 150 °C for L-GP 333-1).
6
Mission
Dry film ready for use — in high-temperature applications, the film continues to harden, improving its properties.

Frequently asked questions about L-GP BN 4479 FA

Practical application and design questions — answered by SILITECH.

Bonderite L-GP BN 4479 FA: Colloidal boron nitride dispersion in solvent (ENDU BN 4479 FA) as an anti-diffusion barrier for titanium alloys — high-temperature protective coating up to +1,000 °C in air, +2,000 °C inert. Main applications: Superplastic Forming Titanium (SPF), Diffusion Bonding (SPF-DB), high-temperature metal forming.

Dry film lubricants form a firmly adhering lubricating film of solid lubricant (graphite, MoS₂, PTFE, or boron nitride) after the carrier substance (water, solvent, or MIBK) evaporates. Advantages over liquid lubricants include: no migration, lifetime lubrication in many applications, suitability for high temperatures, substrate versatility (wood, metal, plastic, glass), and the possibility of electrical conductivity (graphite) or high insulation (boron nitride).

Store in the unopened original container in a dry, cool place — typically between +5 and +40 °C, see TDS for exact values. Protect water-based products from freezing. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Store aerosol sprays at a low temperature and in a well-ventilated area.

In the comparison table above, you will find related Bonderite products with different properties—different carrier media, different solid lubricants, different temperature ranges, or different application specializations. If you are unsure about the optimal choice, we would be happy to advise you—contact SILITECH with your specific application (substrate, temperature, load, processing workflow).
