Product Description
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 firmly adhering film with low coefficient of friction and release properties. L-GP BN 4479 FA is tailored to specific industrial applications — the key properties and areas of application are listed below.
Bonderite L-GP BN 4479 FA (formerly ENDU BN 4479 FA) is a colloidal dispersion of crystalline boron nitride in a solvent — an anti-adhesion coating serving as an anti-diffusion barrier for titanium alloys. High-temperature resistance up to +1'000 °C in air, +2'000 °C in inert atmospheres. Specifically designed for SPF-DB technology (Superplastic Forming / Diffusion Bonding).

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.
After evaporation of the carrier (water, solvent, or MIBK), dry film lubricants form a firmly adhering lubricating film of solid lubricant (graphite, MoS₂, PTFE, or boron nitride). Advantages over liquid lubricants: no migration, lifelong lubrication in many applications, high-temperature suitability, substrate versatility (wood, metal, plastic, glass), electrically conductive possible (graphite) or highly insulating (boron nitride).
Store in the unopened original container in a dry, cool place — typically between +5 and +40 °C, exact values see TDS. Protect water-based products from frost. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Store aerosol sprays at low temperature and in a well-ventilated area.
In the comparison table above, you will find related Bonderite products with different properties — different carrier, different solid lubricant, different temperature range, or different application specialization. If you are unsure about the optimal choice, we will be happy to advise you — contact SILITECH with your specific application (substrate, temperature, load, processing workflow).
