BONDERITE L-FG F 31 – High-Performance Die Lubricant
The world's most widely used die lubricant.
BONDERITE L-FG F 31 ACHESON is, according to the manufacturer, the world's most widely used die lubricant, a water-based graphite lubricant for forging. The concentrate is very stable without separation and delivers consistent quality. To dilute it, water is added to the concentrate while stirring; for initial trials, a ratio of 1:10 is used, but depending on the application, ratios of 1:20 and higher are common.

Bonderite L-FG F 31 – High-performance die lubricant is the world's most widely used die lubricant — a water-based graphite lubricant that is essentially odorless and fumeless, with a unique graphite particle size for higher dilution and longer die gluing life.
Bonderite L-FG lubricants from Henkel/Acheson are specially formulated for forging and extrusion applications — water- or oil-based graphite and MoS₂ dispersions with excellent lubrication and release properties at high tool temperatures. L-FG F 31 is tailored to specific industrial applications — the most important properties and areas of application are listed below.
Bonderite L-FG F 31 (formerly Deltaforge F-31) is the world's most widely used die lubricant — essentially an odorless and fumeless, water-based graphite lubricant. Its unique graphite particle size and special stabilizer/binder provide excellent lubricity, faster wetting, higher dilution ratios, and longer die holding time.

Frequently asked questions about L-FG F 31
Practical application and design questions — answered by SILITECH.
Bonderite L-FG F 31 – High-performance die lubricant: The world's most widely used die lubricant — a water-based graphite lubricant that is essentially odorless and fumeless, with a unique graphite particle size for higher dilution and longer die sticking time. Main applications: Hot forging of steel, precision forging, and hot forging of steel.
Forging release agents are applied to the hot forging tool — at tool temperature, they form a lubricating film of micro-fine graphite (or synthetic lubricants in graphite-free variants such as F 605). They reduce friction between the workpiece and the die, extend tool service life, and enable higher dilution ratios. Bonderite L-FG 31 + F 31 (Deltaforge) are the most widely used standards worldwide.
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).
