Bonderite BONDERITE-L-GP-D31A (400-ml-Aero)

BONDERITE® L-GP D31A High Temperature Graphite Lubricant Aerosol

Overview

BONDERITE® L-GP D31A (formerly Pulvegraph D31A) is a high-temperature graphite aerosol lubricant formulated to provide durable dry-film lubrication and heat-resistant protective coatings. Based on pure lamellar graphite, it produces a low-friction coating that polymerises at room temperature and continues to harden when exposed to elevated temperatures. Designed for applications up to and beyond 1,000°C, it is ideal for foundry, forging, glass manufacturing and other industrial processes requiring dry lubrication under extreme heat.

Approvals & Specifications

• Manufactured by Henkel under the BONDERITE® industrial lubricant range
• Designed for high-temperature dry-film lubrication applications
• Suitable for industrial processes operating up to 1,000°C and above

Performance Highlights

• Provides excellent dry-film lubrication at extremely high temperatures
• Polymerises at ambient temperature within approximately 15 minutes
• Film hardness and abrasion resistance increase with operating temperature
• Resistant to heat, wear, washing and abrasion after curing
• Withstands exposure to temperatures exceeding 1,000°C
• After light curing at 100°C, the coating becomes insoluble in common solvents
• Excellent release properties for tooling and mould applications

Typical Applications

• Glass manufacturing moulds and bottle deflectors
• Foundry moulds and pins
• Gravity die casting lubrication
• Pressure die casting plunger treatment
• Forging dies
• Titanium forging operations
• Oven chains and high-temperature moving components
• General high-temperature dry lubrication

Compatibility & Safety Notes

• Apply only to clean, degreased surfaces
• Spray onto surfaces below 55°C
• Use with adequate ventilation
• Contents are flammable
• Avoid contact with skin and eyes
• Refer to the Safety Data Sheet (SDS) before use
• Store between 5°C and 40°C

Application & Curing

• Thoroughly degrease the surface before application
• Shake the aerosol vigorously for at least 30 seconds before use
• Spray from a distance of approximately 15-20 cm
• Apply only to surfaces below 55°C
• Film polymerises in approximately 15 minutes at ambient temperature
• Light curing at 100°C significantly improves solvent and abrasion resistance
• Further hardening occurs naturally during high-temperature service

Packaging & Procurement

• Supplied in convenient aerosol spray cans
• Coverage: Approximately 7 m� per can
• Available through Henkel BONDERITE® distributors worldwide

Why This Product is Chosen for AOG / MRO

• Provides reliable dry lubrication where conventional lubricants fail
• Excellent performance in extreme heat environments
• Clean aerosol application simplifies maintenance work
• Improves release properties on tooling and high-temperature components
