Brake Fluid Can

Q: Why is tinplate the best material for brake fluid packaging?
A: Tinplate (tin-coated steel) offers:

• Extreme Corrosion Resistance: Withstands highly corrosive glycol-based (DOT 3, 4, 5.1) and silicone-based (DOT 5) fluids.

• Zero Permeability: Blocks moisture, oxygen, and UV light to maintain fluid dryness (<0.5% water content) and prevent vapor transmission.

• Rigidity: Protects against denting/rupture during transport, ensuring seal integrity.

Q: How do you prevent moisture absorption and leakage?
A: Our cans feature:

• Epoxy-Phenolic Interior Lacquer: Food-grade barrier coating to isolate fluid from metal.

• Hermetic Sealing: Double-seamed base + nitrogen-flushed crimping under inert gas.

• Triple-Seal Caps: Threaded closures with EPDM/FKM gaskets + foil induction liner for 100% moisture/leak proofing.

Q: Are your cans compliant with automotive safety standards?
A: Absolutely. We meet:

• FMVSS 116 (DOT 3/4/5.1/5): Material compatibility validated via SAE J1703/J1704 testing.

• ISO 4925: Packaging requirements for non-petroleum brake fluids.

• UN 1A2 Certification: Passed drop, stack, and pressure tests for hazardous liquid transport.

Q: How do you prevent metal ion contamination in silicone-based (DOT 5) fluids?
A: Critical for performance! We use:

• Passivated tinplate with chromium oxide layer

• Fluoropolymer interior coating (e.g., PTFE-modified epoxy)

• Rinse testing per ASTM D1118 (copper strip corrosion ≤1b)

Q: Are cans compatible with low-viscosity EV brake fluids (e.g., DOT 5.1 ESP)?
A: Yes. Optimized for high-performance fluids:

• Zero silicone migration from seals (per ISO 4925 Annex E)

• Passes -40°C to 150°C thermal shock cycling

• ≤0.02% evaporation loss (SAE J1703)
