Learn how E-Clips precision cleaning solution removes grease, oil, and residues from metal surfaces before coating or painting. Includes application methods, environmental benefits, and comparison with traditional degreasers.
Surface contamination is the #1 cause of coating failure. Even a microscopic layer of oil can prevent paint, powder coating, or plating from adhering properly. E-Clips is a next‑generation precision cleaning solution designed specifically for metal pretreatment lines.
What Makes E-Clips Different?
Traditional degreasers often rely on harsh solvents, high temperatures, or lengthy dwell times. E-Clips uses a synergistic blend of:
Non-ionic surfactants – For rapid oil emulsification
Corrosion inhibitors – To protect reactive metals like aluminum and zinc
Low-foaming agents – Ideal for spray applications
Chrome‑free & low VOC chemistry – Compliant with global environmental norms
Key Applications
| Industry | Typical Parts | Why E-Clips? |
|---|---|---|
| Automotive | Chassis, brake components, engine parts | Removes stamping oils and coolants; compatible with mixed metals |
| General Engineering | Fabricated sheets, fasteners, springs | Fast cleaning; no residue; ready for phosphating or powder coating |
| Appliances | Steel panels, aluminum trim | Leaves a water‑break‑free surface; improves paint adhesion |
| Aerospace (non-critical) | Brackets, housings | Low foaming; safe for automated spray lines |
Step‑by‑Step Application Guide
Spray Application (Most Common)
Pre‑rinse parts to remove loose dirt.
Apply E-Clips at 2–5% concentration (50–70°C).
Spray for 60–120 seconds.
Rinse thoroughly with demineralized water.
Proceed to conversion coating or painting.
Immersion (Dip) Application
Fill tank with E-Clips solution (3–6% concentration, 60–80°C).
Immerse parts for 3–8 minutes with mild agitation.
Rinse and dry.
Performance Data (Original Lab Results)
*Test method: ASTM F22 (water break test) on cold‑rolled steel contaminated with 2 g/m² of drawing oil.*
| Parameter | E-Clips | Conventional alkaline cleaner |
|---|---|---|
| Cleaning time (spray) | 90 seconds | 180 seconds |
| Water break free surface | Yes, 100% | Partial (approx. 80%) |
| Corrosion on aluminum (24 hrs) | None | Slight etching |
| Operating cost (₹/L of bath) | Low (biodegradable, longer bath life) | Higher (frequent dumping) |
Environmental & Safety Benefits
No heavy metals (chrome, lead, cadmium)
Low VOCs (<5%)
Biodegradable surfactants (OECD 301B)
Non‑flammable & non‑corrosive to equipment
Common Mistakes to Avoid
Using too high concentration – Increases cost and may leave residues. Follow recommended 2–5%.
Insufficient rinsing – Residual cleaner can react with subsequent coatings. Always rinse with clean water.
Cold bath temperature – E-Clips works best at 50–80°C. Lower temperatures reduce cleaning speed.
Conclusion
E-Clips is a reliable, eco‑friendly, and cost‑effective precision cleaner for metal surfaces. Whether you run a spray washer or a dip line, E-Clips delivers consistent, residue‑free surfaces for better coating adhesion and longer product life.
FAQ Section
Q1: What is E-Clips used for?
A1: E-Clips is used for removing grease, oil, machining coolants, and particulate residues from metal surfaces before painting, powder coating, plating, or conversion coating.
Q2: Is E-Clips safe for aluminum and other sensitive metals?
A2: Yes. E-Clips contains corrosion inhibitors that prevent etching or darkening on aluminum, zinc, and galvanized steel, unlike many traditional alkaline cleaners.
Q3: What concentration should I use for spray application?
A3: For spray washers, use a 2–5% concentration of E-Clips in water (typically 3% for medium soiling). Adjust based on oil load and line speed.
Q4: Does E-Clips contain chrome or phosphates?
A4: No. E-Clips is completely chrome‑free and phosphate‑free. It meets RoHS, REACH, and ISO 14001 environmental standards.
Q5: Can E-Clips be used in ultrasonic cleaners?
A5: Yes. E-Clips is compatible with ultrasonic cleaning systems. Use 2–4% concentration at 50–60°C for 3–5 minutes.
Q6: How do I know if E-Clips has cleaned the surface properly?
A6: Perform a water break test. A clean, uncontaminated surface will hold a continuous water film for at least 30 seconds. Beading or breakage indicates residual oil.
Q7: What is the typical bath life of E-Clips?
A7: With proper filtration and oil skimming, an E-Clips bath can last 4–8 weeks in continuous operation. Replace when cleaning efficiency drops or oil content exceeds 5%.
Q8: Is E-Clips compatible with automated dosing systems?
A8: Yes. E-Clips is a liquid product that works with any standard metering pump or conductivity‑based dosing controller.
Q9: What temperature range is recommended?
A9: For best results, maintain 50–80°C. Lower temperatures (30–50°C) are acceptable but require longer cleaning times (up to 50% more).
Q10: Where can I buy E-Clips in India?
