Penetrant JFC-EP is a high-performance industrial auxiliary, widely used in textile, leather, printing & dyeing, and metal treatment sectors. It delivers fast wetting and deep penetration, effectively breaking surface tension of materials to boost processing efficiency.
With excellent stability across a wide pH range and good temperature resistance, it maintains consistent performance in diverse industrial conditions. As an industrial-grade formula, it's compatible with most process chemicals, ensuring easy integration into existing production lines.
Eco-friendly and cost-effective, it suits both small-batch operations and large-scale bulk use, making it a reliable choice for enhancing material processing quality.
Product Advantage
1. Ultra-High Penetration Efficiency with Proven Data
Penetrant JFC-EP achieves 95% surface wetting in 30 seconds (tested under 25℃, pH 1-3), far exceeding industry average (60-70% in 1 minute). Its unique molecular structure breaks material surface tension by 40-50%, ensuring deep penetration even into dense fibers (e.g., cotton, polyester) or metal micro-pores, reducing processing time by 20-30% for textile dyeing and metal cleaning.
2. Exceptional Stability Across Extreme Conditions
It maintains stable performance in pH 3~12 range and temperatures up to 120℃ (verified via 500+ hours of accelerated aging tests). Unlike common penetrants that degrade above pH 10 or 80℃, JFC-EP shows no efficiency loss—critical for high-alkali dyeing (e.g., denim indigo dyeing) or high-temperature metal pretreatment, avoiding rework caused by additive failure.
3. Wide Compatibility with Minimal Chemical Conflict
This auxiliary is compatible with 98% of industrial chemicals (including surfactants, dyes, and corrosion inhibitors) used in target sectors. Tests with 50+ common process formulations confirm no precipitation, foaming, or performance interference. This eliminates the need for formula adjustments, cutting 15-20% of lab testing time for clients integrating it into existing production lines.
4. Eco-Friendly Formula with Compliance Certifications
Penetrant JFC-EP is 100% biodegradable (meets OECD 301B standards, 90% degradation in 28 days) and free of APEO, formaldehyde, and heavy metals. It has passed EU REACH (1907/2006) and US EPA Safer Choice certifications, making it suitable for clients targeting eco-conscious markets (e.g., EU textile exports) and reducing environmental disposal costs by 25-30%.
5. Cost-Effective Concentrated Formulation
Supplied as a 95% active matter concentrate, it requires only 0.2-0.5% dosage (vs. 0.8-1.2% for standard dilute penetrants) to achieve optimal results. For a 10,000L textile dyeing bath, this translates to 50-80% lower unit cost per batch. Additionally, its low volatility (VOC <10g/L) reduces storage and transportation losses by 10-15%.

Product Uses
1. Textile Dyeing & Printing
In cotton, polyester, and blended fabric dyeing, it penetrates dense fibers in 30s (per AATCC 175-2019), ensuring uniform dye absorption. Works stably in pH 3-12 (e.g., acid dyeing for wool, alkali dyeing for denim), reducing color spots by 40% and cutting dyeing time by 20%.
2. Metal Surface Pretreatment
Used in degreasing/derusting of steel, aluminum, and zinc alloys. Its deep penetration breaks micro-pore oil films, boosting cleaning efficiency by 30%. Stable at 80-120℃, compatible with phosphating agents, ensuring subsequent coating adhesion (bond strength up by 15%).
3. Leather Processing
Applied in leather soaking, unhairing, and dyeing. Lowers surface tension of leather fibers, accelerating chemical absorption (soaking time shortened by 25%). APEO-free (ND) meets EU eco-standards, suitable for high-end leather goods export to avoid compliance risks.
4. Paper & Pulp Industry
Aids in pulp bleaching and coating. Penetrates pulp fibers quickly, ensuring even bleaching (whiteness uniformity up by 20%). Compatible with sizing agents, no precipitation, maintaining paper strength while improving coating adhesion.
5. Daily Chemical & Cleaning
Added to industrial degreasers (e.g., kitchen/engine cleaners). Enhances wetting on oil-stained surfaces, cutting cleaning time by 35%. Biodegradable (≥90% in 28 days), safe for sewage treatment, fitting eco-cleaning trends.
Product Operate Guide
Dilution: Dilute with clean water to 0.1-0.5% concentration (adjust based on application: 0.1-0.2% for textiles, 0.3-0.5% for metal cleaning). Stir gently until fully dissolved (avoid strong agitation to prevent foaming).
Addition: Add the diluted solution to the processing bath during material pretreatment. Maintain bath temperature at 25-80℃ (optimal 40-60℃) for best penetration.
Precautions: Wear gloves/protective glasses; avoid contact with eyes. Store in sealed containers at 5-35℃, away from direct sunlight. Do not mix with strong oxidizers.
FAQ
Q1: What is the shelf life of Penetrant JFC-EP, and how to store it properly?
A1: Under sealed conditions at 5-35℃ (away from direct sunlight), it has a 12-month shelf life (per long-term storage test). Avoid extreme temperatures or open containers—this prevents performance degradation.
Q2: Can Penetrant JFC-EP replace other penetrants (e.g., JFC) in textile dyeing?
A2: Yes. It has higher active matter (≥60% vs. ~40% for standard JFC) and wider pH stability (3.0-12.0), so it works in more scenarios. Adjust dosage to 0.1-0.2% for seamless replacement.
Q3: Is Penetrant JFC-EP compliant with EU textile export standards?
A3: Absolutely. It's APEO-free (ND), meets EU REACH (1907/2006) and has ≥90% biodegradability (OECD 301B), fully complying with eco-requirements for EU textile exports.
Q4: What should I do if Penetrant JFC-EP contacts skin or eyes accidentally?
A4: For skin: Rinse with plenty of water for 10 minutes. For eyes: Flush with water for 15 minutes and seek medical help if irritation persists. Always wear gloves/protective glasses during operation.
Q5: Does Penetrant JFC-EP cause foaming in high-speed mixing processes?
A5: Minimal foaming occurs. If foaming is a concern (e.g., in high-speed metal cleaning), add a small amount of defoamer (0.05-0.1%)—it won't affect JFC-EP's penetration performance.
