Photoresist Stripper (NMP-BASED)

Description

1. Product Overview

This high-purity Cleaning Solvent (FLUX REMOVER) is an engineered formulation specifically designed for the rapid, residue-free elimination of rosin-based, no-clean, and water-soluble flux residues from printed circuit boards (PCBs) and electronic assemblies. Its primary industrial use lies in post-soldering cleaning processes within electronics manufacturing, where ionic contamination directly impacts product reliability. The key value proposition is a non-flammable, low-global-warming-potential (GWP) solvent that delivers consistent surface insulation resistance (SIR) values above regulatory thresholds while reducing cleaning cycle times by up to 40%. Strategically, this product is critical as miniaturized electronics and high-density interconnects demand defect-free surfaces to prevent leakage currents, electrochemical migration, and field failures.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Proprietary azeotropic blend of hydrofluoroether (HFE) and trans-dichloroethylene (t-DCE); zero ozone-depleting substances (ODP=0)

• Purity Level: ≥99.8% active solvent content; ionic impurity level <10 ppm total (chlorides, sulfates, sodium)

• Physical Characteristics: Transparent, colorless liquid; mild ethereal odor; boiling point 45–48°C; density 1.32 g/cm³ @ 20°C; non-flammable (no flash point per ASTM D3278)

• Packaging Options: 1L aerosol (with dip tube), 5L steel canister, 20L UN-approved safety drum, 200L closed-head steel barrel

• Shelf Life: 24 months from date of manufacture when stored in original sealed container between 5–35°C

3. Core Industrial Applications

• Primary Industries: Aerospace & defense electronics, automotive powertrain modules, medical device manufacturing, telecommunications infrastructure, and contract electronics manufacturing (CEMs)

• Specific Use Cases: In-line spray cleaning after wave soldering; manual stencil wipe between print cycles; ultrasonic immersion for hybrid microcircuits; selective cleaning of fine-pitch QFN and BGA components

• Performance Advantage: Unlike IPA or hydrocarbon-based removers, this solvent penetrates under low-standoff components (<0.1 mm) via capillary action, then evaporates completely without white residue or substrate hazing. It removes both activated and unactivated flux without attacking polycarbonate displays, polyester labels, or acrylic conformal coatings—eliminating secondary masking steps.

• Cost Advantage: 30% lower consumption per unit PCB compared to aerosol-only alternatives due to near-100% evaporative efficiency and no post-rinse requirement; reduces rework rates by an average of 18% in controlled trials.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 certified production with batch-specific Certificate of Analysis (CoA) including FTIR spectra and ionic contamination per IPC-9202; lot-to-lot variation <0.5%.

• Supply Reliability: Dual-continent manufacturing (Americas & EMEA) with safety stock buffer of 60 days; average on-time delivery rate 99.3% over 24 months.

• Logistics Capability: Pre-qualified with DGM and FedEx for airfreight; UN-classified as non-hazardous for transport under DOT 49 CFR §173.132 (Limited Quantity exemption).

• Price Competitiveness: Tiered volume pricing at 15–22% below C8 fluorosolvent market average while exceeding J-STD-001 cleanliness standards (ionograph reading <1.5 µg/in² NaCl equivalent).

• Sustainability: Zero HAPs (hazardous air pollutants); fully recyclable via closed-loop distillation service; <100 GWP (vs. 1,430 for HFC-based removers).

• Technical Support: 24/5 application engineering access; free contamination audit kit with validated cleaning process protocol per your SMT line configuration.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 200 liters (net) – equivalent to 10 x 20L drums or 1 x 200L barrel

• Bulk 20MT Order Quantity: 20 metric tons net (approx. 18,180 liters at density 1.10 g/cm³ for bulk calculation; actual density 1.32 g/cm³ yields ~15,150 liters per 20MT – buyer must confirm density-adjusted tonnage)

• Loading Capacity per Standard 20FT Container: 72 x 200L drums = 14,400 liters net (19.0 metric tons gross), or 5,760 aerosols (12 pallets of 480 units)
