## Frequently Asked Questions

### Technical Questions

Q: Why is low chlorine content critical in epoxy resins for electronics?
A: Chlorine exists in two forms: total chlorine (bound in polymer) and hydrolyzable chlorine (reactive, easily released). Hydrolyzable chlorine forms chloride ions in moisture, causing: (1) Electrochemical migration - chloride ions enable metal ion migration between conductors, creating short-circuit dendrites; (2) Copper corrosion - direct attack on copper traces; (3) Reliability failures months or years after deployment. Industry standards require total chlorine <500 ppm and hydrolyzable chlorine <100 ppm for standard semiconductor packaging. Automotive-grade requires <50 ppm total and <10 ppm hydrolyzable. IndexChem UH grades meet these demanding specifications.

Q: What is the difference between Bisphenol A (BPA) and Bisphenol F (BPF) epoxy resins?
A: Key differences: BPA epoxy (ZLA Series) has viscosity 3,500-14,000 mPa·s, excellent mechanical properties, can crystallize at low temperatures but is remelted easily - best for EMC encapsulants, die attach, electronic adhesives. BPF epoxy (ZLF Series) has viscosity 1,000-3,500 mPa·s (significantly lower), lower crystallization tendency, slightly higher chemical resistance - best for vacuum infusion (wind blades), underfill, applications requiring excellent flow. Choose BPA for general electronics; choose BPF when low viscosity is critical.

Q: What epoxy resin specifications are required for semiconductor packaging?
A: Tiered requirements: Standard applications need total chlorine <500 ppm, hydrolyzable <100 ppm (IndexChem S grades). High-reliability (industrial, medical) needs total <100 ppm, hydrolyzable <50 ppm (IndexChem U grades). Automotive and aerospace (highest reliability) needs total <50 ppm, hydrolyzable <10 ppm, meeting JEDEC and AEC-Q100 standards (IndexChem UH grades).

Q: What epoxy resin is best for wind turbine blade manufacturing?
A: Wind blade infusion requires: low viscosity (1,000-3,000 mPa·s) for complete fiber wet-out over 100+ meter distances; extended pot life for large parts; high fatigue resistance for 20+ year service. IndexChem recommends ZLF-160 Series (1,000-1,400 mPa·s BPF epoxy) for main spar and shell infusion, or ZLV-165/175 (cost-optimized A/F blend) for large-volume production.

Q: How are epoxy resins used in EV battery manufacturing?
A: Key applications: (1) Structural bonding - cells to modules, modules to packs for crash resistance; (2) Thermal management - thermally conductive adhesives transferring heat to cooling plates; (3) BMS potting - protecting electronics from vibration and moisture; (4) Cell-to-pack bonding for higher energy density. Requirements include -40°C to +85°C operating range, flame retardancy, low outgassing. IndexChem supplies European EV gigafactories in Germany, Hungary, Poland, and France.

### Compliance Questions

Q: Are IndexChem epoxy resins REACH compliant for the European market?
A: Yes, fully REACH compliant under EC 1907/2006. Benefits: registered products, seamless import across 27 EU member states, no additional registration required. For UK customers: separate UK REACH compliance maintained for Great Britain; Northern Ireland follows EU REACH under Windsor Framework. Documentation provided: TDS, SDS in required languages, batch-specific CoA, REACH registration confirmation.

### Commercial Questions

Q: What are the delivery times for epoxy resin orders to European countries?
A: IndexChem maintains strategic European inventory. Standard times: Benelux 2-3 days; Germany/Austria/Switzerland/France 3-4 days; UK 3-4 days; Italy/Spain/Poland 4-5 days; Nordics/Portugal/Eastern Europe 5-7 days. Shipping options: DDP (Delivered Duty Paid - we handle customs), DAP (customer handles import), Express available for urgent orders.

Q: How does IndexChem pricing compare to Japanese epoxy suppliers?
A: IndexChem offers equivalent or superior specifications at 20-40% lower total cost of ownership versus established premium suppliers. Achieved through: efficient modern manufacturing, direct manufacturer relationship, lean operations focused on electronic-grade epoxy. Same chlorine specifications (down to <50 ppm total, <10 ppm hydrolyzable), equivalent viscosity ranges, full REACH compliance, local European support. No quality compromise - savings come from supply chain efficiency.

Q: How can I get samples to evaluate IndexChem epoxy resins?
A: Complimentary technical samples for qualified industrial customers. Process: (1) Contact with application requirements; (2) Technical team recommends optimal grade; (3) Ship 500g-1kg samples with TDS, SDS, CoA; (4) Technical support during evaluation. Samples typically ship within 3-5 business days. Contact info@indexchem.eu.

Q: What is the minimum order quantity (MOQ)?
A: Evaluation samples: no MOQ, complimentary 500g-1kg. Commercial orders: standard products minimum 25 kg per grade, specialty grades minimum 50 kg, volume pricing for orders exceeding 500 kg. Packaging: 25 kg drums (standard), 200 kg drums or IBC for high-volume.
