NPI-601 is a general free radical photoinitiator based on phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide. It offers high curing activity, long absorption wavelengths (377 nm and 405 nm), and excellent deep-curing and photo-bleaching performance. It is particularly suitable for LED-curable coatings and inks, and is often used as a more active complement to TPO.

Frequently Asked Questions
What is your minimum order quantity (MOQ)?
MOQ depends on the product and specification. For most chemicals we can supply from 1 kg sample orders up to full container loads (FCL). Contact us with the product name and CAS number for a specific MOQ quotation.
Can you provide samples before I place a bulk order?
Yes. Samples are available for most products — typically 100g to 1kg. Sample fees may apply for expensive products and are usually deducted from your first bulk order. We recommend independent testing of samples before committing to bulk.
What documents do you provide with each shipment?
Every shipment includes a batch-specific Certificate of Analysis (COA), MSDS/SDS, commercial invoice, packing list and bill of lading. Certificates of origin, REACH/SVHC declarations and third-party inspection reports are available on request.
What is your typical lead time?
Production usually takes 10–20 days depending on the product and quantity. Sea freight to most destinations takes 15–30 days; air freight 5–10 days for samples and small orders. Our five warehouses in China allow fast dispatch of stocked items.
What payment terms do you accept?
We commonly accept 30% deposit + 70% against copy of bill of lading, T/T bank transfer, and Letters of Credit (L/C) for larger orders. Payment terms are confirmed in writing before production starts.
Are you a factory or a trading company?
We are an integrated supplier with three in-house manufacturing plants, supported by five warehouses across China. This gives us direct control over production quality while maintaining a broad product range.
