The product is Photoinitiator EMK, chemically identified as 4,4'-Dimethylbenzophenone with CAS No. 90‑93‑7. It is supplied by Guangzhou Chengshuai New Material Co., Ltd in Guangzhou, China. The material is presented as an industrial‑grade free‑radical photoinitiator for UV curing formulations. The supplier states the compound is packaged in standard industrial containers and meets ISO and SGS quality checks.
EMK belongs to the class of aromatic ketone photoinitiators that absorb strongly at 365 nm, a wavelength common to most UV curing lamps. In the fine‑chemical market the typical purity for this grade exceeds 99 % and the compound shows good solubility in acetone, ethanol and toluene. Such characteristics make it a reliable choice for resin systems where rapid polymerisation and low volatility are required. The product is listed without a fixed minimum order, allowing buyers to adjust volume to their production schedule.
Major users include manufacturers of coatings, printing inks and adhesive binders that demand fast cure cycles. Trade terms can be arranged on FOB or CIF basis, and the supplier mentions flexible packaging options. Prospective importers should confirm the exact MOQ, lead time and payment method directly with the supplier before placing an order.

Before placing an order, verify that the CAS number, purity and any certificates of analysis match your regulatory requirements. Request the latest ISO and SGS audit reports and compare them with the supplier’s stated compliance. Confirm that the supplier’s harbor trust tier aligns with your risk assessment criteria.
Logistics should be clarified early: ask the supplier to confirm whether the shipment will be under FOB or CIF terms, the expected lead time for production and dispatch, and the preferred payment method such as L/C or T/T. Understanding these details helps avoid unexpected delays and currency exposure. Align the incoterm choice with your own freight forwarder capabilities to streamline customs clearance.
Arrange a pre‑shipment inspection or third‑party quality audit to validate purity, moisture content and packaging integrity. Request a full material safety data sheet, certificate of analysis and any test reports relevant to UV curing performance. Maintaining this documentation supports smooth customs clearance and downstream quality control.
