Q1: What is Saracure 379 and what class of photoinitiator is it?
A1: Saracure 379 (CAS 119344-86-4, mol. wt. 380.53) is a Free Radical Type I photoinitiator — also known commercially as Omnirad 379 — that is highly efficient for initiating photopolymerization of unsaturated prepolymers in combination with mono- or multifunctional monomers. It appears as a white to light yellow powder with purity NLT 98%.
Q2: What makes Saracure 379 especially well-suited for pigmented UV-curable systems?
A2: Its molecular design enables strong absorption and efficient radical generation even in the presence of pigments that scatter or absorb UV light, making it especially suitable for pigmented UV-curable coatings, photoresists, and printing plates — applications where many photoinitiators fail due to light attenuation by pigment particles.
Q3: In which specific industries is Saracure 379 (Omnirad 379) widely deployed?
A3: It is widely used in the UV curing field across Graphic Arts (printing inks), Electronics (photoresists, solder masks, PCB imaging layers), and UV-curable coatings — markets where fast, reliable photopolymerization under challenging conditions is critical.
Q4: What hazard classification and transport requirements apply to Saracure 379?
A4: Unlike several other photoinitiators in the Saracure range, Saracure 379 is classified as a hazardous material (UN No. 3077) — meaning it requires UN-approved packaging and appropriate hazmat documentation for transport, which buyers must factor into their logistics planning.
Q5: Is Sarex the manufacturer and exporter of Saracure 379 (Omnirad 379) from India?
A5: Yes, Sarex is a leading fine chemical manufacturer and exporter in India, producing Saracure 379 at 50 MT annual capacity and supplying it in 25 kg corrugated box pallets to UV-curing, graphic arts, and electronics chemical producers in more than 40 countries.
