Buying it right
Phthalo green, often typed as phalo green, is the strong, clean green of the ink and paint trade. The grade decides how far it goes: some stop at paint, others survive the extruder.
Green 7 HD-G covers inks, paints and general use, and HD-8730K takes plastics at 280°C. Green 36 goes to 350°C and covers powder coating.
Each grade comes with the Choksi data and the standard it replaces. Ask the pigment team for samples of the two greens side by side.
The partnership
Support
Samples, datasheets and technical answers come straight from the team that makes the product. Formulation advice, matching against your current reference and follow-up after delivery are part of the partnership, included from the first order.
Product
Seven registered brands, from Dragon Dyes to Chemtech, all backed by Hongda's in-house R&D teams. Dyes, pigments, additives and functional chemicals come from the same group, so you can widen your catalogue while keeping a single supplier.
Experience
Documentation, logistics and compliance are routine here after three decades of cross-border trade. Hongda exports to more than 30 countries and works with over 500 distributors worldwide, so the paperwork your market requires has most likely been solved here before.
Supply
You buy at origin, in the quantities a distributor needs to stay competitive in its market. Volume pricing, consolidated shipments and production planned around your forecast give you the economics to defend margin against any local reseller.
