The chemistry behind lasting color.

Yes. The group operates under ISO 9001 quality management and ISO 14001 environmental management. Both certificates can be opened from the seals on this page.

Four product groups: textile chemistry, pigments and colorants, performance additives and functional chemicals, sold under seven registered brands such as Dragon Dyes, XINTI and Transcor.

Seven registered brands: Hongda, Dragon Dyes for dyes, XINTI for titanium dioxide, America Screens for printing screens, Transcor for pigments, Chemtech for additives and Digicolor for instrumentation.

Yes. The catalog covers 24 product lines, each with its own brochure including series, physical data and shade or color index information. Samples and datasheets come directly from the teams that make the product.

Yes. The reactive dyes line is made for cotton and cellulosic fibers, with a shade range for both exhaust dyeing and printing, documented in its own brochure.

Disperse dyes: the Dragonperse range in AC-E, UN-SE and CXF series with a full shade card, plus a newer washable disperse series with improved wash fastness for polyester and its blends.

Disperse dyes are insoluble colorants that penetrate hydrophobic fibers such as polyester under heat; fiber reactive dyes bond chemically with cellulose, so they are the choice for cotton. Hongda supplies both, plus Americascreens nickel rotary screens for textile printing.

Titanium dioxide is the white pigment that gives opacity and brightness to coatings, plastics and inks. Hongda sells it under the XINTI brand, with grades for each application and a technical datasheet per grade.

Organic pigments for inks, paints and plastics with a printed color card by color index number, and inorganic pigment powders: iron oxide in red, yellow, black and brown, ultramarine blue heat stable to 350 °C, and XINTI titanium dioxide.

Phthalo blue and phthalo green are phthalocyanine organic pigments with high tinting strength for inks, coatings and plastics; ultramarine blue is an inorganic pigment with a redder shade, non migrating, FDA and EN71-3 certified. Hongda supplies all three.

Yes. Fluorescent pigments in the HK, HP, HT, HW and HX series for textile, plastic and coating uses, alongside solvent dyes and metal complex dyes for plastics coloration.

Chemtechnox hindered phenol antioxidants for PE, PP, PA, PVC, ABS and polyester processing, plus wax additives for slip, scratch resistance and matting in plastics.

Chemtech coating additives for wetting, dispersing, leveling and defoaming, together with wax additives for slip, scratch resistance and matting effects in inks and coatings.

Hongda's chlorinated rubber is a fast-drying resin documented for anticorrosive, marine and road-marking paints. Suitability for a specific pool paint formulation is confirmed with a sample and the technical datasheet.

Primary, secondary and tertiary amines carry one, two or three carbon groups on the nitrogen, which changes their reactivity. Hongda supplies amines and amine intermediates for coatings, agrochemicals and fine chemical synthesis, with series and physical data in the brochure.

The biocides line covers in-can preservation of water-based formulations, dry-film protection of coatings and industrial water treatment systems.

Yes. Samples and datasheets for biocides and amines come from the teams that make them, and every line has a downloadable brochure.
