 Applications 

1. Unsaturated Polyester, Alkyd & Gel Coat Resins — UPR, gel coats, marine and construction resins, alkyd binders: An acid building block for the polyester backbone, providing the unsaturation that later crosslinks with styrene. Water-soluble and easy to charge, it lets the reactor run at lower temperature than the anhydride route and gives better control over the exotherm during esterification.

2. Water Treatment & Scale Inhibition Polymers — polymaleic acid, maleic-acrylic copolymers, dispersants and antiscalants: The monomer behind a whole class of low molecular weight polymers used to inhibit carbonate and sulphate scale and to disperse iron oxide and suspended solids. The polymer backbone is highly resistant to hydrolysis and to chlorine attack, which is why it holds up in cooling towers and reverse osmosis systems.

3. Printing Inks & Coating Resins — rosin-maleic adducts, ink varnishes, paper and board coatings: Reacts with rosin to form maleated rosin resins that give gloss, pigment wetting and quick solvent release in publication and packaging inks. Also used to build water-based and high-solids coating resins.

4. Lubricant, Fuel & Oilfield Additives — dispersants, pour-point depressants, corrosion inhibitors, drilling fluid additives: The maleic backbone is the anchor for grafted and copolymer additives that keep soot and sludge dispersed in lubricants and fuels, and for filming amines and scale-control chemistry used in oilfield water systems.

5. Paper, Textile & Leather Processing — surface sizing, dyeing auxiliaries, leather treatment: Used to build the polymeric sizes and finishing agents that improve paper strength and printability, and as an acid component in textile and leather auxiliaries.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
