Our Rosin Modified Maleic Resins are high-melting thermoplastic resins engineered through the precise esterification of gum rosin with maleic anhydride and polyhydric alcohols. These resins serve as high-performance binders and film-formers across a variety of solvent-based ink and coating systems. Dromal Rosin Modified Maleic Resins series is meticulously developed to meet the technical benchmarks of the ink and coating industry, characterised by superior solubility profiles right from total solubility in alcohols (IMS) to high compatibility with hydrocarbon solvents (MTO/Toluene). Chemical structure of Rosin Modified Maleic Resin, formed by the Diels-Alder reaction of maleic anhydride with rosin acids, provides a significantly higher melting point and harder film compared to natural rosins. This technical modification facilitates rapid solvent evaporation and fast tack-free times, critical for high-throughput manufacturing environments. The low acid-value grades are specifically designed for use in moisture-sensitive systems, while high acid-value variants offer the necessary functionality for water-reducible and high-polar solvent formulations, ensuring Total Cost of Quality is minimised through optimised pigment loading, reduced solvent consumption, and consistent film performance. We are the leading Rosin Modified Maleic Resins series suppliers, ensuring consistent melting points and viscosity profiles across the Dromal series. We provide a comprehensive range of synthetic resins with full technical (Acid Value/Melting Point/Solubility) and supporting quality assurance documentation (COA/TDS/SDS). Our products are optimised for high-performance printing inks and industrial lacquers, offering superior gloss and adhesion. We ensure reliable lead times upto 10MT+ commercial supply, enabling partners to lead the market in high-efficiency coating manufacturing.

Chemical Properties & Specifications
High-speed printing on paper, corrugated board, and plastic films. Providing high gloss, rapid solvent release, and excellent rub resistance required for modern packaging
Nitrocellulose (NC) lacquers and wood finishes to increase solids content, enhance film hardness, and improve the drying speed of the final coating
Durable binder in thermoplastic road markings, ensuring high adhesion to mineral substrates and resistance to abrasion
Improves gloss and pigment wetting of air-drying enamels, providing superior colour development and stability in architectural and industrial finishes
Alcohol-soluble grades are primary binders for polishing varnishes and paper coatings, offering high clarity and high-gloss aesthetics
Solvent compatibility is dictated by the resin's chemical modification. Alcohol-soluble grades like Dromal M 2353 are designed for flexographic inks used on food packaging, where low-toxicity solvents are required. Conversely, toluene-soluble grades like Dromal 2351 are used in gravure inks and industrial lacquers where high evaporation rates and strong resin-solubility are the primary technical drivers.
Pure Nitrocellulose (NC) can produce brittle films with low gloss. Incorporating Dromal 2352 increases the solids content of the lacquer without significantly increasing viscosity, leading to a higher-build finish with improved hardness and gloss. This reduces the number of coating layers required, lowering both labor costs and material consumption.
Dromal 2354 provides an exceptionally high acid value (230 Max), making it suitable for systems that require high polarity or subsequent neutralization for water-solubility. Scientists value this grade for its ability to act as a pigment grinding aid in aqueous systems, ensuring stable dispersions and high color yield.
We bridge the gap between technical production and global regulatory safety. Every shipment includes a batch-specific Rosin Modified Maleic Resins COA/TDS and a GHS-compliant SDS. Our rosin-modified resins are REACH registered, ensuring Sourcing Managers have the necessary documentation to clear international technical audits and customs inspections.
We support large-scale ink and coating manufacturers with a standard lead time of 7–8 Weeks for commercial volumes (10MT+). Resins are typically supplied in 25 Kg paper bags or PE-lined woven bags to prevent moisture ingress and block-caking during long-term storage.
