Technical overview
UMaleic SS 35 and SS 210 are rosin ester resins for printing inks, overprint varnishes and selected water-based systems. Their softening point, acid value and viscosity profiles suit different formulation routes; UMaleic SS 210 is the higher-acid-value grade in the range. Compatibility with the main binder, pigment and vehicle must be established, while water-based use requires an appropriate neutralisation or solubilisation process.
Selection considerations
- Formulation roleUMaleic SS grades serve as rosin-derived modifying resins for compatible inks and varnishes.
- Grade characteristicsUMaleic SS 35 and UMaleic SS 210 have different softening-point, acid-value and viscosity ranges.
- ApplicationsApplications include overprint varnishes, printing inks, selected water-based systems and specialty products.
Rosin ester resins technical information
What is a rosin ester resin?
A rosin ester is a modified rosin resin evaluated in inks, coatings, adhesives and related formulations. Its role depends on softening point, acid value, viscosity and compatibility with the complete binder and vehicle system. UMaleic SS grades on this page are intended principally for printing inks and overprint varnishes.
How is UMaleic rosin ester used in water-based inks?
Water-based ink use requires a suitable neutralisation or solubilisation route; the rosin ester does not independently create a finished water-based ink system. Compatibility, solution stability, pigment wetting, print behaviour and finished-film performance must be established before use.
How do UMaleic SS 35 and SS 210 differ?
Softening point, acid value and viscosity distinguish UMaleic SS 35 and SS 210. SS 210 is the higher-acid-value grade in the current range. The shortlisted resin must then be tested with the intended binder, pigment and solvent or water-based vehicle.
Is rosin ester the same as rosin-modified maleic resin?
No. The current catalogue treats UMaleic SS rosin ester grades and UMaleic MR or Unisol M rosin-modified maleic grades as separate product groups. Their technical values, supplied forms and formulation routes differ, so the dedicated page and current grade data should guide selection.
Does Uniform Synthetics supply rosin ester resin from India?
Uniform Synthetics manufactures and supplies UMaleic SS rosin ester resin from India. Provide the ink or varnish type, binder, pigment, vehicle, processing route and destination so the team can confirm the relevant grade, current documents and sample options.
