Technical overview
UMaleic MR and Unisol M are rosin-modified maleic resins for selected paints, lacquers and coating systems. Maleic resin uses in the current range include hammertone finishes, nitrocellulose lacquers, sanding sealers, printing inks, primers and enamels. Softening point, acid value, viscosity, supplied form and solvent compatibility guide selection, followed by testing in the complete binder package.
Selection considerations
- Formulation roleThe grades serve as modifying resins for compatible paint, lacquer and coating binders.
- ApplicationsApplications include hammertone finishes, NC lacquers, sanding sealers, stoving systems, primers and enamels.
- Grade characteristicsSoftening point, acid value, viscosity, supplied form and solvent distinguish the grades.
UMaleic MR or Unisol M grade technical information
What is rosin-modified maleic resin?
Rosin-modified maleic resin is a rosin-derived modifying resin used in compatible paint, lacquer, ink and coating formulations. The current UMaleic MR and Unisol M grades differ in softening point, acid value, viscosity, supplied form and solvent route. They should be evaluated with the principal binder, pigment and solvent package rather than treated as interchangeable products.
What are the main uses of maleic resin in the current range?
Maleic resin uses include hammertone finishes, nitrocellulose lacquers, sanding sealers, printing inks, stoving varnishes, primers and enamels. UMaleic MR 20 serves NC lacquers and sanding sealers, while MR 25 also serves hammertone paints and printing inks. Unisol M 70 is supplied in solution for lacquer and paint applications.
Is rosin-modified maleic resin the same as rosin ester resin?
No. The UMaleic MR and Unisol M maleic products and the UMaleic SS rosin ester products are separate ranges with different specifications and formulation roles. The selected chemistry, acid value, softening point, viscosity, supplied form and compatibility with the main binder must be reviewed before either range is evaluated.
How are UMaleic MR and Unisol M grades selected?
Begin with the main binder, solvent blend, pigment, application method and required drying or bake conditions. Softening point, acid value, viscosity and supplied form narrow the options. The shortlisted grade should then be tested for solution stability, compatibility, application behaviour and finished-film properties in the complete formulation.
What is the difference between solid UMaleic MR and Unisol M 70?
UMaleic MR 20 and MR 25 are supplied as solid beads or flakes, while Unisol M 70 is a 70% solution in mineral turpentine. The supplied form changes handling and solvent contribution, but it does not make the grades interchangeable. Review the individual technical values and intended formulation route before selection.
Can Uniform Synthetics supply rosin-modified maleic resin outside India?
Uniform Synthetics supplies UMaleic and Unisol grades from India to domestic and established international markets. As the rosin-maleic resin supplier for the listed grades, the company can confirm current availability, packaging, sample quantities and product documents for the selected grade and destination.
What information helps with a maleic resin sample request?
Provide the application, principal binder, solvent blend, pigment, processing conditions, drying or bake schedule and target technical values. A current benchmark and required film tests are also useful. This information helps the technical team identify a suitable UMaleic or Unisol starting grade and provide the appropriate current document or sample for evaluation.
