Technical overview
Unigum E-90, E-95 and E-105 are glycerol esters of rosin used as tackifying or modifying resins in adhesives, inks, paints and related products. Softening point, colour and acid value distinguish the grades, while final selection depends on compatibility with the polymer, binder, oil, wax or solvent package.
Selection considerations
- Three Unigum gradesE-90, E-95 and E-105 have distinct softening-point, colour and acid-value ranges.
- Adhesive trialsThe range serves pressure-sensitive and hot-melt adhesive formulations.
- Other applicationsThe resins are also used in ink, paint, road-marking and sealant formulations.
Ester gum technical information
What is ester gum?
Ester gum is an esterified rosin resin, commonly described as a glycerol ester of rosin. It is evaluated as a tackifying or modifying resin in adhesives, inks, paints and related formulations. Compatibility with the base polymer, binder, wax, oil or solvent package should be confirmed in the complete product.
How do Unigum E-90, E-95 and E-105 differ?
Softening point, colour and acid value distinguish Unigum E-90, E-95 and E-105. The required balance depends on the formulation and processing route. The final choice requires a compatibility trial with the base polymer, wax, oil, solvent and other resins.
Where are Unigum ester gum resins evaluated?
The range is evaluated in pressure-sensitive and hot-melt adhesives, printing inks, paints, road-marking materials, sealants and related products. Each use requires compatibility testing with the specific polymer or binder and the intended production conditions.
Does Uniform Synthetics supply ester gum from India?
Uniform Synthetics manufactures and supplies Unigum ester gum grades from India. Grade availability, packaging, sample options and current product documents can be confirmed for the intended application and destination before a commercial order is placed.
What information helps with an ester gum enquiry?
Provide the application, base polymer or binder, oil and wax package, processing temperature, colour limit and target softening point. A current benchmark is also useful. These details help the technical team identify a suitable Unigum starting grade for compatibility and performance trials.
