What is Hydrogenated Rosin Glyceride CAS 65997-13-9?

Hydrogenated Rosin Glyceride is a glycerol ester of hydrogenated rosin, identified by CAS 65997-13-9 and EC number 266-042-9. It is a rosin-derived resin, usually supplied as a pale yellow to amber glassy solid, pellets, flakes, or pastilles depending on the grade.

How does hydrogenation improve this rosin ester?

Hydrogenation reduces unsaturation in the rosin backbone, which improves color stability, oxidation resistance, and resistance to darkening. That makes it useful where a pale, nonoxidizing, color-stable tackifier or resin component is required.

What are the main industrial uses of Hydrogenated Rosin Glyceride?

It is mainly used as a tackifier or resin component in hot-melt adhesives, pressure-sensitive adhesives, coatings, inks, and related sealant or bonding systems. Some grades may also be considered for specialty or food-contact uses where the offered grade and regulatory scope allow.

Which specifications should be checked for adhesive or coating use?

Confirm the supplied form, softening point, acid number, color on the relevant scale, melt or solution viscosity, and compatibility with the target polymer, wax, or solvent system. The optimum values vary by grade and application, so they should be matched to the formulation.

How should Hydrogenated Rosin Glyceride be stored and handled?

Store it in tightly closed containers in a cool, dry, well-ventilated area away from heat, ignition sources, and strong oxidizing agents. Protect pastille, flake, and solid forms from excessive heat and prolonged storage to reduce blocking, lumping, and oxidative color change.

Hydrogenated Rosin Glyceride CAS 65997-13-9

Hydrogenated Rosin Glyceride is a rosin-derived ester material generally used as a specialty resin and tackifier in formulation systems that require adhesion, compatibility, or film-related performance. We supply this product for industrial applications where rosin ester materials are selected according to softening point, acid value, color, compatibility, and end-use processing requirements.

Reference Information

Item	Reference Information
Substance Type	Hydrogenated rosin ester / glycerol ester of hydrogenated rosin
Chemical Nature	Rosin-derived ester resin
Molecular Formula	Not available / not fixed as a single defined formula
Appearance Category	Solid resin / pellets / glassy resin form depending on grade
General Physical Description	Typically pale yellow to amber resinous solid, depending on grade
Structural Note	Esterification product of hydrogenated resin acids / rosin acids with glycerol

The material is treated in regulatory and commercial references as a resin-type substance rather than as one discrete low-molecular-weight compound.

Applications

Typical industrial application directions may include:

tackifier resin for adhesive formulations, depending on compatibility and performance targets
resin component in coating and ink systems, subject to formulation validation
use in pressure-sensitive, hot-melt, or related bonding systems depending on grade and processing route
specialty resin use where color stability, oxidation resistance, or formulation behavior is relevant, depending on application requirements
selected food-contact or specialty uses may exist for some commercial grades, but this must be confirmed against the offered grade and regulatory scope

Any specific end-use suitability should be confirmed according to formulation design, regulatory expectations, and application validation.

For water-based adhesive and coating systems that require a polymer binder rather than a tackifier resin, Styrene Butadiene Latex (SBR Emulsion) is a separate formulation material.

Packaging and Storage

Standard packaging is available. The product may be packed in bags, drums, cartons, or other suitable containers as applicable to the offered grade and supply format. Customized packaging may be discussed upon request.

Store in a cool, dry place in tightly closed packaging. Protection from heat, moisture, and contamination is recommended during storage and handling. Final storage conditions should be aligned with the offered grade and application requirements.
