For the closest equivalent starting point to SUKOREZ SU-100, screen Milorez MR-H100 first. For a SUKOREZ SU-400 alternative, MR-H100 is also the first water-white 100°C-class candidate, but SU-400’s aromatic-modified hydrogenated route makes polymer compatibility a decisive test. Choose MR-H110 only when a higher softening-point target is useful. MR-D100 is standard DCPD resin, not a water-white hydrogenated replacement.
No Milorez grade should be approved as an automatic equivalent from a trade name or softening point alone. The terms closest equivalent and comparable alternative on this page mean a candidate for side-by-side qualification.

What is the Kolon SUKOREZ series?
Kolon describes SUKOREZ as a family of water-white hydrogenated hydrocarbon resins made by polymerizing and hydrogenating cyclic components. Published benefits include low color and odor, heat stability, solubility and compatibility with polymers such as EVA, SIS, SBS and APAO. Typical uses include hot-melt adhesives, hygiene-product HMPSAs and polypropylene modification.
The chemistry differs across the range. Kolon groups SUKOREZ SU-100 with its hydrogenated DCPD resin family and publishes a typical 105°C ring-and-ball softening point. SUKOREZ SU-400 is grouped with hydrogenated DCPD-C9 copolymer resins; its product page describes a hydrogenated C5 aliphatic/C9 aromatic route and publishes a typical 100°C softening point. That aromatic contribution can alter compatibility even when two resins have similar color and softening point.

Typical values — published Kolon reference data and Milorez grade-selection starting points; not sales specifications or an equivalence guarantee
| Benchmark or route | Chemistry position | Typical softening point / color | Milorez screening choice | Selection meaning |
|---|---|---|---|---|
| SUKOREZ SU-100 class | Hydrogenated DCPD family | 105°C; Hazen 30 | MR-H100 | Closest water-white hydrogenated 100°C-class starting point |
| SUKOREZ SU-400 class | Hydrogenated DCPD-C9 / aromatic-modified route | 100°C; Hazen 30 | MR-H100 first; MR-H110 if a higher softening class is required | Match compatibility and rheology, not only appearance |
| Higher-softening water-white branch | Hydrogenated resin | Nominal 110°C Milorez selection point | MR-H110 | Useful when the trial needs more softening-point margin; not a direct SU-100 or SU-400 match |
| Standard DCPD branch | Unhydrogenated DCPD resin | Nominal 100°C Milorez selection point | MR-D100 | Not equivalent where water-white color, low odor or hydrogenated aging performance is required |
Request the current TDS before setting limits. Compare color using one matched scale, solvent concentration and method; then align softening point, acid value, melt viscosity, molecular-weight distribution and hot-aging behavior. For SU-400 replacement work, add cloud point or compatibility testing in the actual EVA, SIS, SBS, SEBS, APAO or metallocene-polyolefin system.
Hygiene and transparent-product substitution
Hydrogenated tackifiers are relevant to disposable hygiene construction because white nonwovens and films expose color and odor problems quickly. A candidate must also survive heated storage and application while providing wetting, peel, creep resistance and reliable bonds at converting speed. Kolon lists both SU-100 and SU-400 among resins recommended for pressure-sensitive hygiene hot melts.
For clear tape, labels, packaging adhesives and transparent polymer modification, assess haze, initial color, yellowing after heat or UV exposure, compatibility and surface appearance. A resin that looks water-white as pellets can still haze in a finished blend or lose clarity after aging.
These are formulation benefits, not regulatory claims. Low odor, low color or use in a hygiene adhesive does not prove skin-contact, food-contact or medical compliance. Define the finished article’s requirements and review documents for the exact grade and supply source. See the broader hydrogenated hydrocarbon resin guide for application cautions.
Free-sample qualification process
- Define the benchmark. Send the SUKOREZ grade, current TDS, complete polymer system, resin loading, process temperature and pass/fail targets.
- Select the route. Start with MR-H100 for a 100°C-class water-white trial, MR-H110 for a higher-softening branch, or MR-D100 only when an unhydrogenated DCPD resin is technically acceptable.
- Run a controlled comparison. Test incumbent and candidate in one fixed recipe. Record compatibility, cloud point, melt viscosity, tack, peel, shear or creep, haze and initial odor.
- Age the formulation. Compare color and odor after realistic hot-pot exposure, storage and UV or thermal aging. Then confirm spray, coating or extrusion behavior on a pilot line.
- Approve commercially. Agree the purchase specification, methods, packing and COA requirements only after the technical trial passes.

Frequently asked questions
What is the closest Milorez equivalent to SUKOREZ SU-100?
MR-H100 is the closest starting point in the water-white hydrogenated 100°C class. It remains a comparable alternative requiring formulation and line approval.
What should I test as a SUKOREZ SU-400 alternative?
Screen MR-H100 first, but verify aromatic-sensitive compatibility with the actual polymer. Test MR-H110 only when a higher softening-point class is desired.
Is MR-D100 a hydrogenated SUKOREZ equivalent?
No. MR-D100 follows the standard, unhydrogenated DCPD route and should not replace SU-100 or SU-400 when hydrogenated color, odor and aging performance are essential.
Can the alternative be used in hygiene or transparent products?
Potentially, after complete formulation testing and document review. Water-white appearance is not proof of regulatory suitability.
Are samples free, and what is the MOQ?
Samples are free for qualification. The commercial MOQ is one 20-foot full container load.

Frequently asked questions
What is the closest Milorez equivalent to SUKOREZ SU-100?
MR-H100 is the closest Milorez starting point for a water-white hydrogenated resin in the 100°C softening-point class. It is a comparable alternative, not a certified drop-in equivalent; approve it through formulation, aging and line trials.
What should I test as a SUKOREZ SU-400 alternative?
Start with MR-H100 when water-white appearance and an approximately 100°C class lead the requirement. Because SU-400 is an aromatic-modified hydrogenated route, confirm compatibility with EVA, SIS or SBS rather than assuming chemistry equivalence. MR-H110 is the higher-softening alternative branch.
Is MR-D100 a hydrogenated SUKOREZ equivalent?
No. MR-D100 is a standard DCPD resin, whereas SU-100 and SU-400 belong to hydrogenated resin families. Screen MR-D100 only when the formulation can accept the color, odor and aging profile of an unhydrogenated DCPD route.
Can a comparable resin be used in hygiene or transparent products?
Potentially, after application testing and document review. Evaluate odor, aged color, clarity, viscosity, substrate bonding and emissions in the complete formulation. Water-white appearance alone does not establish hygiene, food-contact or medical suitability.
Can I sample a Milorez grade before placing an order?
Yes. Milorez offers free samples for formulation screening. Send the incumbent grade, polymer system, recipe, process conditions and pass/fail criteria. The commercial MOQ is 1 × 20-foot FCL.
