Hikorez Alternative: A-1100 and A-1115 Grade Guide

The closest Milorez screening option for Hikorez A-1100 is MR-C5100, while MR-C5110 is the first grade to evaluate against A-1115. Both pairings are based on resin family, nominal softening point, color, and application window—not guaranteed drop-in equivalence. Kolon’s current public catalog identifies R-1100S as a maleic-acid-modified road-marking resin; Milorez does not claim a direct named equivalent for that chemistry.

What is the Kolon Hikorez series?

Kolon presents Hikorez as a family of hydrocarbon resins covering standard C5, light-color C5, acid-modified C5, and C5/C9 copolymer grades.¹ The standard C5 products are pale-yellow thermoplastic resins made by polymerizing aliphatic olefins and diolefins from the C5 stream generated during naphtha cracking. They are used principally as tackifiers in pressure-sensitive and hot-melt adhesives and as binders in thermoplastic road marking.

Hikorez A-1100 is the best-known 100°C-class grade. Kolon publishes typical values of 100°C Ring-and-Ball softening point, Gardner color 4.5, and thermal stability color 5.5. Its stated uses include pressure-sensitive adhesives, hot-melt adhesives, and hot-melt road marking.²

Hikorez A-1115 is the higher-softening standard C5 option. Its published typical softening point is 112°C, with Gardner color 5. Kolon positions it for solvent-based PSA, hot-melt PSA, and hot-melt adhesive applications.³

For “R-1100” searches, note that Kolon’s current public page lists Hikorez R-1100S. It is a 100°C, Gardner 5 C5 resin modified with maleic acid and intended for hot-melt road marking, where Kolon highlights pigment and filler dispersion, flow, and reduced end-product viscosity.⁴ That modification makes it a different substitution problem from standard A-series C5 resin.

Hikorez-to-Milorez grade mapping

Typical values — screening comparison only; not a cross-approval specification

Hikorez benchmark	Published typical values and use	Closest Milorez screening option	Milorez typical values and use	Qualification note
A-1100	100°C; Gardner 4.5; PSA, HMA, road marking	MR-C5100	Nominal 100°C; Gardner ≤5; PSA, HMA, rubber and road marking	Closest equivalent candidate in the standard C5 window; verify color method, viscosity, compatibility, tack, peel and shear
A-1115	112°C; Gardner 5; SBPSA, HMPSA and HMA	MR-C5110	Nominal 110°C; Gardner ≤5; higher-softening adhesive, rubber and road-marking formulations	Comparable alternative starting point; the 2°C nominal difference does not predict finished-adhesive performance
R-1100S	100°C; Gardner 5; maleic-acid-modified road-marking resin	No direct named equivalent; MR-C5100 may serve only as a non-modified control	Nominal 100°C; Gardner ≤5; general C5 road-marking binder	Do not treat as chemically equivalent; test pigment dispersion, filler wetting, flow, melt viscosity, storage stability and field performance

All values in this table are typical values, not release specifications. Gardner results can differ with molten-resin versus solution methods, solvent, concentration, and conditioning. Request current technical data and compare like-for-like test methods before approving a supplier change.

MR-5910 and MR-5920 are Milorez C5/C9 copolymer grades. They may be relevant when aromatic modification or broader EVA/SBS compatibility is required, but they are not presented as direct alternatives to the standard aliphatic Hikorez A-1100 or A-1115 grades.

When an Asian buyer needs a second source

A pre-qualified China-sourced option can support continuity when Korean-origin resin pricing rises, allocation tightens, vessel schedules change, or lead times become less predictable. This is a contingency scenario, not a claim that a specific disruption is occurring now.

Milorez is a transparent export trading supplier based in Fujian, China. A practical dual-source program keeps the incumbent formulation as the control, qualifies one closest equivalent in the laboratory, and records the acceptable operating window before commercial pressure appears. Price per tonne should be reviewed together with resin loading, coating temperature, line speed, rejects, and freight; a cheaper resin is not a true saving if reformulation reduces output or bond performance.

Five-step sample qualification process

1. Define the benchmark. Send the incumbent grade, current TDS or COA, base polymer, resin loading, application temperature, and pass/fail targets.
2. Select the first screen. Start with MR-C5100 for Hikorez A-1100-type requirements or MR-C5110 for the higher-softening A-1115 window. Flag acid-modified R-1100S requirements explicitly.
3. Request a free sample. Use the sample request form and include the destination country, annual demand, and trial timing.
4. Run side-by-side tests. Compare resin appearance, softening point, color, melt viscosity, and compatibility, then test the complete product for tack, peel, shear, open time, set speed, heat aging, or road-marking flow and dispersion as applicable.
5. Confirm production and supply terms. Complete a controlled line trial, agree the purchase specification and lot acceptance data, then plan against Milorez’s commercial MOQ of 1×20’FCL.

Frequently asked questions

What is the closest Milorez alternative to Hikorez A-1100?

MR-C5100 is the closest screening candidate because it is a light-color C5 aliphatic resin with a nominal 100°C softening point. Final approval still requires formulation testing.

Which grade should be tested against Hikorez A-1115?

Begin with MR-C5110. Its nominal 110°C softening point is close to A-1115’s published 112°C typical value, but compatibility and adhesive performance matter more than a small temperature difference.

Can MR-C5100 directly replace Hikorez R-1100S?

No direct replacement is claimed. R-1100S is maleic-acid modified; MR-C5100 can only act as a general 100°C C5 comparison unless testing proves that the modified functionality is unnecessary.

What should a Kolon Hikorez alternative trial measure?

Measure softening point and color using aligned methods, then compare blend viscosity, compatibility, tack, peel, shear, aging, and any application-specific requirement such as pigment dispersion or road-marking flow.

Are samples free, and what is the commercial MOQ?

Milorez provides a free sample for evaluation. The commercial MOQ is one 20-foot full-container load.

Request a formulation-matched alternative

Review the MR-C5100 grade profile, then request a free sample. Include “Hikorez A-1100,” “A-1115,” or “R-1100S” as the benchmark and send your formulation family, target tests, annual demand, and destination so Milorez can propose the closest comparable alternative without overstating equivalence.
