MR-C5110 is Milorez’s comparable aliphatic C5 alternative for buyers evaluating the Wingtack 95 application space. It is not a one-for-one softening-point match: public Wingtack 95 data reports about 98°C, while MR-C5110 is a nominal 110°C grade. That difference can be useful when more cohesive or warm-temperature performance is wanted, but it requires a controlled reformulation trial.

What is Wingtack 95?
Wingtack 95 is a legacy aliphatic C5 petroleum hydrocarbon resin used as a tackifier. Despite the grade name, available product data reports a typical Ring-and-Ball softening point of approximately 98°C, not an exact 95°C release value. The published description identifies a light-yellow resin used in hot-melt and solvent-borne PSAs, hot-melt adhesives, sealants, road-marking compounds, coatings, and rubber processing.
The archived Wingtack 95 product record reports the aliphatic C5 chemistry and 98°C typical softening point. A published Cray Valley hydrocarbon-resin guide also lists 98°C. These public figures define the comparison benchmark; procurement should rely on the buyer’s retained Wingtack 95 specification and control sample.
Wingtack 95 vs MR-C5110 — typical values
Typical values and selection characteristics — screening guidance only, not a drop-in-equivalence statement. Confirm the current MR-C5110 TDS, test methods, agreed limits, and lot COA before commercial approval.
| Comparison point | Wingtack 95 published benchmark | Milorez MR-C5110 |
|---|---|---|
| Resin family | Aliphatic C5 petroleum hydrocarbon resin | Aliphatic C5 hydrocarbon resin |
| Ring-and-Ball softening point | About 98°C typical | 110°C nominal |
| Appearance | Public data describes a light-yellow solid resin | Light-yellow granules; confirm current sample |
| Relative selection position | Standard-softening C5 tackifier | Higher-softening C5 screening option |
| Likely formulation effect | Established tack, peel, and cohesion balance depends on recipe | May shift the balance toward cohesion and heat response |
| Equivalence status | Comparison benchmark | Comparable alternative requiring reformulation |
The common C5 chemistry makes MR-C5110 relevant, but the 12°C difference in nominal softening point is material. It can affect blend viscosity, wetting, open time, low-temperature tack, shear, and heat resistance. Color values should be compared only when both suppliers use matched sample preparation and test methods.
PSA substitution guidance
For SIS, natural-rubber, synthetic-polyisoprene, or other compatible PSA systems, prepare a fresh incumbent control and a mass-for-mass MR-C5110 screening batch. Do not call that first batch a final formula. Hold polymer, oil, antioxidant, mixing history, coat weight, substrate, and conditioning constant so the resin effect is visible.
Measure blend clarity, viscosity at coating temperature, loop or rolling-ball tack, 180° peel, static shear, SAFT or the applicable heat test, and low-temperature performance. MR-C5110’s higher softening point may increase cohesion while reducing quick wetting or aggressive tack. If that occurs, evaluate resin loading, process temperature, or plasticizer balance one variable at a time.
Hot-melt adhesive substitution guidance
For hot melts, compare melt homogeneity, pump and coating viscosity, open time, set speed, substrate wetting, green strength, final bond, and heat aging. Run tests on the real paperboard, film, nonwoven, foam, or coated substrate; neat-resin values cannot predict interfacial adhesion.
Check the failure mode as well as the headline strength. A change from cohesive to adhesive failure, or from fiber tear to clean release, can reveal a compatibility or wetting problem that a single numerical result misses. After laboratory approval, confirm the candidate under production mixing and application conditions.
Free-sample qualification process
- Send the benchmark. Provide the Wingtack 95 specification, polymer, formulation role, resin loading, process temperatures, substrate, and acceptance tests.
- Review the gap. Milorez confirms the current MR-C5110 data and highlights the higher softening-point position before sampling.
- Test a free sample. Compare the control and candidate using matched raw materials, batch size, coating conditions, and conditioning.
- Confirm supply. After qualification, agree the specification, packing, destination, and schedule. Commercial MOQ is 1 × 20’ FCL.

Frequently asked questions
Is MR-C5110 a drop-in Wingtack 95 equivalent?
No. It is a separate Milorez grade and a comparable alternative for formulation screening.
Why is the softening-point difference important?
Higher softening point can change melt viscosity, wetting, tack, cohesion, set behavior, and warm-temperature performance.
Can I approve MR-C5110 from the TDS alone?
No. TDS comparison narrows candidates; the complete adhesive and intended substrate determine approval.
What information should I send with a sample request?
Send the incumbent specification, polymer, full test recipe or resin loading, processing window, substrates, pass/fail criteria, annual demand, and destination.
What if my benchmark is aromatically modified Wingtack 86?
Screen low-aromatic MR-5910 instead and review the C5/C9 copolymer resin guide. For Wingtack 95-type aliphatic C5 work, review MR-C5110 and request a free sample.
Frequently asked questions
What is Wingtack 95?
Wingtack 95 is a legacy aliphatic C5 petroleum hydrocarbon tackifier. Public product data describes a light-yellow resin and reports a typical Ring-and-Ball softening point of about 98°C.
Is MR-C5110 a drop-in equivalent to Wingtack 95?
No. MR-C5110 is a comparable aliphatic C5 candidate, but its nominal 110°C softening point is higher than the published Wingtack 95 benchmark, so reformulation and complete adhesive testing are required.
What can change when moving to MR-C5110?
Its higher softening point may support cohesion and warm-temperature performance, but may also raise melt viscosity or reduce wetting and low-temperature tack. The outcome depends on the complete formulation.
Which tests belong in a Wingtack 95 alternative trial?
Compare compatibility, melt viscosity, tack, peel, static shear, heat resistance, low-temperature performance, aging, and the bond failure mode on the intended substrate.
Can I request a free MR-C5110 sample?
Yes. Milorez offers a free sample for formulation evaluation. Commercial supply has a minimum order of one 20-foot full container load.
