Piccotac Equivalent: Compare 1095 and 1100

For a Piccotac 1095 or Piccotac 1100 replacement project, start by screening MR-C5100. It is Milorez’s closest equivalent candidate in the aliphatic C5, approximately 100°C softening-point class. MR-C5110 is a higher-softening C5 option when more heat response is required, while MR-5910 is a low-aromatic C5/C9 reformulation option—not a like-for-like Piccotac equivalent. None should be approved as a drop-in replacement without testing the complete adhesive.

What is the Piccotac resin series?

Piccotac became widely specified through Eastman’s former adhesives-resins portfolio. Eastman’s historical selection guide classifies Piccotac grades as aliphatic hydrocarbon resins and lists Piccotac 1095 and 1100 around the 95–101°C softening range.¹ Eastman completed the sale of its adhesives-resins business to Synthomer in 2022, so buyers should identify the exact incumbent grade and use a current data sheet rather than relying on a name alone.²

The current Piccotac 1095 data sheet describes a narrow-molecular-weight-distribution aliphatic C5 tackifier for adhesives, with 95°C Ring-and-Ball softening point, Gardner color 2, and 43°C glass-transition temperature. It lists compatibility with SIS, natural rubber, polyisoprene, butyl rubber, low-VA EVA, and several polyolefin elastomers.³

For the 1100 position, the current Piccotac 1100-E reference describes a low-molecular-weight aliphatic C5 resin for pressure-sensitive and hot-melt systems, with 100°C softening point, Gardner color 3, and 49°C glass-transition temperature.⁴ A suffix matters: do not assume 1100, 1100-E, 1100-N, or regional versions have matching specifications.

Typical values and selection positions — screening guide, not interchangeable sales specifications

Reference grade	Chemistry	Softening point	Color	Milorez selection
Piccotac 1095	Aliphatic C5	95°C typical	Gardner 2 typical	MR-C5100: closest first screen; assess the 5°C nominal shift
Piccotac 1100 / 1100-E reference	Aliphatic C5	100–101°C typical	Gardner 3 typical	MR-C5100: closest chemistry and softening-point position
MR-C5100	Aliphatic C5	100°C nominal	Gardner ≤5 typical	Primary comparable alternative
MR-C5110	Aliphatic C5	110°C nominal	Gardner ≤5 typical	Higher-softening reformulation route
MR-5910	Low-aromatic C5/C9 copolymer	Confirm current TDS	Confirm current TDS	Optional compatibility adjustment, not a direct equivalent

The table does not claim matching molecular-weight distribution, cloud points, antioxidant package, viscosity curve, color stability, or polymer compatibility. Request current Milorez data and agree the commercial specification before purchase. See the C5 resin guide and C5/C9 copolymer guide for the chemistry distinction.

Substitution by application

Pressure-sensitive adhesives and labels

In SIS- or natural-rubber-based PSAs, begin at the incumbent resin loading with MR-C5100. Compare blend clarity, coating viscosity, loop tack, 180° peel, shear holding power, and aged color. For labels, repeat testing on the actual facestock, release liner, and substrates at low and room temperatures. The PSA formulation guide explains why matching softening point alone cannot predict performance.

Hot-melt adhesives

For EVA, APAO, or polyolefin hot melts, record compatibility, melt viscosity at the real application temperature, open time, set speed, heat resistance, and thermal-aging color. MR-C5110 may support a higher-temperature target but can also raise viscosity or reduce low-temperature wetting. Trial MR-5910 only when controlled aromatic modification is technically justified.

A practical sample qualification process

1. Define the benchmark. Record the full Piccotac grade, suffix, lot COA, TDS revision, polymer, resin loading, oil, wax, antioxidant, and pass/fail targets.
2. Select the candidate. Start with MR-C5100 for 1095 or 1100. Add MR-C5110 or MR-5910 only when the formulation objective supports that change.
3. Run a controlled bench trial. Keep every component and process condition constant, then test neat-resin properties, blend compatibility, viscosity, tack, peel, shear, and aging.
4. Adjust one variable at a time. If needed, change resin loading, oil, wax, or candidate grade in documented steps.
5. Confirm scale-up. Validate coating or application behavior, finished-product performance, and an agreed purchase specification before a commercial shipment.

Frequently asked questions

What is the closest Milorez equivalent to Piccotac 1095?

MR-C5100 is the closest starting candidate by C5 chemistry and softening-point class. Its nominal value is 100°C versus 95°C typical for Piccotac 1095, so formulation qualification is required.

What is the closest Milorez equivalent to Piccotac 1100?

Start with MR-C5100. Verify the complete incumbent name and current TDS first because Piccotac 1100 variants and suffixes may differ.

Should I use MR-C5110 instead?

Only when a 110°C C5 grade supports the required heat or cohesion target. It is a higher-softening option, not the closest direct match.

When does MR-5910 make sense?

Use it as a low-aromatic C5/C9 reformulation candidate when broader aromatic affinity is needed. It is not chemically equivalent to aliphatic Piccotac 1095 or 1100.

Can I test a sample before ordering?

Yes. Samples are free for evaluation. Submit the polymer, incumbent grade, application, test targets, and destination; the commercial MOQ remains 1 × 20’ FCL.
