Water-Based Soft-Touch Varnish for Paper and Treated Film
Model 24-10-33 is a water-based functional surface varnish for a soft-touch surface and uniform matte appearance on paper, paperboard, and verified treated film. Final feel and appearance must be confirmed with actual samples.
What this coating is
A tactile surface coating, not a generic matte OPV
Model 24-10-33 is a water-based functional surface varnish for creating a soft-touch surface and uniform matte appearance. The feel is the primary product job; actual feel and appearance are approved by sample, not by a universal claim.
The water-based soft-touch polymer system can be evaluated on paper, paperboard, treated BOPP, pearlized BOPP, and other verified treated films. The same product can feel different when substrate absorbency, surface treatment, underlying ink, coating delivery, drying, cooling, or post-processing changes.
JLJ Coat coordinates international sales enquiries, product matching and sample discussions with the production and technical teams. Formal production still requires validation using the actual substrate, underlying ink, coating method, coating amount, drying path, pressure, and downstream process.
Application methods
Coat, dry, cool, then approve the actual sample
Flexographic, gravure, roller, and offline coating are TDS-backed methods. Delivery, coating amount, speed, temperature, airflow, exhaust, and cooling remain machine- and substrate-dependent.

Factors affecting soft-touch results
The finish is a complete surface-and-process system
Compare one controlled change at a time. A different feel or matte appearance does not by itself identify the root cause.
Surface treatment
Treated side, treatment age, wetting, contamination, slip-additive migration, and any primer or film coating.
Underlying ink or coating
Ink chemistry, cure or drying state, residual additives, coverage, smoothness, and compatibility with the soft-touch layer.
Coating amount
Delivered wet film, coverage uniformity, target sample, and whether the surface is under- or over-applied.
Anilox or roller delivery
Cell or roller condition, transfer uniformity, metering, pressure, speed, circulation, and foam introduction.
Drying and cooling
Zone sequence, airflow, exhaust, web temperature, residual water, film formation, and cooling before handling.
Stacking or rewinding pressure
Surface temperature, elapsed time, roll or stack pressure, dwell, storage orientation, and contact surfaces.
Post-processing
Rubbing, folding, die-cutting, stamping, printing, coding, gluing, laminating, transport, and the acceptance method.
Common trial problems
Record the defect before changing the coating or process
The table lists possible contributing factors, first checks, and evidence to record. It does not promise that any one adjustment will solve the problem.
| Observed problem | Possible contributing factors | First checks | Evidence to record |
|---|---|---|---|
| Weak tactile effect | Low delivered film, absorbent substrate, underlying surface, incomplete film formation, or target-sample mismatch. | Compare actual coating delivery, substrate lot and absorbency, underlying print, drying and cooling, and an approved reference. | Record labeled drawdowns or press samples, delivery setup, speed, temperatures, airflow, coating-side identification, and feel observations after cooling. |
| Uneven matte appearance | Non-uniform transfer, foam, poor wetting, substrate variation, ink coverage, contamination, or uneven drying. | Map the pattern against anilox or roller width, printed areas, substrate direction, dryer zones, and surface cleanliness. | Keep full-width samples and photos with machine direction, location, material lot, delivery setup, and drying conditions marked. |
| Rough or dry feel | Surface absorption, insufficient leveling, delivery pattern, premature drying, contamination, or mismatch between feel target and sample. | Compare coated and uncoated material, surface smoothness, transfer uniformity, open time, dryer sequence, and the physical target. | Record substrate, print surface, magnified photos if available, delivery condition, time to drying, and feel comparison after conditioning. |
| Tackiness | Incomplete water removal or film formation, excessive delivered film, incompatible underlying layer, high roll or stack temperature, or insufficient cooling. | Check drying zones, airflow, exhaust, speed, surface temperature, coating delivery, cooling, and time before handling. | Record when tack first appears, temperature by stage, pressure and dwell, affected surfaces, material lots, and retained samples. |
| Blocking | Residual moisture, warm stacking or rewinding, pressure, high delivered film, incompatible surfaces, or insufficient conditioning. | Reproduce the contact pair and compare drying, cooling, elapsed time, pressure, roll or stack condition, and surface orientation. | Record contact sides, time, temperature, pressure, storage position, peel appearance, transfer marks, and acceptable comparison samples. |
| Pinholes | Poor wetting, entrained air, foam, contamination, substrate pores, surface additives, or delivery interruption. | Inspect the uncoated surface, mixed coating, circulation, filter, transfer element, and where pinholes first appear. | Record defect size and distribution, treated side, surface cleanliness, mixing and circulation history, filter, speed, and photos by process stage. |
| Poor adhesion | Wrong film side, inadequate or aged treatment, contamination, incompatible ink or coating, incomplete drying, or post-process stress. | Identify the failing interface and compare treated side, surface condition, underlying layer, drying, cooling, conditioning, and test method. | Record material supplier and lot, treatment data if known, marked sides, failure-interface photos, test timing, method, and downstream exposure. |
| Loss of effect after rubbing | Target-sample difference, incomplete film formation, delivered-film variation, substrate or ink interaction, conditioning, rubbing method, or downstream abrasion. | Compare pre- and post-rub samples with the stated method, load, cycles, conditioning time, contact material, and real handling route. | Record the full test method and photos, sample age, coating and drying conditions, affected area, and an acceptable reference; no rub level is guaranteed. |

FAQ
24-10-33 soft-touch varnish questions
What is model 24-10-33 designed to do?
Model 24-10-33 is a water-based functional surface varnish intended to create a soft-touch surface and uniform matte appearance. The resulting feel and appearance must be confirmed with the actual substrate, underlying ink, coating method, coating amount, drying, cooling, and post-processing conditions.
Which substrates can be evaluated with this soft-touch varnish?
Paper, paperboard, treated BOPP, pearlized BOPP, and other verified treated films can be evaluated. Film trials must identify the treated side and confirm surface condition, wetting, adhesion, and the complete downstream process.
Which coating methods are relevant?
The first-party TDS identifies flexographic coating, gravure coating, roller coating, and offline coating. The actual delivery setup, coating amount, machine speed, drying path, and result still require a controlled trial.
Are the viscosity, pH, and drying values guaranteed production specifications?
No. Viscosity of 50 ± 5 seconds using Ford Cup No. 4 at 25°C and pH of 7.0–8.0 are typical control information. The 80–110°C range is a trial starting point, not a guaranteed drying temperature or machine setting.
How should a target soft-touch effect be approved?
Compare coated samples made with the intended substrate, underlying ink or coating, delivery setup, coating amount, drying and cooling, stacking or rewinding pressure, and post-processing. Record the accepted sample and conditions before production approval.
What information is needed for a sample discussion?
Send the substrate and treated side, underlying ink or coating, coating process, anilox or roller setup, machine speed, drying setup, target feel and appearance, post-processing, current sample or defect photos, and whether physical samples are available.
Is model 24-10-33 approved for regulated packaging applications?
Regulated applications require model-specific SDS, test reports and compliance documents. This page does not claim that those documents are available or that any regulated use is approved.
Limitations and regulated-use notice
Approve the real surface and process, not a generic claim
This page does not guarantee soft-touch level, gloss or matte value, rub resistance, adhesion, drying temperature, machine speed, packaging, transport classification, environmental status, or regulated-use suitability. Solid content remains model-dependent and is not published. Regulated applications require model-specific SDS, test reports and compliance documents; this page does not imply that those documents are available.
