Hydrophilic TPU Paint Protection Film Buyer’s Guide: How to Select ECO G15

ECO G15 is a transparent, hydrophilic paint protection film designed for automotive paint. It combines an aliphatic polyether TPU base, high-gloss transparency, self-healing performance and a surface that allows water to spread more evenly.

This guide summarizes the product specifications, factory test data, intended applications and key purchasing considerations to help distributors, installers and professional buyers determine whether it fits their market.

ECO G15 hydrophilic TPU paint protection film

1. Product Positioning

ECO G15 is intended for buyers who want a clear PPF with a hydrophilic surface rather than a conventional water-beading finish. Its surface encourages water to spread into a more even layer, supporting easier cleaning and helping reduce visible water-spot residue.

The film is particularly relevant for vehicles used in rainy cities, polluted urban environments and industrial areas. Its low initial yellowness and transparent, high-gloss finish also make it a suitable option for white vehicles where film clarity is especially noticeable.

Climate consideration: The film has a relatively firm texture and is not recommended for extremely cold regions. Buyers should evaluate local climate conditions before selecting it for regional distribution or installation.

2. Product Specifications

Specification ECO G15
Product type Hydrophilic TPU paint protection film
Material Aliphatic polyether TPU (Covestro)
Color Transparent
Available nominal thickness 6.5 / 7.5 / 8.5 mil (165 / 190 / 215 μm)
Roll size 1.52 m * 15 m
Roll weight 12.5 kg

Confirm the required thickness option when ordering. The factory test values below are recorded for the tested ECO G15 sample and should not be interpreted as the nominal specification of every available thickness option.

3. Factory Test Data

The following data provides a technical reference for evaluating film structure, appearance, mechanical properties, adhesion, weathering resistance and self-healing performance.

Test Property Recorded Result
Total thickness 183 μm
Top film / release liner thickness 52 / 77 μm
Gloss 96.8 GU
Tensile strength 23.31 MPa
Elongation at break 345.11%
Elastic modulus 6.01 MPa
Peel force after 20 minutes / 24 hours 1613 / 1917 gf/in
QUV aging, 3000 hours (ΔE*ab < 2) Pass
Self-healing at 25°C 100%
How buyers should read the data: Gloss indicates the appearance of the tested film, while tensile strength, elongation and elastic modulus describe its mechanical behavior. Peel-force results show the recorded adhesion after two bonding periods. The QUV result is an accelerated-aging test result, not a statement of a specific outdoor service life.

4. Main Performance Features

Hydrophilic Surface

Instead of causing water to form pronounced beads, the hydrophilic surface allows it to spread more evenly. This supports easier routine cleaning and helps limit visible water-spot residue, making the film especially relevant for rainy or polluted environments.

Clear, High-Gloss Appearance

The transparent film is designed to preserve the appearance of the original paint rather than alter its color. The tested gloss value is 96.8 GU, supporting a bright, high-gloss finish.

Self-Healing Surface

The surface coating can repair fine scratches. Factory data records 100% self-healing at 25°C under the stated test conditions. Heat can be used to accelerate and enhance the recovery process.

Protection Against Road Debris

The TPU film provides a physical barrier between the paint and common road hazards, helping protect against stone chips and minor surface damage. It is intended for exterior automotive paint protection.

Stretch and Tear Resistance

The tested tensile strength of 23.31 MPa and elongation of 345.11% provide useful reference points for buyers assessing mechanical performance. The film is described as having a relatively firm texture while retaining high stretch and tear resistance.

UV and Aging Resistance

The product specification lists 99% UV rejection. It also passed a 3000-hour QUV aging test with ΔE*ab below 2 under the stated test condition, supporting its resistance to discoloration and aging.

Low Initial Yellowness

The aliphatic polyether TPU base has low initial yellowness, making film clarity easier to maintain visually on light-colored paint. This characteristic is particularly relevant when selecting PPF for white vehicles.

Lower Routine Appearance-Maintenance Requirements

Because the film provides a glossy protective surface, routine washing can help maintain its appearance without frequent waxing or ceramic coating. Actual maintenance needs will still depend on driving conditions, contamination and local water quality.

5. Choosing the Right Thickness

ECO G15 is available in three nominal thicknesses. Buyers should match the thickness to the intended market, installation requirements and desired protection level.

Nominal Option Metric Thickness Purchasing Consideration
6.5 mil 165 μm The thinnest available option; consider when a lower nominal thickness is required.
7.5 mil 190 μm The middle option for buyers seeking a balance within the available range.
8.5 mil 215 μm The thickest available option; consider when a higher nominal thickness is preferred.

Thickness alone should not be used to judge overall film quality. Buyers should also review gloss, stretch, adhesion, aging performance, surface characteristics and climate suitability.

6. Recommended Applications

  • White and light-colored vehicles: The low initial yellowness and clear TPU base are especially relevant where film color is easy to notice.
  • Rainy cities: The hydrophilic surface supports more even water spreading and easier cleaning.
  • Polluted urban areas: Suitable for city vehicles exposed to frequent surface contamination.
  • Industrial-area vehicles: Provides a removable protective layer over automotive paint.
  • Daily commuters: Helps protect frequently driven vehicles from minor scratches, road debris and routine environmental exposure.
  • High-gloss installations: Appropriate when maintaining a bright, transparent appearance is a priority.
Not the preferred choice for: Extremely cold regions, due to the product’s relatively firm texture. Climate suitability should be confirmed before bulk purchasing.

7. Self-Healing and Heat-Assisted Repair

The surface coating has a thermal self-healing function. Fine surface scratches may recover at room temperature, while controlled heating can accelerate and enhance the process.

  1. Clean the affected area so that no abrasive dirt remains on the surface.
  2. Apply warm water above 55-65°C or use a heat gun carefully.
  3. Heat the area evenly and avoid concentrating excessive heat in one location.
  4. Allow the coating to recover toward a smooth, even state.
Heat-assisted repair is intended for fine surface scratches in the coating. It should not be treated as a repair method for cuts, punctures, deep damage or film that has separated from the vehicle.

8. Buyer’s Pre-Order Checklist

Before placing an order, confirm the following details:

  • The required nominal thickness: 6.5, 7.5 or 8.5 mil.
  • The standard roll size of 1.52 m * 15 m.
  • Whether a hydrophilic finish matches the target customer’s preference.
  • Whether the local climate includes extreme cold conditions.
  • Whether the intended market prioritizes white-car compatibility, high gloss and low initial yellowness.
  • Whether the technical test data meets the project’s purchasing requirements.
  • That professional PPF installation tools and procedures are available.

9. Frequently Asked Questions

Is ECO G15 a hydrophobic or hydrophilic PPF?

It is a hydrophilic PPF. Water is designed to spread more evenly across the surface rather than form pronounced beads.

Is it suitable for white vehicles?

Yes. Its aliphatic polyether TPU base has low initial yellowness, making it particularly relevant for white and other light-colored vehicles.

Does the film self-heal without heat?

Factory data records 100% self-healing at 25°C under the stated test conditions. Warm water above 60°C or careful use of a heat gun can accelerate and enhance recovery.

Can heat repair deep cuts or punctures?

No. The self-healing function applies to fine scratches in the surface coating, not deep cuts, punctures or structural film damage.

Is this film recommended for extremely cold climates?

No. Because the film has a relatively firm texture, it is not recommended for extremely cold regions.

What is the roll size?

Each roll is 1.52 m wide and 15 m long, with a listed weight of 12.5 kg.

Does the 183 μm test result apply to every thickness option?

No. The product is offered in nominal thicknesses of 165, 190 and 215 μm. The 183 μm figure is the recorded total thickness of the tested ECO G15 sample.

10. Purchasing Summary
