Many installers assume:
“All Paint Protection Films are mostly the same.”
But this is only true in mild climates.
Once exposed to:
-
High UV (California, Arizona, Texas, Australia)
-
Humidity + Salt Air (Florida, Gulf Coast, Southeast Asia)
-
High Surface Heat (black cars, outdoor parking, sunny states)
PPF durability varies dramatically.
This is why two cars can have the same PPF, but look very different after 12 months — depending on climate.
What Hot Climates Do to PPF
| Stress Factor | Effect on Film | Symptoms Customers Notice |
|---|---|---|
| UV Radiation | Breaks down polymer bonds | Yellowing / Dull appearance |
| Heat | Accelerates adhesive oxidation | Haze / Edge lift / Glue marks |
| Infrared Radiation | Weakens top coat elasticity | Swirl marks no longer self-heal |
| Thermal Cycling | Expands & contracts film | Micro-cracking / Orange peel |
Think of it like this:
Heat + UV = Aging Accelerator
So in hot regions, a “3-5 year film” may degrade in 1-2 years.
What Coastal Climates Do to PPF
| Stress Factor | Effect on Film | Customer Complaint |
|---|---|---|
| Salt Spray | Chemical surface attack | Loss of gloss / “matte haze” |
| Humidity | Water absorption into adhesive | Cloudiness from inside |
| Acidic rain | Etches top coat | Stains & watermark retention |
This is why Miami installers complain more about haze, and Los Angeles installers complain more about yellowing.
Different climates = different failure modes.
How to Select PPF for Hot or Coastal Markets
✅ 1. TPU Must Be 100% Aliphatic
Aromatic TPU turns yellow fast under UV.
Aliphatic TPU remains optically clear.
TPU reference suppliers (authoritative, non-marketing links):
https://www.lubrizol.com/Engineered-Polymers
https://www.covestro.com/
https://www.basf.com/
Ask your supplier:
“What is your TPU base resin manufacturer and grade code?”
If they can't answer → do not sell that film in sunny regions.
✅ 2. Adhesive Must Be Anti-Yellowing and Non-Migrating
The adhesive, not the TPU, is responsible for:
-
Haze
-
Milky appearance
-
Internal clouding
Low-grade acrylic oxidizes in humidity = haze guaranteed.
Preferred specification:
-
Ashland optical-grade anti-yellowing acrylic adhesive

✅ 3. Top Coat Must Use HALS UV Stabilizers
HALS = Hindered Amine Light Stabilizers
These protect the top coat from UV-induced brittleness.
| Without HALS | With HALS |
|---|---|
| Top coat dries + cracks | Stays flexible and self-healing |
| Dirt sticks harder | Hydrophobic performance lasts longer |
| Gloss fades | Mirror gloss retention is stable |
If a film loses its self-healing ability in 6 months, it is missing HALS.
✅ 4. Ask for Q-SUN UV Test Report (ASTM Standard)
This test simulates years of sunlight exposure.
Standard reference:
https://www.astm.org/d1148-13.html
Look for:
ΔYI ≤ 1.2 after 3000 hours
If test not available → The supplier doesn't know how long their film lasts.
How HIGHCOOL PPF Is Engineered for These Climates
| Layer | HIGHCOOL Specification | Climate Benefit |
|---|---|---|
| TPU Base | 100% Aliphatic TPU from Wanhua / Covestro / BASF / Lubrizol | Prevents yellowing in strong UV |
| Adhesive | Ashland Optical-Grade Anti-Yellowing Acrylic | No haze in humidity / heat |
| Top Coat | Nano Hydrophobic + HALS UV Stabilized | Maintains gloss & self-healing |
| Warranty | 10-Year Anti-Yellowing | Real durability, not marketing |
This is why HIGHCOOL is used in:
-
California (UV)
-
Texas (heat)
-
Miami (salt air)
-
Middle East (extreme sunlight)
For Installers & Distributors, the Business Advantage Is Clear
Choosing climate-ready automotive protection film reduces:
| Risk | Business Impact |
|---|---|
| Yellowing claims | Protects your reputation |
| Haze complaints | No free re-installs |
| Top coat failure | Less labor loss |
| Customer dissatisfaction | More referrals & upgrades |
Selling the right film = more profit consistency.
