english Will stone protective film lose its effectiveness in humid environments
2025-08-01
Effects of Humidity on Stone Protective Films
1. Observe Changes in the Adhesive Layer
Humid environments can cause the adhesive layer of the protective film to absorb moisture, softening or reducing its adhesion. If the adhesive layer loses contact with the stone surface, it may cause the protective film to warp or hollow, compromising its protective effectiveness.
Key Observations:
- Adhesive softening in high humidity
- Potential warping or hollowing
- Risk of chemical changes in low-quality adhesives
2. Inspect the Film Structure
Water vapor can penetrate the interior of the protective film. If the film material is not water-resistant, delamination and cracking may occur. Edges are particularly susceptible to moisture erosion, losing their integrity.
3. Evaluate Protective Performance
When a protective film is damaged by moisture, its core properties, such as scratch resistance and stain resistance, are significantly reduced. Moisture can carry stains into the gaps between the protective film and the stone.
| Performance Aspect | Dry Conditions | Humid Conditions |
|---|---|---|
| Adhesion Strength | High | Reduced by 30-50% |
| Edge Integrity | Stable | Compromised |
| Stain Resistance | Excellent | Moderate to Poor |
4. Considering Fit Stability
If there are tiny cracks in the stone surface, moisture from humid environments may penetrate through these cracks, creating peeling forces between the protective film and the stone.
Stability Factors:
- Peeling forces from temperature fluctuations
- Risk of large-area peeling
- Loss of protective effect
5. Identifying Material Differences
High-quality stone protective films typically utilize highly waterproof materials and adhesive layers, and undergo special processing to provide resistance to humid environments.
