Скачать или смотреть Performance Test of KDPPF High Anti Stain PPF and Conventional PPF

Test Methodology and Process
Sample Preparation
KDPPF High Anti-Stain PPF: Utilizes molecular cross-linked topcoat technology, which enhances surface density and optimizes hydrophobic/oleophobic properties.
Conventional PPF: Features a standard coating structure with lower molecular density and lacks specialized anti-stain treatment.
Testing Procedure
Step 1: Oil-based marker pens (containing toluene solvent) were used to write identical marks on both PPF surfaces.
Step 2: Marks were left undisturbed for 10 minutes to simulate real-world contamination.
Step 3: Surfaces were wiped with alcohol-soaked microfiber cloths using uniform pressure.
Test Results Comparison
Criteria KDPPF High Anti-Stain PPF Conventional PPF
Post-Wipe Residue No visible residue; surface remains smooth Yellow stains persist
Anti-Permeability Toluene solvent blocked by dense coating Solvent penetrates base layer
Hydrophobic Performance Strong hydrophobicity prevents liquid adhesion Weak resistance leads to watermarks
Technical Analysis
KDPPF High Anti-Stain PPF
The nano-scale cross-linked topcoat creates a tightly packed structure, minimizing molecular gaps and blocking contaminant infiltration.
Hydrophobic/oleophobic properties reduce adhesion, while self-healing functionality mitigates chemical corrosion.
Conventional PPF
Poor solvent resistance allows toluene to dissolve the coating and penetrate the TPU base, causing permanent yellowing.
Absence of anti-stain additives results in physical adsorption of oily contaminants.
Conclusion
KDPPF’s advanced coating technology demonstrates superior anti-stain performance compared to conventional PPF, aligning with industry demands for corrosion resistance and contamination prevention. The limitations of conventional PPF highlight the critical role of coating engineering in long-term durability.
