Advantages of PPG-PVDF Paint Over Other Coatings in Aluminum Exterior Curtain Walls

2025-11-25

Advantages of PPG-PVDF Paint Over Other Coatings in Aluminum Exterior Curtain Walls

1. Introduction

PPG-PVDF (Polyvinylidene Fluoride) paint has become the benchmark for high-end aluminum exterior curtain walls, outperforming conventional coatings such as polyester (PE), acrylic, and polyurethane (PU) in key performance indicators. This article compares PPG-PVDF with other paints through classified analysis and data tables, highlighting its unique advantages in architectural applications.

2. Superior Weather Resistance: Adaptable to Extreme Environments
