Corrosion Protection and Stone Chip Prevention: Innovation and Sustainability
A detailed article dated July 11, 2024, describes the problem of stone chips in the underbody and discusses the need for effective protection. This article highlights how stone chips not only impair a vehicle’s aesthetic appearance but can also compromise its structural integrity. This leads to higher maintenance costs and a shorter vehicle lifespan.
In the following, we will first introduce categories of stone chip protection products and then discuss the features necessary for effective protection.
PFINDER Products for Rockfall Protection
Water-based anti-corrosion coatings
These paints are ideal for direct-to-metal applications and floor protection. They dry quickly and offer excellent adhesion when applied directly to metal. The paints meet the requirements of the stone chip test according to DIN EN ISO 20567-2 on steel, aluminum, and zinc-passivated surfaces. This makes them an excellent choice for protection against intermittent stone-chip exposure and, consequently, for other partially exposed vehicle parts.
High-Performance Protective Coatings
These products offer high mechanical strength and excellent water resistance. They are specifically designed to provide stone-chip protection and meet the most stringent requirements of the stone-chip test according to DIN EN ISO 20567-1 B. They are ideal for use on electrocoated or otherwise painted surfaces, as well as on light metals and non-ferrous metals.
Over-paintable anti-corrosion coatings
In addition to excellent corrosion protection, these water-based coatings also offer good stone-chip resistance in accordance with DIN EN ISO 20567-1 B. They are available in both clear and black finishes and feature fast drying times and the ability to be painted over.
Benefits of PFINDER Solutions
Effective Stone Chip Protection
The permanently elastic protective films absorb the energy from stones and prevent surface damage. This is particularly important for vehicles that regularly travel on rough or unpaved roads. The high mechanical resistance of the coatings ensures that the vehicle’s surface remains undamaged even in the event of a severe impact.
Comprehensive Corrosion Protection
The seamless coating prevents the penetration of moisture and salts, the main causes of rust. This barrier effect is crucial for extending the service life of vehicle chassis and metal components. By preventing corrosion, the vehicle’s structural integrity is preserved, leading to lower maintenance costs in the long term.
Chemical Resistance
The protective coating is resistant to many chemical substances that may be present in industrial or agricultural environments. This protects vehicles not only during everyday use but also in more demanding industrial applications. Its chemical resistance ensures that the protective coating remains intact even in harsh environments.
Flexibility & Liability
Despite their durability, the films remain elastic, which means they do not crack or peel even when exposed to temperature fluctuations and mechanical stress. This elasticity ensures long-lasting adhesion and protection even under dynamic loads. The coatings’ fast drying time and overpaintability offer additional advantages for application and maintenance.
