PPG Industries Launches AQUACRON WSP Waterborne Shop Primers for Structural Steel Applications

PPG Industries has unveiled a new line of advanced waterborne shop primers designed specifically for structural steel applications. The newly introduced PPG AQUACRON® Waterborne Shop Primers (WSP) represent a significant step forward in coating technology, offering a combination of rapid curing, a smooth finish, and reduced volatile organic compound (VOC) emissions. This innovative primer system has been engineered to perform reliably across a wide range of climatic conditions, making it a versatile solution for steel fabrication facilities worldwide.

The PPG Aquacron WSP primers are intended to be applied in factory environments to protect structural steel components such as beams, purlins, joists, and framing systems. These elements are particularly vulnerable to flash rust and corrosion when exposed to moisture during storage or transportation, especially when materials are kept outdoors before installation at construction sites. By providing a durable protective layer, the primers help maintain the integrity of the steel during these critical handling stages.

One of the key features of the Aquacron WSP series is its water-resistant coating layer. This layer significantly reduces the need for extensive surface preparation, such as sandblasting, prior to applying a final topcoat or installing the steel components. As a result, fabricators and contractors can save considerable time and labor costs while also minimizing operational complexity. The simplified preparation process allows projects to progress more efficiently without compromising quality or durability.

According to Brian Smith, Business Manager for Liquid Coatings in the Industrial Coatings division at PPG Industries, achieving a formulation that combines lower VOC levels with faster drying times and improved surface quality represents a major advancement in waterborne primer technology. Traditional waterborne primers often require lengthy curing times—typically between 12 and 24 hours—and can sometimes develop surface defects that affect finish quality. These limitations have historically restricted their widespread use in high-volume fabrication operations.

The Aquacron WSP technology addresses these challenges by dramatically shortening curing times. Under standard heat conditions, the primer can cure in as little as two minutes, allowing steel fabricators to significantly increase production throughput. This rapid curing capability also reduces the amount of floor space required for drying and staging coated parts, enabling manufacturers to optimize facility layouts and improve operational efficiency. For large-scale fabricators handling high production volumes, these benefits translate into faster order fulfillment and improved cost-effectiveness.

In addition to its performance advantages, the new primer system aligns with growing environmental and regulatory requirements. The VOC emissions associated with the Aquacron WSP primers are comparable to those found in typical residential-grade paints, making them a lower-emission option compared with many conventional coatings. Furthermore, the primers remain stable across a wide range of temperature and humidity conditions, eliminating the need for climate-specific formulations. This adaptability simplifies product specification and sourcing while helping companies comply with increasingly strict emissions regulations.

The launch of the PPG Aquacron WSP series reflects the company’s broader commitment to developing sustainably advantaged coating solutions. By combining durability, efficiency, and environmental responsibility, the new technology aims to support steel fabricators in improving productivity while reducing their environmental footprint. Through innovations such as these, PPG Industries continues to expand its portfolio of high-performance coatings designed to meet the evolving needs of industrial manufacturing and construction sectors.
