PPG introduces PPG AQUACRON WSP shop primers series for structural steel

Waterborne formulation sets new benchmark for faster finishing, sustainability

PITTSBURGH--(BUSINESS WIRE)--PPG (NYSE:PPG) today announced the launch of PPG AQUACRON® Waterborne Shop Primers (WSP) for structural steel. This breakthrough technology is suitable for all climates and combines rapid curing with a smooth finish and low volatile organic compounds* (VOCs), delivering a balance of properties unmatched in existing waterborne primers.

PPG Aquacron WSP primers are factory applied to protect steel beams, purlins, joists and framing against flash rust and corrosion that may occur on job sites, especially when materials are stored outdoors. They feature a water-resistant layer that minimizes the need for sandblasting and surface preparation before top-coat application and installation, leading to substantial savings in time, labor and cost.

“Developing a lower-VOC, faster-drying formulation with a smoother finish and adaptable across environmental conditions is a benchmark achievement in waterborne primers,” said Brian Smith, PPG business manager, liquid coatings, Industrial Coatings.

Existing waterborne primers are slow drying, requiring 12-24 hours to fully cure, and prone to surface defects. With PPG Aquacron WSP primers, steel fabricators have a water-based, sustainably advantaged solution** that delivers a smoother finish and cures in just two minutes under standard heat. This represents an opportunity for high-volume operators to accelerate throughput and reduce space needed for drying and curing parts before shipping.

PPG Aquacron WSP primers have VOC emissions similar to those found in standard residential-grade paints and are stable under varying temperature and humidity. These features help steel fabricators comply with stringent emissions regulations and streamline product specification and sourcing by eliminating the need for climate-specific primers.

This innovation illustrates PPG’s commitment to sustainably advantaged solutions that deliver on durability, performance and efficiency. Click here to learn more about PPG’s sustainability initiatives.
