PPG (NYSE:PPG) today announced the introduction of PPG PRIMERON^TM Optimal zinc epoxy powder primer. The patent-pending product is formulated with an optimized amount of zinc, providing better transfer efficiency than standard zinc-rich primers and corrosion protection that meets rigorous ISO C5 corrosivity specifications for use in high humidity and aggressive environments.

PPG Primeron Optimal primer has a much lower specific gravity than standard zinc-rich primers (2.0 vs. 3.6), making it less dense and easier to apply. With a transfer efficiency of 85%, about half as much product is needed compared to a standard zinc-rich primer, saving costs and enhancing sustainability. Additionally, PPG Primeron Optimal primer is made without solvents that release volatile organic compounds (VOCs).

“Corrosion protection is a decisive factor in the durability of a part and one of the most significant challenges for the coating industry,” said Paul Bradley, PPG manager, product development, Industrial Coatings. “PPG Primeron Optimal primer offers improved adhesion and corrosion resistance, even in coastal environments, and has a better overall balance of properties than traditional zinc-rich primers.”

Additional benefits include exceptional edge, face and scribe corrosion resistance, and excellent adhesion on both smooth and blasted steel for a strong bond that resists peeling, chipping and degradation. In lab testing, the primer surpassed 10,000 hours of salt spray performance on blasted steel. It is engineered for use on steel, hot-dip galvanized steel, metallized steel and aluminum, and is suitable for a wide range of applications, including trailers, gas tanks, pipes, automotive parts and machinery.

“PPG Primeron Optimal primer is a significant leap forward in corrosion protection and illustrates PPG’s commitment to sustainably advantaged solutions and powder coating innovations,” said Shelley Verdun, PPG business manager, powder coatings, Industrial Coatings.

The sustainability benefits include reduced waste and material usage. PPG Primeron Optimal primer can be gelled (partially cured), or used in a two-coat, one-bake process, yielding quicker, more sustainable and energy-efficient finishing that reduces greenhouse gas emissions by up to 50%.

PPG Primeron Optimal zinc epoxy primer is part of the company’s new PPG Primeron powder primer series, designed to provide high corrosion resistance for a wide range of applications and specific requirements depending on end use, operating environment and substrate. The product portfolio, which includes solutions in epoxy, polyester and epoxy polyester chemistries, comprises:

• PPG Primeron Optimal: Optimized zinc content delivers robust corrosion protection, higher transfer efficiency and a better overall balance of properties than standard zinc-rich primers.
• PPG Primeron Legacy: A traditional zinc-rich primer offering the strongest corrosion protection.
• PPG Primeron Auto: Engineered for layered production for automotive and specialty markets.
• PPG Primeron Edge: Offers best-in-class corrosion protection for substrates with sharp edges; optimized for degassing substrates, the effective release of bubbles from the coating during the curing process.
• PPG Primeron Versa: A versatile primer that offers strong corrosion protection for a wide range of substrates, including aluminum.
