Description

Calcium Plumbate CAS NO 12013-69-3 is an inorganic compound primarily recognized for its role as a corrosion-inhibiting pigment. This material is valued for its ability to provide long-term protection to metal substrates, particularly steel, in harsh environments. It is a critical raw material for formulators in the protective coatings and anti-corrosion primer industries seeking to enhance product durability and performance.

Application

• Corrosion-Inhibiting Primers: A key active pigment in primers for steel structures, bridges, ship hulls, and industrial equipment.
• Marine & Offshore Coatings: Formulated into coatings that protect against saltwater spray and high-humidity conditions.
• Heavy-Duty Industrial Maintenance Paints: Used in paints for factories, chemical plants, and infrastructure exposed to corrosive atmospheres.
• Automotive Underbody Coatings: Provides rust prevention for vehicle chassis and components.
• Zinc-Rich Primer Modification: Can be used in conjunction with zinc dust to modify the galvanic and barrier protection properties.
• Pipeline Coatings: Employed in protective systems for oil, gas, and water transmission pipelines.
