Conversion Coatings

Whether you’re processing steel, galvanized substrates, aluminum, or mixed metals, our team works with you to select the right chemistry for your application, equipment configuration, and performance requirements. Our conversion coating technologies are engineered to perform reliably in spray, immersion, and wand applications while helping customers achieve their quality and operational efficiency goals.

Factors such as substrate type, washer design, operating temperature, contact time, overflow rates, and production interruptions all influence pretreatment performance. MetaLube evaluates your process requirements and finished-product expectations to recommend the most effective conversion coating technology for your operation.

A properly managed conversion coating process can provide the following benefits.

  • Improve salt spray performance and other accelerated corrosion testing
  • Reduce coating failures and warranty concerns
  • Achieve improved environmental compliance
  • Reduce energy and operational costs
  • Provide consistency from the pretreatment process

Zirconium conversion coating technologies have quickly become the preferred alternative to traditional phosphate systems in many metal finishing processes. This technology greatly reduces maintenance and energy costs while providing superior paint adhesion and corrosion control.

Benefits include:

  • Phosphate-free formulations
  • No regulated heavy metals
  • Energy-efficient operating temperatures
  • Reduced sludge generation
  • Lower maintenance requirements
  • Suitable for spray, immersion, and wand applications

MetaLube offers a comprehensive range of iron phosphate technologies designed to meet a wide variety of processing and performance requirements.

Our formulations are available in detergent-bearing and non-detergent options. They can be optimized for multistage or smaller, compact washer configurations. We offer these technologies for spray and immersion applications.

Benefits include:

  • Enhanced paint adhesion
  • Low-temperature operating capabilities
  • Flexible process integration
  • Easy bath control and maintenance
  • Compatible with spray, immersion, and pressure-wand applications

Your pretreatment process is the foundation of a durable, high-quality finish. MetaLube’s Seal Rinse technologies are designed to enhance paint adhesion, improve coating uniformity, and provide the corrosion protection needed to meet demanding performance standards.

Applied during the final stage of the pretreatment process, these technologies help improve long-term coating performance and reduce the risk of premature coating failure.

Benefits include:

Improved salt spray performance
Enhanced corrosion resistance
Increased paint durability
Additional flash-rust protection before painting
Compatible with with spray and immersion systems
