No two paint lines are exactly alike. 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.
Zirconium Conversion Coatings
Zirconium technologies have become a preferred alternative to traditional phosphate systems because of their simplified operation, environmental advantages, and reduced energy requirements.
Benefits include:
- Phosphate-free formulations
- No regulated heavy metals
- Energy-efficient operating temperatures
- Reduced sludge generation
- Lower maintenance requirements
- Suitable for spray, immersion, and pressure-wand systems

- ZirPrep® PW – specifically designed for manual spray-wand applications
Iron Phosphate Conversion Coatings
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

Seal Rinse Technologies
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

- SilPrep
- MetaSeal® – acidic and alkaline seal rinse products
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.
A properly selected and controlled conversion coating can help:
- Improve paint adhesion and coverage
- Increase corrosion resistance
- Extend coating life and durability
- Reduce coating failures and warranty concerns
- Improve performance in salt spray and accelerated corrosion testing
- Support consistent production quality across varying operating conditions
Our conversion coating technologies are engineered to perform reliably in spray, immersion, and pressure-wand systems while helping customers achieve their quality and operational-efficiency goals.
