Pre-Treatment Chemicals
Optimizing Surface Preparation for Superior Coatings
Pre-treatment chemical applications are crucial to surface preparation, ensuring that coatings adhere properly to metal and other substrates while enhancing corrosion resistance and durability. At Associated Finishing, we provide a range of pre-treatment chemical solutions tailored for industrial, automotive, aerospace, and custom applications.
With advanced pre-treatment processes, including zirconium, iron phosphate, and trivalent chromium coatings, we prepare parts for powder coating, liquid coating, and other finishing applications. Our state-of-the-art wash systems ensure thorough cleaning, etching, and chemical bonding, creating a flawless foundation for high-performance coatings.
What Are Pre-Treatment Chemicals?
Pre-treatment chemicals are specialized cleaning and conditioning agents used before the application of coatings to:
- Remove dirt, grease, and oxides
- Improve paint and powder coating adhesion
- Enhance corrosion resistance
- Extend the lifespan of coatings
At Associated Finishing, our multi-stage pre-treatment systems ensure that parts receive the proper chemical treatment for optimal coating performance.
Iron Phosphate & Zirconium Treatments
Iron Phosphate & Zirconium Treatments
For steel, aluminum, and other metal components, we use iron phosphate and zirconium pre-treatment solutions to enhance coating adhesion and resistance to environmental wear. These processes:
- Clean and etch surfaces for better coating performance
- Improve durability in high-moisture and corrosive environments
- Are compatible with both powder and liquid coatings
Our Litchfield wash bay, measuring 25′ L x 10′ W x 9′ H, is designed to handle large and oversized parts, ensuring even coverage and thorough chemical application.
Multi-Stage Wash Systems for High-Volume Production
Our pre-treatment capabilities include:
- 6-stage in-line washer with extended cooling zone
- 5-stage in-line washer for large-capacity components
- 3-stage in-line washer for high-throughput production
- Offline washing system for specialized pre-treatment needs
Trivalent Chromium Pretreatment (TCP)
We offer trivalent chromium pre-treatment, an environmentally friendly alternative to traditional hexavalent chromate. This dip process forms a protective chemical film on metal surfaces, preventing oxidation and ensuring superior coating adhesion.
- Meets MIL-DTE 81706B & MIL-DTL 5541F standards
- Conforms to ASTM 3359 & 2559-9 specifications
- Fully RoHS-compliant for eco-friendly coating applications
- Provides long-lasting corrosion protection
Why Pre-Treatment Matters for Industrial Coatings
Improved Coating Performance
Pre-treatment chemicals create an optimal bonding surface, ensuring uniform adhesion and reducing the risk of peeling, chipping, or blistering over time.
Corrosion Protection
By applying phosphate, zirconium, or chromium coatings, metal parts gain enhanced corrosion resistance, preventing premature failure in harsh environments.
Consistent Quality Across High-Volume Production
Our automated wash systems provide repeatable, high-quality surface preparation, ensuring every part meets strict industry specifications.
