描述
Xylan 5420 is a waterborne, PTFE-based dip-spin fastener coating from Whitford Corporation (now PPG), part of the Xylan® 5000 Series . As an authorized distributor and trader, we supply genuine materials with full traceability and direct access to official technical documentation .
The Xylan 5000 Series was developed in the early 1980s for the automotive industry with the goal of protecting small components from corrosion using the properties of fluoropolymer coatings at a fraction of the cost of spray-applied materials . The coating is designed for application by a dip-spin or dip-coating centrifugation technique, achieving a transfer efficiency of nearly 99.9% .
Unlike Xylan 5230 (solvent-borne black automotive fastener coating), Xylan 5420 is a waterborne/VOC compliant product with a VOC content of less than 3.5 lbs/gal (420 g/L), intended to offer an environmentally acceptable alternative to solvent-borne materials . It is chrome-free and free of all restricted heavy metals, meeting EU ELV and RoHS regulations .
Xylan 5420 is specifically formulated for small fasteners and hardware, providing excellent corrosion and chemical resistance comparable to Xylan 5230 . The coating reduces chipping, increases adhesion, and offers cost savings of up to 25% compared to zinc flake coatings . It resists road salt, acid rain, and environmental corrosion, making it a preferred choice for automotive fasteners .

Processing Guidelines for Xylan 5420 Coating
| Step | Process |
|---|---|
| Surface Preparation | Degrease → phosphate pretreatment recommended for carbon steel fasteners |
| Coating Preparation | Low-speed mechanical stirring; dilute with deionized water only |
| Application | Dip-spin (centrifugal coating) – ideal for small fasteners; or conventional spray |
| Curing | 200–230°C for 10–20 minutes (substrate temperature) |
| Storage | Store in original, sealed containers in a cool, dry place away from direct sunlight. Shelf life: 18 months |
Critical Processing Warnings:
Surface Preparation: Phosphate pretreatment is recommended for carbon steel to maximize corrosion resistance .
Coating Mixing: Use only deionized water for dilution. Never use tap water, as minerals and impurities can destabilize the coating.
Dip-Spin Process: The dip-spin method achieves high transfer efficiency and is the recommended application method for high-volume small fastener production .
Curing: Cure at 200–230°C for 10–20 minutes. Cure time depends on part mass and oven characteristics. Always verify with test pieces .
Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.
