描述
Xylan 4500 is a general-purpose, PTFE-based dry film lubricant coating from Whitford Corporation (now PPG). As an authorized distributor and trader, we supply genuine materials with full traceability and direct access to official technical documentation.
Xylan coatings, including Xylan 4500, are composite fluoropolymer systems that combine PTFE, PFA, or FEP with reinforcing resin systems to deliver low friction, wear resistance, and corrosion protection in a single thin-film application . The Xylan family of coatings is widely used across industries including food processing, manufacturing, petrochemical, aerospace, and automotive .
Xylan 4500 is designed for general-purpose industrial applications where controlled low friction, corrosion protection, and dry-film lubricity are required. Unlike lubricating oils or greases, Xylan provides a permanent dry-film lubricant that eliminates the need for reapplication in many applications . The coating can be applied as a thin film without significantly affecting part dimensions, making it suitable for precision components .

Important Notes on Typical Data:
Values listed are typical and sourced from manufacturer data sheets and industry references. They do not constitute binding product specification.
Batch-to-batch deviations may exist. For critical applications, validate performance with batch-specific COA certificate.
Final performance depends on substrate preparation, application method, and curing conditions.
Manufacturer official TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.
Processing Guidelines for Xylan 4500 Coating
| Step | Process |
|---|---|
| Surface Preparation | Degrease (acetone or isopropanol) → grit-blast (Sa2.5, Ra 1.5–4.0 μm) → optional phosphate or zinc pretreatment for steel |
| Coating Preparation | Low-speed mechanical stirring; dilute with recommended thinner or deionized water |
| Application | Spray (conventional, HVLP, or electrostatic), dip, or dip-spin coating |
| Curing | Follow manufacturer specifications; typically 200–400°C depending on formulation |
| Storage | Store in original, sealed containers in a cool, dry place away from direct sunlight. Shelf life: 18 months |
Critical Processing Warnings:
Surface Preparation: Proper surface preparation is critical for adhesion. Ensure surfaces are clean, dry, and properly roughened.
Curing: Cure temperature depends on formulation and substrate; part mass and oven characteristics determine exact time. Always verify with test pieces.
Coating Mixing: For waterborne grades, use only deionized water for dilution. Never use tap water, as minerals can destabilize the coating.
Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.
