描述
Xylan 4430 is a low-friction, PTFE-based dry film 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 4430 is a member of the Xylan family of fluoropolymer coatings, which combine low-friction fluoropolymers (PTFE, PFA, or FEP) with reinforced resin systems to deliver lubricity, wear resistance, and corrosion protection . These coatings are designed to reduce friction, resist corrosion, and improve release or non-stick performance in industrial and commercial components .
Xylan coatings, including Xylan 4430, are commonly applied to fasteners, pumps, pistons, molds, dies, tubes, compressor parts, and cookware where low friction, corrosion resistance, or non-stick properties are required . In industrial environments, they are widely used in offshore oil production, process equipment, and food processing applications where surfaces must resist wear, corrosion, and material buildup .
This coating provides controlled low friction and reduces wear and energy consumption in machinery, improving the efficiency of moving parts . It also protects industrial and automotive components in corrosive environments, reducing maintenance costs and downtime . The coating is available in a wide range of colors .
Key Features of Xylan 4430 Coating

Chemical Resistance – Withstands exposure to acids, bases, solvents, hydraulic fluids, and jet fuels
-
Controlled Torque-Tension – Provides favorable torque values, reducing torque required to achieve desired preload tension
-
Dry-Film Lubricity – Provides lubrication without oils or greases, eliminating reapplication needs
-
Wear and Abrasion Resistance – Reinforced resin systems improve durability under sliding contact and repeated use
-
Non-Stick Performance – Prevents material buildup and eases cleaning
-
Substrate Versatility – Can be applied to metals, plastics, ceramics, and composites

Processing Guidelines for Xylan 4430 Coating
| Step | Process |
|---|---|
| Surface Preparation | Degrease → grit-blast (Sa2.5) → optional phosphate pretreatment for steel |
| Coating Preparation | Low-speed mechanical stirring; dilute with recommended thinner or deionized water |
| Application | Spray (conventional or HVLP), 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.
