描述
Xylan 8840 is a solvent-based, FEP (fluorinated ethylene propylene)-based nonstick coating from Whitford Corporation (now PPG), part of the Xylan® coating family. As an authorized distributor and trader, we supply genuine materials with full traceability and direct access to official technical documentation.
Unlike Xylan 1010, 1014, or 1070 which use PTFE as the primary nonstick element, Xylan 8840 uses FEP instead of PTFE in its formulation. FEP (when correctly processed) provides even better nonstick properties than PTFE, making Xylan 8840 the coating with the best nonstick performance among all Xylan coatings currently in production.
Xylan 8840 is classified as a fluoropolymer/inorganic binder coating, specifically formulated for high-temperature applications. It delivers exceptional release properties with zero demolding force demonstrated in tire mold applications, making it ideal for demanding industrial environments including refinery service, high-temperature bolting, tire molds, and food processing.
The coating is available as a single-coat finish, simplifying application while delivering outstanding performance. It is food-contact acceptable and suitable for applications requiring FDA compliance.

Processing Guidelines for Xylan 8840 Coating
| Step | Process |
|---|---|
| Surface Preparation | Degrease (acetone or isopropanol) → grit-blast (Sa2.5, Ra 1.5–4.0 μm) → optional phosphate pretreatment for steel |
| Coating Preparation | Low-speed mechanical stirring; dilute with manufacturer-recommended solvent |
| Application | Spray (conventional or HVLP), dip-spin (for fasteners), or dip coating |
| Curing | 375–420°C (707–788°F) for 5–15 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: Proper surface preparation is critical for adhesion. Grit-blast to Sa2.5 grade with Ra 1.5–4.0 μm .
Curing: Xylan 8840 requires high-temperature curing at 375–420°C. Cure time depends on part mass and oven characteristics. Always verify with test pieces.
FEP Processing: FEP requires correct processing to achieve optimal nonstick properties. Follow manufacturer specifications carefully .
Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.
