描述
Xylan 8843 is a solvent-based, FEP-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.
Xylan 8843 is closely related to Xylan 8840, sharing the same FEP-based formulation that provides very good nonstick and abrasion resistant properties. Like Xylan 8840, it is available as a single-coat finish, simplifying the coating process while delivering outstanding nonstick release and durability.
The coating is part of the Xylan 8800 Series, which is applied to metal by conventional air spray or coil-coating techniques and is noted for its excellent nonstick properties. Xylan 8843 is registered for use on aluminum, aluminum alloys, and steels that are permitted for contact with food products and food media.
Typical applications include fasteners (bolts, nuts, stud bolts), industrial components, and food processing equipment requiring excellent release properties, abrasion resistance, and food-contact compliance.

Processing Guidelines for Xylan 8843 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 coil coating |
| Curing | High-temperature cure; follow manufacturer specifications |
| 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.
Single-Coat Application: Xylan 8843 is available as a single-coat finish, simplifying the coating process.
Food-Contact Compliance: For food-contact applications, ensure the coating is applied to approved substrates (aluminum, aluminum alloys, steels) per registration requirements.
Curing: High-temperature cure required. 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.
