描述
Xylan 8254 is a dark grey fluoropolymer-based primer 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 8254 is specifically formulated as a primer layer to enhance the adhesion of subsequent topcoats to metal substrates. It has been documented in testing on aluminum panels, where it demonstrated improved topcoat adhesion when compared to PAI-containing dispersions or coatings applied without primers. The primer is identified as “MOD” (modified) formulation, indicating it is an optimized version of the standard product.
Typical processing involves spray application with a spray gun pressure of 18 psi for the primer coat, followed by curing at 260°C for 15 minutes. The primer is designed for use under various fluoropolymer topcoats, including TF 5035 PTFE dispersions. Adhesion performance is verified using the tape test per ASTM D-3359-97 Method B.
Xylan 8254 is suitable for use on aluminum and other metal substrates, making it ideal for fastener applications, industrial components, and coating systems requiring reliable primer-to-topcoat adhesion.

Processing Guidelines for Xylan 8254 Coating
| Step | Process |
|---|---|
| Surface Preparation | Clean substrate; for aluminum: wipe with acetone after roughening |
| Primer Application | Apply Xylan 8254 by spray at 18 psi |
| Air Dry | Air dry at room temperature (approximately 22°C) for 15 minutes |
| Curing | Cure at 260°C (500°F) for 15 minutes |
| Cool Down | Cool to room temperature (20–22°C) after curing |
| Topcoat Application | Apply compatible topcoat (e.g., TF 5035) using same sprayer |
| 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. For aluminum, wipe with acetone after roughening.
Spray Application: Spray gun pressure should be set at 18 psi for the primer coat.
Curing: Cure at 260°C for 15 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.
