描述
Xylan 1391 is a solvent-based, high-build PPS/PTFE composite 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.
Unlike Xylan 1311 (abrasion-first, low PTFE), Xylan 1331 (high-lubricity, high PTFE), and other Xylan grades, Xylan 1391 is a high-build coating specifically designed for superior corrosion protection. The thicker film application provides enhanced barrier protection against aggressive environments while maintaining the chemical resistance and durability characteristic of the PPS/PTFE composite system.
The coating combines PPS (polyphenylene sulfide) , which provides excellent chemical resistance at elevated temperatures, bonding strength, and abrasion resistance, with PTFE for nonwetting and lubricating properties. The high-build formulation delivers enhanced corrosion protection, making it particularly suitable for downhole tools, valves, and oilfield components exposed to harsh chemical and corrosive environments.
Key Features of Xylan 1391 Coating
-
High-Build Formulation – Thicker coating film provides superior corrosion protection and barrier performance in aggressive environments
-
PPS/PTFE Composite System – Combines chemical resistance and abrasion resistance of PPS with nonstick properties of PTFE
-
Excellent Corrosion Protection – Enhanced barrier protection against rust and chemical attack; thick film prevents pinholes and corrosion pathways
-
Good Lubricity – PTFE content provides low friction and nonstick surface
-
Wide Temperature Range – Operates from -20°C to 230°C (-4°F to 446°F); virtually unaffected by solvents up to 205°C (400°F)
-
Excellent Chemical Resistance – Resists most acids, bases, and solvents
-
Good Abrasion Resistance – Durable PPS matrix provides protection against mechanical wear
-
Multiple Color Options – Available in various colors for identification and traceability

Processing Guidelines for Xylan 1391 Coating
| Step | Process |
|---|---|
| Surface Preparation | Alkaline cleaning or acetone degreasing + grit-blast (Sa2.5 grade, Ra 3–6 μm) |
| Primer Application (Recommended) | Apply Xylan® 2 primer for optimal adhesion and corrosion protection |
| Topcoat Application | Apply Xylan 1391 by spray (conventional or HVLP) to achieve high-build thickness |
| Dry Film Thickness | 20 – 30 μm (thicker than standard Xylan coatings) |
| Curing | Cure at 193°C (380°F) for 15–20 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. Ensure surfaces are clean, dry, and properly roughened to Sa2.5 grade, Ra 3–6 μm. Degrease thoroughly before grit-blasting.
High-Build Application: Xylan 1391 is formulated for thicker film application. Multiple coats may be required to achieve 20–30 μm dry film thickness. Ensure proper drying between coats.
Primer Application: Primer is recommended for optimal adhesion and maximum corrosion protection.
Curing: Cure at 193°C (380°F) for 15–20 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.
