描述
Xylan 1661 is a waterborne, PTFE-based industrial anti-corrosion topcoat 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 (high PTFE lubricity for fasteners), Xylan 1052 (extreme pressure with MoS₂), or Xylan 1070 (solvent-based fastener coating), Xylan 1661 is primarily formulated as a waterborne anti-corrosion topcoat for metal components exposed to moderate to severe environments . It serves as a fluoropolymer coating for electrocoat masking and complies with GM 6076M standard for automotive applications .
Xylan 1661 is an environmentally friendly waterborne/VOC-compliant formulation that offers low VOC emissions and meets ISO 14001 and RoHS environmental standards . It is typically applied over a Xylan® 1 or Xylan® 2 primer, forming a dual-layer protection system that significantly enhances adhesion and overall durability .
The coating provides excellent corrosion resistance with 1500–4000 hours salt spray protection when properly primed . It features excellent adhesion to properly prepared steel and aluminum substrates (ASTM D3359 4B–5B) , and operates reliably from -250°C to 285°C .

Processing Guidelines for Xylan 1661 Coating
| Step | Process |
|---|---|
| Surface Preparation | Degrease (acetone or isopropanol) → grit-blast (Sa2.5, Ra 1.5–4.0 μm) → optional zinc/manganese phosphate for steel |
| Primer Application (Recommended) | Apply Xylan® 1 or Xylan® 2 primer for enhanced adhesion and corrosion protection |
| Coating Preparation | Low-speed mechanical stirring; dilute with deionized water only |
| Application | Conventional spray (HVLP) or dip coating |
| Curing | Bake at 370–390°C 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 and corrosion performance. Degrease thoroughly and grit-blast to Sa2.5 grade with Ra 1.5–4.0 μm .
Primer Application: Xylan 1661 is typically applied over Xylan® 1 or Xylan® 2 primer for maximum corrosion protection and adhesion .
Coating Mixing: Use only deionized water for dilution. Never use tap water, as minerals and impurities can destabilize the coating .
Curing: Cure temperature is substrate temperature, not oven temperature. 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.
