858G-210 Clear – PFA Waterborne Topcoat for Thin Film Industrial Applications

858G-210 Clear is a waterborne 858G-210 Clear PFA Topcoat from Chemours‘ Teflon industrial coatings portfolio, genuinely manufactured by Chemours and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Chemours technical documentation. For more product options and company information, please visit our website at https://szrqchem.com/.

This 858G-210 Clear PFA Topcoat is a waterborne PFA (perfluoroalkoxy) topcoat engineered as the final layer for multi‑coat systems. PFA is a melt‑processable fluoropolymer that melts and flows during baking to form nonporous, smooth, and highly durable films. These multi‑coat systems provide higher continuous use temperatures (260°C / 500°F), have a high dielectric strength, and are considered tougher than PTFE or FEP.

What distinguishes 858G-210 is its thin film capability and suitability for complex geometries. It is specifically designed for parts that may not be easily powder coated, such as parts with acute angles or parts requiring a thinner coating than a powder coat can provide. The coating has a variety of application uses such as general industrial, food processing and office automation. The clear, transparent finish preserves the appearance of the underlying substrate while providing exceptional nonstick release, chemical resistance, and thermal stability up to 260°C (500°F).

The 858G-210 Clear PFA Topcoat is FDA compliant for food contact applications per 21CFR, making it suitable for food processing equipment, industrial bakeware, and other food‑contact uses. As a waterborne coating, it offers low VOC emissions, making it an environmentally responsible choice for modern industrial facilities.

With regular stock availability, we support both trial orders and large‑volume bulk shipments for aerospace, automotive, chemical processing, food processing, and other demanding industrial applications.

Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from Chemours official data sheets. They do not constitute binding product specification.

• Physical constants are averages only and may vary up to ±5% of the values shown.

• Final performance depends on substrate preparation, application method, and curing conditions.

• Chemours original TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.

Processing Guidelines

Critical Processing Warnings:

• Primer Required: 858G-210 is a topcoat and must be used with a compatible primer system (e.g., 420G-70X series or 850G-314).

• Surface Preparation: Proper surface preparation is critical for adhesion. Any residual oil on the surface will affect the color of the cured film and will adversely affect adhesion.

• Mixing: Insufficient mixing can result in application defects. Mix for 15 minutes or more until homogeneous.

• Filtering: Always filter through 100 mesh (105μm) stainless steel or nylon to prevent application defects.

• Thin Film Application: Single coat DFT is 0.8-1.2 mil (20-30 μm). Total film builds up to 3 mil (75 μm) are possible with multiple coats.

• Curing: First coat: 400°C for 5-7 minutes. Subsequent coats: 370°C for 15 minutes.

• Freeze Protection: Waterborne products must be protected from freezing.

• Shelf Life: 18-24 months in unopened, clean, dry storage at 18-24°C.
