描述
856G-303 Black is a waterborne 856G-303 Black FEP 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 856G-303 Black FEP Topcoat is a food-grade, waterborne FEP (fluorinated ethylene propylene) topcoat engineered as the final layer for multi‑coat FEP systems. FEP is a melt‑processable fluoropolymer that melts and flows during baking to form nonporous, smooth, and highly durable films. Its unique ability to melt and flow ensures a pinhole‑free, continuous coating that provides exceptional barrier protection.
The 856G-303 Black FEP Topcoat is FDA compliant for food contact applications per 21CFR, making it suitable for food processing equipment, industrial bakeware, and other food‑contact uses. It delivers outstanding nonstick release properties, excellent chemical resistance, and low friction characteristics. The black pigmented finish provides a consistent industrial appearance (closest RAL 9004) while offering superior protection.
856G-303 is part of Chemours’ product line transition from 856G-2xx to 856G-3xx series. The 856G-3xx series offers improved performance and consistency, with a shelf life of 12 months—double that of the previous 856G-2xx series. The waterborne formulation 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 food processing, mold release, chemical processing, and other demanding industrial applications.

| Filtering | 200 mesh (approx. 74 μm) stainless steel or equivalent |
| Primer Application | 856G-303 must be used with compatible primer system. Unless explicitly noted, most Teflon industrial coatings require primer application |
| Topcoat Application | Apply 856G-303 Black topcoat via conventional or HVLP spray |
| Recommended DFT | Max 12 µm (approx. 0.5 mil) per coat |
| Curing | Bake at 380°C (716°F) . Long bake recommended. Cure time depends on part mass and oven characteristics |
| Storage | Store in original, sealed containers in a cool, dry place. Protect from freezing |
| Shelf Life | 12 months in unopened, clean, dry storage |
