856G-300 Clear – FEP Waterborne Topcoat for Food Contact Systems

描述

856G-300 Clear is a waterborne 856G-300 Clear 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-300 Clear FEP Topcoat is a standard grade, 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-300 Clear 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 clear, transparent finish preserves the appearance of the underlying substrate while providing superior protection.

856G-300 is part of Chemours‘ product line transition, replacing 856G-200 (Clear) and 856G-204 (Green) in the waterborne FEP coatings portfolio. The 856G-300 series offers improved performance and consistency, making it the recommended choice for new applications.

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.

Processing Guidelines

Critical Processing Warnings:

• Primer Required: 856G-300 is a topcoat and must be used with a compatible primer system (e.g., 420G-71x, 470G-71x series). Do not apply directly to bare substrate.

• Surface Preparation: Proper surface preparation is critical for adhesion. Ensure surfaces are clean, dry, and properly roughened.

• Filtering: Always filter through 200 mesh stainless steel screen to prevent application defects.

• Curing: Cure time and temperature depend on primer selection and part mass. Always verify with test pieces.

• Storage: Store in original, sealed containers in a cool, dry place. Roll containers monthly for 15 minutes at 30 RPM.

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

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