857G-140 Black – PTFE Waterborne Filled Midcoat for Food Contact Systems

描述

857G-140 Black is a waterborne 857G-140 Black PTFE Filled Midcoat 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 857G-140 Black PTFE Filled Midcoat is specifically engineered as the intermediate layer in three-coat food contact systems. It is designed to be applied over primers such as 857G-030/857G-040 and under topcoats such as 857G-240, forming a complete FDA-compliant nonstick coating system. The aqueous-based dispersion is part of the Teflon industrial coatings portfolio, a uniquely blended multi-coat system of Teflon PTFE (polytetrafluoroethylene), FEP (fluorinated ethylene propylene copolymer), and PFA (perfluoroalkoxy) optimized to balance performance and durability.

The 857G-140 Black PTFE Filled Midcoat features a filled formulation that incorporates additional reinforcing materials, often in combination with ceramic fillers, to provide enhanced abrasion resistance and extended service life compared to unfilled midcoats. Its black pigmented finish provides a consistent industrial appearance while contributing to the overall thickness and performance of the coating system. 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 equipment, industrial bakeware, and other demanding applications requiring FDA-compliant nonstick coatings.

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.

• Batch-to-batch deviations may exist. For critical applications, validate performance with batch-specific COA certificate.

• 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:

• Surface Preparation: Proper cleaning and roughening are critical for adhesion. Unless explicitly noted, most Teflon industrial coatings require primer application.

• System Integrity: 857G-140 is the midcoat layer and must be used with compatible primer (857G-030/857G-040) and topcoat (857G-240) systems.

• Film Build Control: Maintain film build per coat at 15.2 – 20.3 µm (0.600 – 0.800 mil).

• Wet-on-Wet Application: Midcoat and topcoat can be applied wet-on-wet without intermediate drying.

• Curing: Requires only one full bake cycle. Cure time depends on part mass and oven characteristics. Peak temperature should be carefully controlled.

• Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.

• Shelf Life: 18 months in unopened, clean, dry storage.
