描述
857G-135 Black is a waterborne 857G-135 Black PTFE 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-135 Black PTFE 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) to optimize performance.
The 857G-135 Black PTFE Midcoat provides enhanced film build and durability compared to two-coat systems, offering superior abrasion resistance and extended service life. 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.

Processing Guidelines
| Step | Process |
|---|---|
| Substrate | Rolled and cast aluminum, stainless steel |
| Surface Preparation | Degrease then abrasive blasting to achieve proper surface profile |
| Coating Preparation | Gently mix 15 minutes or more until homogeneous. Set mixer speed to create a vortex while avoiding air entrapment. Use axial flow impeller |
| Filtering | 60 mesh (approx. 250 μm) stainless steel or nylon |
| Primer Application | Apply compatible primer (857G-030 or 857G-040) via spray |
| Primer Cure | Follow Chemours recommended cure schedule for primer |
| Midcoat Application | Apply 857G-135 Black via conventional or HVLP spray. Air pressure: 3-5 kg/cm²; fluid delivery pressure: 0.8-1.2 kg/cm² |
| Topcoat Application | Apply 857G-240 Clear topcoat – wet-on-wet over midcoat |
| Curing | Total system: Follow Chemours recommended cure schedule at 435°C (815°F) |
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-135 is the midcoat layer and must be used with compatible primer and topcoat 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: 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.
