描述
857G-240 Clear is a waterborne 857G-240 Clear PTFE 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 857G-240 Clear PTFE Topcoat is a high-performance waterborne topcoat specifically engineered as the final layer for three-coat food contact systems. It is designed to be applied over primers such as 857G-030/857G-040 and midcoats such as 857G-130/857G-135 or 857G-140, forming a complete FDA-compliant nonstick coating system. The aqueous-based dispersion imparts nonstick properties on equipment used in food processing, office automation, paper, textile, and commercial laundry applications.
The 857G-240 Clear PTFE Topcoat delivers outstanding non-stick release properties, an extremely low coefficient of friction, and excellent thermal stability at continuous service temperatures up to 260°C (500°F). Its clear finish provides a smooth, transparent protective layer that preserves the appearance of the underlying substrate while offering superior abrasion resistance and extended service life. 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, office automation components, 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 |
| Primer Application | Apply 857G-030 or 857G-040 primer via spray |
| Primer Cure | Follow Chemours recommended cure schedule for primer |
| Midcoat Application | Apply 857G-130/857G-135 or 857G-140 midcoat via spray |
| Topcoat Application | Apply 857G-240 Clear topcoat via conventional or HVLP spray – wet-on-wet over midcoat |
| 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 |
| Curing | Total system: Minimum 5 min at 428°C (802°F) or 3 min at 435°C (815°F) metal temperature. Peak temperature should not exceed 440°C (824°F) |
