描述
850G-314 Green is a PTFE (polytetrafluoroethylene) waterborne acid primer 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.
This green primer is part of the 850G-3XX series of acid primers and is designed to be used as the foundation for PTFE, PFA, and FEP topcoat systems. Unlike other primers, 850G-3XX primers do not contain any polymer other than PTFE. Adhesion to the substrate results from a chemical reaction of the acid accelerator with the metal.
850G-314 Green must be activated with 850-7799 Acid Accelerator before use. The activated product (851-204) has a short pot life at room temperature. This primer provides exceptional tolerance to less thorough surface preparation and over-curing, as well as superior corrosion protection compared to conventional primers. The green color makes it ideal for color-matched systems where visual identification and process control are important.
850G-314 Green is not intended for direct food contact. It can also be used as a one-coat system without a topcoat in certain applications.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for industrial, automotive, aerospace, chemical processing, and heavy-duty non-stick applications.

Material Advantages of 850G-314 Green
What makes 850G-314 Green the preferred choice for PTFE coating primer applications? Below are its core practical advantages:
Unique Acid Primer Chemistry for Superior Adhesion
Unlike other primers, 850G-314 series acid primers contain no polymer other than PTFE. Adhesion is achieved through a chemical reaction of the acid accelerator with the metal substrate. This results in an exceptionally strong bond that outperforms conventional primers.
Exceptional Process Tolerance
850G-314 Green demonstrates exceptional tolerance to less thorough substrate preparation (cleaning and grit blasting) and over-curing (excessive temperature and/or time). This makes it more forgiving in production environments where process control may vary.
Superior Corrosion Protection
Acid primers have shown better corrosion protection of metallic substrates compared to conventional primers, making them ideal for applications in aggressive chemical environments.
Color-Matched Green Finish
The green color provides easy visual identification of coated parts, aids in process quality control, and is ideal for color-matched systems where the primer color complements the overall coating appearance.
High Temperature Stability
With maximum service temperature of 260°C (500°F), this primer maintains its adhesion and protective properties in high-temperature environments where conventional primers would fail.
Versatile Compatibility
850G-314 Green can be used as a primer for PTFE, PFA, and FEP topcoats. In some applications, it can even be used as a one-coat system without a topcoat.
Waterborne, Low VOC
The waterborne formulation provides a more environmentally friendly alternative to solvent-based systems, with low VOC emissions and easier handling.

Important Notes on Typical Data:
Values listed are typical and sourced from Chemours official data sheets. They do not constitute binding product specification.
Physical constants are averages and may vary up to ±5% of the values shown.
Viscosity values are typical of release viscosity; these products typically increase to ~500 cP after 1 week. The viscosity will decrease to normal application limits with the addition of 850-7799 acid accelerator.
Final performance depends on substrate preparation, application method, and curing conditions.
