描述
420G-715 Brown is a solvent-based 420G-715 Brown 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. For more product options and company information, please visit our website at https://szrqchem.com/.
420G-715 Brown is a solvent-based primer formulated with special blends of fluoroplastics and other high-performance resins and additives to provide excellent adhesion on metallic substrates and protection against corrosion. This primer is designed to work on any metallic substrate that can withstand the recommended curing temperature. Its core function is to serve as a robust “bridge” between the substrate and the topcoat, dramatically enhancing adhesion and fundamentally resolving coating delamination issues to ensure long-term durability of the coating system.
Primers effectively prepare surfaces before coating application by creating a protective layer over the substrate that decreases the porosity of the coating so that it is not absorbed by the substrate. The 420G-715 primer is FDA compliant for food contact applications per 21CFR, making it suitable for food processing equipment, industrial bakeware, and other food‑contact uses. The solvent-based formulation provides excellent wetting, leveling, and adhesion properties for demanding industrial applications. The brown pigmented finish (closest RAL 8001) provides consistent industrial appearance while ensuring proper coverage verification.
Important Note: 420G-715 is a solvent-based primer formulated with nMP (N-Methyl-2-pyrrolidone). For applications requiring an nMP-free solution, 470G-715 is the equivalent alternative.
With regular stock availability, we support both trial orders and large‑volume bulk shipments for chemical processing, food equipment, industrial bakeware, automotive components, and other demanding industrial applications.

Processing Guidelines
| Step | Process |
|---|---|
| Substrate | Carbon steel, stainless steel, aluminum |
| Surface Preparation | Degrease then abrasive blasting to achieve proper surface profile for adhesion. Recommended roughness: 0.2‑0.3 mil (4‑8 µm). For carbon steel, best results are achieved with grit blasting, and spraying should be done as soon as possible after blasting |
| Coating Preparation | Bring to room temperature. Mix thoroughly until homogeneous and filter through 100 mesh (approx. 146 µm) stainless steel screen |
| Thinning | If needed, dilute with T-8718 (N-Methyl-2-pyrrolidone) at 1‑2% by volume |
| Primer Application | Apply via conventional or HVLP spray |
| Recommended DFT | 10 – 12 µm (0.4 – 0.5 mil) |
| Drying | Force dry at 160°C – 220°C |
| Topcoat Application | Apply compatible FEP or PFA topcoat over dried primer. Suitable for topcoats in powder or liquid form |
| Curing | Follow topcoat manufacturer’s recommended schedule. Sintering temperature depends on the topcoat being used |
| Storage | Store at normal room temperature. Protect from heat, sparks, and open flame |
Critical Processing Warnings:
-
Primer as Foundation: 420G-715 serves as the foundational layer for FEP/PFA topcoat systems. For some surfaces, it’s recommended to use a primer before applying Teflon FEP coatings.
