描述
858G-917 Ruby Red is a waterborne 858G-917 Ruby Red PFA High Build 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 858G-917 Ruby Red PFA Topcoat is a filled, high build waterborne PFA (perfluoroalkoxy) topcoat engineered as the final layer for multi‑coat systems. PFA is a melt‑processable fluoropolymer that melts and flows during baking to form nonporous, smooth, and highly durable films. These multi‑coat systems provide higher continuous use temperatures (260°C / 500°F), have a high dielectric strength, and are considered tougher than PTFE or FEP.
What distinguishes 858G-917 is its filled formulation and exceptional high build capability. This coating is specifically formulated to reduce permeation and should be considered whenever permeation poses a risk to fluoropolymer coating performance. The proprietary filler materials in the Ruby Red protective coating dramatically slow the permeation process. The coating can be applied in multiple layers at 3 – 10 mils per coat, with a maximum total film build up to 40 mils (approx. 1,000 µm). The ruby red pigmented finish provides a distinctive industrial appearance while offering superior protection against extremely corrosive chemicals.
The 858G-917 Ruby Red PFA Topcoat is a waterborne coating offering 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 chemical processing, pumps, tanks, valves, aerospace, automotive, semiconductor, and other demanding industrial applications.

| Coating Preparation | Roll mix 30 minutes or more at 30 RPM. Monthly rolling (30 RPM, 15 minutes) helps stability and reduces sedimentation |
| Filtering | 60-80 mesh stainless steel or nylon screen |
| Primer Application | Recommended primer: 420G-70X series, preferably 420G-71X series. DFT: 10-15 µm. Bake at 220°C for 15 minutes (metal temperature) |
| First Coat Application | Apply 858G-917 via conventional or reduced pressure spray gun. Nozzle: 1.2-1.8 mm. Atomization pressure: 1.5-3 kg. Spray distance: 20-30 cm from substrate |
| First Coat DFT | 80-100 µm (3.1-3.9 mil) |
| First Coat Drying | 20-30 minutes at 120-150°C (metal temperature). Oven max: 150°C |
| First Coat Curing | Ramp oven from 150°C to 380°C, metal升温 time should be 20 minutes. Bake at 370-380°C, keep temperature difference between metal and oven small to prevent bubbling |
| Subsequent Coats | Each subsequent coat up to 250 µm (9.8 mil) DFT |
| Multi-Layer Curing | Ramp oven from 150°C to max 340°C, metal升温 time 20 minutes |

| Minimum Layers | Minimum 2 layers recommended to reduce pinhole risk |
| Recommended Total DFT | 1,500 – 2,000 µm (60 – 80 mil) |
| Clear Overcoat (Optional) | After final 858G-917 coat, apply 857G-110, 40-70 µm wet-on-wet; or apply powder 532G-5010 with long bake |
| Repair | Thick coatings: sand with P80-120 sandpaper. Thin coatings: P400. Avoid damaging primer |
| Spark Test | Properly sintered 500 µm coating passes 4-5 kV pinhole test |
| Complex Parts | Dilute with distilled water if needed for complex shapes |

Critical Processing Warnings:
-
Primer Required: 858G-917 is a topcoat and must be used with a compatible primer system (e.g., 420G-70X series). Unless explicitly noted, most Teflon industrial coatings require primer application.
-
Minimum Layers: Apply minimum 2 layers to reduce pinhole risk.
-
Temperature Control: Keep the difference between metal and oven temperature small to prevent bubbling. Bake temperature of the first coat is critical for adhesion to the primer.
-
Surface Preparation: Proper surface preparation is critical for adhesion. Grit blast with aluminum oxide.
-
Mixing: Insufficient mixing can result in application defects. Roll mix 30 minutes or more at 30 RPM.
-
Filtering: Always filter through 60-80 mesh screen to prevent application defects.
-
Film Build Control: Total film build should not exceed recommended limits. First coat limited to 80-100 µm; subsequent coats up to 250 µm per coat.
-
Freeze Protection: Waterborne products must be protected from freezing.
-
Shelf Life: 18-24 months in unopened, clean, dry storage at 18-25°C.
