857G-505 Black – Low-Temperature PTFE Waterborne Primer for Industrial Applications

描述

857G-505 Black is a waterborne 857G-505 Black PTFE 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/.

This 857G-505 Black PTFE Primer is a waterborne primer specifically engineered as the foundational layer for PTFE topcoat systems. Its core function is to serve as a robust “bridge” between the substrate and the topcoat, dramatically enhancing adhesion and ensuring long-term durability of the nonstick coating system. The primer is part of the PTFE two-coat (primer/topcoat) system, which delivers the highest operating temperature of any fluoroplastic at 260°C (500°F) , an extremely low coefficient of friction, good abrasion resistance, and excellent chemical resistance.

What sets 857G-505 apart is its exceptional low-temperature performance. The coating can maintain physical integrity at temperatures as low as -270°C (-454°F) without cracking or hardening, making it an ideal choice for cryogenic equipment, liquid-oxygen transfer lines, and aerospace components that operate in extreme cold environments. The waterborne formulation offers low VOC emissions, environmentally friendly processing, and safer handling for operators.

With regular stock availability, we support both trial orders and large‑volume bulk shipments for cryogenic equipment, aerospace components, oil & gas applications, food processing equipment, and other demanding industrial applications.

Key Features of 857G-505 Black PTFE Primer

• Exceptional Low-Temperature Performance – Maintains physical integrity at temperatures as low as -270°C (-454°F) without cracking or hardening. Ideal for cryogenic equipment, liquid-oxygen transfer lines, and aerospace components.

• Superior Adhesion – Acts as a robust “bridge” between the substrate and the PTFE topcoat, preventing coating delamination and ensuring the entire coating system remains firmly bonded.

• Food Grade Compliant – FDA compliant for food contact applications per 21CFR. Suitable for food processing equipment, industrial bakeware, and other food contact applications.

• Waterborne Formulation – Low VOC emissions, environmentally friendly processing, and safer for operators.

• Excellent Corrosion Protection – Provides effective corrosion resistance, protecting substrates from chemical attack and environmental degradation.

• Wide Topcoat Compatibility – Suitable for use with PTFE topcoat systems in two-coat or multi-coat configurations.

• Optimized Film Build – Designed for optimal primer thickness to ensure proper adhesion without excessive build.

• Broad Substrate Compatibility – Can be applied to carbon steel, aluminum, stainless steel, alloy steel, brass, magnesium, as well as non-metallic materials including glass, fiberglass, and certain rubbers and plastics.

Typical Applications for 857G-505 Black

Material Advantages

The 857G-505 Black PTFE Primer is a waterborne PTFE primer that delivers:

• Exceptional Temperature Range – From -270°C (-454°F) to 260°C (500°F) , offering unparalleled versatility for applications ranging from cryogenic to high-temperature environments.

• Enhanced Adhesion – Primers effectively prepare surfaces before coating application, creating a protective layer over the substrate that decreases porosity and prevents the coating from being absorbed by the substrate.

• Food Safety – FDA compliant for food contact, enabling use in food processing and food contact applications.

• Chemical Inertness – PTFE-based formulation provides excellent resistance to chemicals and corrosion.

• Thermal Stability – Maintains performance at continuous service temperatures up to 260°C (500°F), the highest of any fluoroplastic.

• Environmental Compliance – Waterborne carrier reduces VOC emissions compared to solvent-based alternatives.

• Broad Substrate Compatibility – Applicable to a wide range of metals and non-metals including carbon steel, aluminum, stainless steel, alloy steel, brass, magnesium, glass, fiberglass, and certain rubbers and plastics.

Typical Properties

Important Notes on Typical Data:

• Values listed are typical and sourced from Chemours official data sheets. They do not constitute binding product specification.

• Batch‑to‑batch deviations may exist. For critical applications, validate performance with batch‑specific COA certificate.

• Final performance depends on substrate preparation, application method, and curing conditions.

• Chemours original TDS shall serve as definitive technical reference. Request the latest official TDS from our sales team.

Processing Guidelines

Critical Processing Warnings:

• Surface Preparation: Proper surface preparation is critical for adhesion. Ensure surfaces are clean, dry, and properly roughened.

• Primer as Foundation: Unless explicitly noted otherwise, most Teflon industrial coatings require primer application. The primer serves as the critical foundation for the entire coating system.

• Topcoat Compatibility: 857G-505 is compatible with PTFE topcoat systems in two-coat or multi-coat configurations.

• Temperature Considerations: The primer provides exceptional performance from -270°C to 260°C. Ensure your application requirements fall within this range.

• Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight.

• Shelf Life: 18 months in unopened, clean, dry storage.
