857G-083 Dark Purple – PTFE Waterborne Primer for Food Contact Systems

描述

857G-083 Dark Purple is a waterborne 857G-083 Dark Purple 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-083 Dark Purple PTFE Primer is a waterborne primer specifically engineered as the foundational layer for PTFE topcoat systems in two-coat (primer/topcoat) or three-coat (primer/midcoat/topcoat) configurations. Its core function is to serve as a robust “bridge” between the substrate and the PTFE topcoat, dramatically enhancing adhesion and ensuring long-term durability of the nonstick coating system.

The 857G-083 Dark Purple PTFE Primer is an aqueous-based dispersion that imparts nonstick properties to equipment used in food processing and other food contact applications. Approved for food contact, this primer delivers the highest operating temperature of any fluoroplastic (260°C / 500°F), an extremely low coefficient of friction, good abrasion resistance, and good chemical resistance. A distinctive feature of 857G-083 is its ability to be air dried or force dried at 105°C, offering flexibility in processing and reduced energy consumption.

With regular stock availability, we support both trial orders and large‑volume bulk shipments for food processing equipment, industrial bakeware, and other demanding applications requiring FDA-compliant nonstick coatings.

• Distinctive Dark Purple Color – Provides a unique dark purple appearance that aids in visual inspection and coverage verification during application.

• High Temperature Resistance – Continuous service temperature up to 260°C (500°F), the highest of any fluoroplastic.

• Low Coefficient of Friction – Extremely low friction coefficient, contributing to superior nonstick performance.

• Good Abrasion Resistance – Provides good abrasion resistance, extending the service life of the coating system.

• Good Chemical Resistance – Offers good chemical resistance, protecting substrates from corrosion and chemical attack.

• Optimized Film Build – Recommended DFT of 7 – 10 µm ensures proper adhesion without excessive build.

Typical Applications for 857G-083 Dark Purple

Material Advantages

The 857G-083 Dark Purple PTFE Primer is a waterborne PTFE primer that delivers:

• 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 approved for food contact, enabling use in food processing and food contact applications.

• Processing Flexibility – Air dry capability offers significant advantages in processing flexibility and reduced energy consumption compared to primers requiring high-temperature curing.

• 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.

• Distinctive Appearance – Dark purple color provides clear visual differentiation and aids in quality control during application.

Chemours, as the inventor of Teflon, brings over 80 years of fluoro-polymer expertise, ensuring batch-to-batch consistency, reliable supply, and full technical support.

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: The primer serves as the critical foundation for the entire coating system. Proper application and drying are essential for optimal adhesion and durability.

• Topcoat Compatibility: 857G-083 is compatible with PTFE topcoat systems in two-coat or three-coat configurations. Ensure topcoat selection matches your specific application requirements.

• Drying Flexibility: 857G-083 can be air dried or force dried at 105°C, offering significant processing flexibility.

• Film Build Control: Maintain recommended DFT at 7 – 10 µm. Excessive film build may affect adhesion and performance.

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

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