857G-030 Black – PTFE Waterborne Filled Primer for Food Contact Systems

描述

857G-030 Black is a waterborne 857G-030 Black PTFE Filled 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-030 Black PTFE Filled Primer is specifically engineered as the foundational layer for PTFE / PFA / FEP topcoat systems. 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.

The 857G-030 Black PTFE Filled Primer is an aqueous-based dispersion that imparts nonstick properties to equipment used in food processing, office automation, paper, textile, and commercial laundry applications. When used in combination with PTFE / PFA / FEP topcoats, the resulting composite coating system delivers excellent nonstick release, easy cleanability, low coefficient of friction, and significantly enhanced wear resistance. The filled formulation provides additional reinforcement, improving abrasion resistance and extending service life.

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

Key Features of 857G-030 Black PTFE Filled Primer

• FDA Food Contact Compliant – Approved for food contact applications per 21CFR, suitable for food processing equipment, industrial bakeware, and other food contact applications.

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

• Filled Formulation – Incorporates additional reinforcing materials to enhance abrasion resistance and extend service life compared to unfilled primers.

• Enhanced Durability – By improving adhesion, the primer significantly extends the overall service life of the coating system, making it more resistant to wear, impact, and thermal cycling.

• Improved Corrosion Resistance – Provides additional rust and chemical corrosion protection, forming a more comprehensive protective system when combined with the topcoat, particularly suitable for harsh environments.

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

• Broad Topcoat Compatibility – Suitable for use with PTFE, PFA, and FEP topcoat systems.

• Optimized Film Build – Single coat film build of 0.300 – 0.400 mil (7.62 – 10.2 microns) ensures proper adhesion without excessive build.

• Thermal Stability – Continuous service temperature up to 260°C (500°F); cure temperature at 435°C (815°F).

• Optimized Surface – A smooth, well-adhered primer layer allows the subsequent PTFE topcoat to distribute more evenly, resulting in better smoothness, nonstick properties, and aesthetic appearance.

Typical Applications for 857G-030 Black

Material Advantages

The 857G-030 Black PTFE Filled Primer is a waterborne, filled PTFE primer that delivers:

• Enhanced Adhesion – Primers effectively prepare surfaces before coating application, giving the coating a smooth surface with which it can bind by creating a protective layer over the substrate. This protective bind decreases the porosity of the coating so that it is not absorbed by the substrate.

• Filled Formulation Benefits – The filled primer incorporates additional reinforcing materials that enhance abrasion resistance and extend service life compared to unfilled primers.

• 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.

• Food Safety – FDA compliant for food contact per 21CFR, enabling use in food processing and food contact applications.

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.

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

• Topcoat Compatibility: 857G-030 is compatible with PTFE, PFA, and FEP topcoat systems. Ensure topcoat selection matches your specific application requirements.

• Film Build Control: Maintain single coat film build at 7.62 – 10.2 µm (0.300 – 0.400 mil). Excessive film build may affect adhesion and performance.

• Curing: Cure time depends on part mass and oven characteristics. Always verify with test pieces.

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

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