857G-11190 Black – Low-Temperature PTFE Waterborne Primer for Industrial Applications

描述

857G-11190 Black is a waterborne 857G-11190 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-11190 Black PTFE Primer is specifically engineered as the foundational layer for PTFE topcoat systems, providing essential adhesion, corrosion protection, and enhanced durability. It acts as a robust “bridge” between the substrate and the topcoat, dramatically enhancing adhesion and preventing delamination, thus ensuring long-term durability of the nonstick coating system.

What distinguishes 857G-11190 is its enhanced wear resistance and anti-penetration properties. The black pigmented formulation offers improved abrasion resistance and barrier protection against media penetration, making it particularly suitable for demanding applications where mechanical wear and chemical exposure are concerns. Like other 857G series primers, it is a food-grade, aqueous-based dispersion that imparts nonstick properties to equipment used in food processing and other food contact applications. It delivers exceptional performance across an extraordinarily wide temperature range — from -270°C (-454°F) to 260°C (500°F) continuously.

With regular stock availability, we support both trial orders and large-volume bulk shipments for food processing equipment, industrial bakeware, chemical processing, and other demanding industrial environments.

Key Features of 857G-11190 Black PTFE Primer

• Enhanced Wear Resistance – Formulated for improved abrasion resistance, making it ideal for applications involving frequent mechanical contact and high friction scenarios.

• Anti-Penetration Properties – Provides effective barrier protection against media penetration, offering enhanced resistance to chemical and moisture ingress.

• Exceptional Low-Temperature Performance – Maintains physical integrity at temperatures as low as -270°C (-454°F) without cracking or hardening, making it suitable for cryogenic and aerospace applications.

• High-Temperature Stability – Continuous service up to 260°C (500°F) , the highest of any fluoroplastic, with intermittent tolerance up to 316°C (600°F).

• Superior Adhesion – Acts as a robust “bridge” between the substrate and the PTFE topcoat, providing foundational adhesion and preventing coating delamination.

• Food Grade Compliance – FDA approved for food contact applications, suitable for food processing equipment, bakeware, and other food-contact uses.

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

• Extremely Low Surface Energy – Coating surface energy is 18-20 dynes/cm; residual adhesion is significantly lower than uncoated surfaces.

• Low Coefficient of Friction – Friction coefficient stabilizes between 0.05 and 0.20, with static friction reduced by over 70% compared to bare metal.

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

• Outstanding Chemical Resistance – Resists concentrated acids (e.g., 98% sulfuric acid), strong alkalis (30% sodium hydroxide), and a wide range of organic solvents.

• Excellent Weatherability – Retains >80% gloss after 10+ years of outdoor exposure, with minimal chalking or degradation.

Typical Applications for 857G-11190 Black

Material Advantages

The 857G-11190 Black PTFE Primer is a waterborne PTFE primer that delivers:

• Enhanced Wear & Anti-Penetration – The black pigmented formulation provides superior abrasion resistance and barrier protection compared to standard primers, making it ideal for demanding applications.

• Exceptional Temperature Range – From -270°C (-454°F) to 260°C (500°F) continuously, with intermittent tolerance up to 316°C (600°F), offering unparalleled versatility for applications ranging from cryogenic to high-temperature environments.

• Enhanced Adhesion – Creates a protective layer over the substrate, decreasing porosity and preventing the topcoat from being absorbed, thus ensuring strong, lasting bonding.

• Food Safety – FDA compliant for food contact, enabling use in food processing and bakeware 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, 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, offering design flexibility.
