描述
857G-11170 Yellow is a waterborne 857G-11170 Yellow 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-11170 Yellow PTFE Primer is specifically engineered as the foundational layer for PTFE topcoat systems, providing essential adhesion and corrosion protection. 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-11170 is its enhanced weatherability. The yellow pigmented formulation offers improved resistance to UV degradation and outdoor exposure, making it particularly suitable for applications requiring long-term color stability and weatherability. 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, outdoor applications, and other demanding industrial environments.
Key Features of 857G-11170 Yellow PTFE Primer
