This 857G-040 Black PTFE Filled Primer is specifically engineered as the foundational layer for PTFE / PFA / FEP topcoat systems. It is an aqueous-based dispersion that imparts nonstick properties on equipment used in food processing, office automation, paper, textile, and commercial laundry applications. The primer utilizes On-Smooth technology, allowing application on smooth aluminum substrates without the need for grit blasting, significantly simplifying the surface preparation process.

The 857G-040 Black PTFE Filled Primer is part of the Specialty 3 Coat Reinforced Teflon Coating System, a premium multi-coat system that is a unique blend of PTFE, PFA, and FEP combined with ceramic fillers. For additional durability, ceramic fillers have been added to the primer layer. The resulting coating system delivers superior abrasion resistance, excellent nonstick properties, thermal stability to 500°F, and extended 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.

Processing Guidelines

Critical Processing Warnings:

• Surface Preparation: Proper surface preparation is critical for adhesion. Elements of impurity can have a reverse impact on quality of the coated article.

• On-Smooth Advantage: 857G-040 utilizes On-Smooth technology, allowing application on smooth aluminum substrates without grit blasting, significantly reducing processing steps and costs.

• 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-040 is compatible with PTFE, PFA, and FEP topcoat systems. Ensure topcoat selection matches your specific application requirements.

• Wet-on-Wet Application: The primer is force dried, and the midcoat and topcoat are applied wet-on-wet and cured in a single bake cycle.

• 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: Requires only one full bake cycle at 800°F. Cure time depends on part mass and oven characteristics.

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

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