We are a professional manufacturer specializing in fluoropolymer materials and tubing products.
The PTFE water-based double-layer coating offers excellent non-stick performance, high temperature resistance, and superior corrosion protection. It is widely used in molds, conveyors, and food machinery requiring clean release and long-lasting durability.
PTFE Water-Based Coating (Double Layer) is a dual-layer fluoropolymer system composed of a primer and a topcoat, both based on PTFE dispersions. This coating is engineered for applications requiring enhanced non-stick properties, high temperature endurance, and superior chemical resistance.
As a water-based solution, it offers an eco-friendly and low-VOC alternative to solvent-based coatings, while maintaining the excellent durability and performance of PTFE. The dual-layer structure ensures strong adhesion, extended service life, and reliable performance even under continuous high-temperature operations.

Q1: What is the difference between PTFE water-based coatings and solvent-based coatings?
A1: PTFE water-based coatings are formulated with water as the dispersion medium, making them more eco-friendly and low-VOC compared to solvent-based versions. They provide the same non-stick and corrosion-resistant properties while reducing environmental impact.
Q2: Can this coating withstand continuous high temperatures?
A2: Yes. The PTFE double-layer coating is designed for excellent thermal stability and can perform reliably in continuous service up to 260°C (500°F), with sintering temperatures up to 420°C during curing.
Q3: What substrates can PTFE coatings be applied to?
A3: PTFE coatings are typically applied to metals (steel, stainless steel, aluminum) and can also be used on certain engineered plastics after proper surface preparation and priming.
Q4: Is the coating food-safe?
A4: Yes. PTFE coatings are widely used in food processing machinery and cookware. When properly cured, they are compliant with FDA standards for food contact applications.
Q5: What is the recommended coating thickness?
A5: The typical thickness for PTFE water-based double-layer coatings is 25–35 μm, which provides optimal balance between durability, adhesion, and non-stick performance.
Q6: Can you provide custom colors or finishes?
A6: Yes. Standard colors include black, grey, and blue, but customized colors can be developed upon request. Finishes are usually matte or semi-gloss.
Q7: What industries benefit most from PTFE coatings?
A7: Industries such as food processing, automotive, mold manufacturing, conveyor systems, and chemical processing benefit most, due to the coating’s non-stick, corrosion resistance, and wear resistance properties.
