Features Of KEY-212 Lotus Rhyme Fluorine-Free High-Temperature Nano Coating

  1. Fluorine-free formulation ensures compliance with global PFAS restrictions and eliminates long-term environmental persistence concerns.

  2. Thermally stable up to 650°C in inert atmosphere, retaining nano-structured integrity and surface functionality under cyclic high-temperature exposure.

  3. Superhydrophobic and oleophobic surface behavior (contact angle >150° for water, >140° for hexadecane) achieved without fluorinated surfactants.

  4. Nano-dispersed ceramic-silica hybrid matrix enables exceptional adhesion to metals, ceramics, and high-performance alloys after standard curing.

  5. Low-VOC, solvent-based system compatible with conventional industrial spray, dip, and brush application methods.

Typical Applications Of KEY-212 Lotus Rhyme Fluorine-Free High-Temperature Nano Coating

  1. Aerospace engine components requiring thermal barrier and anti-fouling protection above 500°C.

  2. Industrial furnace linings and heat-treatment fixtures exposed to oxidizing and reducing atmospheres.

  3. Exhaust manifolds, turbocharger housings, and catalytic pre-heater substrates in emission-critical powertrain systems.

  4. High-temperature sensors and thermocouple sheaths requiring dielectric stability and corrosion resistance at elevated service temperatures.

  5. Ceramic fiber insulation coatings for fire-rated enclosures and nuclear instrumentation housings.

KEY-212 Lotus Rhyme Fluorine-Free High-Temperature Nano Coating – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for KEY-212?

A: KEY-212 is a proprietary multi-component nanocomposite; it does not carry a single CAS number. Individual raw materials are fully disclosed in the Safety Data Sheet (SDS) Section 3, and batch-specific composition reports are available under NDA.


Q2: What is the recommended dry film thickness (DFT) and typical consumption rate per square meter?

A: Optimal performance is achieved at 12–18 μm DFT (single coat). Consumption averages 8–10 g/m² for spray application on smooth metal surfaces; porous or rough substrates may require 12–15 g/m².


Q3: How does KEY-212 differ from fluorinated high-temperature coatings such as KEY-209 or commercial PTFE-based systems?

A: Unlike fluorinated alternatives, KEY-212 eliminates bioaccumulative PFAS chemistry while matching thermal stability up to 550°C in air. It offers superior oxidation resistance and avoids volatile fluoropolymer decomposition byproducts above 350°C.


Q4: Are there any known migration or extractable compound concerns under high-temperature food-contact or pharmaceutical processing conditions?

A: KEY-212 contains no volatile organic solvents post-cure and exhibits negligible leachables (<0.1 ppm total organics) under simulated extraction per USP <87> and ISO 10993-12 protocols at 250°C. Not approved for direct food contact; intended for equipment-facing surfaces only.
