NADREIN Coating
NADREIN is a reinforced anti-corrosion material developed by PodLee Company in the United States. This product utilizes nano-scale silica sol and specialized corrosion-resistant components to form an interpenetrating network, providing exceptional resistance to various inorganic and organic acids, as well as solvents.
The unique molecular structure of NADREIN ensures high adhesion and fracture strength even under high-temperature conditions (302℉ / 150°C) and severe thermal cycling loads, effectively preventing delamination and cracking of the paint film. Its molecular-level density blocks chemical media from penetrating the metal surface via capillary action, thereby eliminating corrosion.
PodLee's advanced design capabilities and manufacturing processes ensure NADREIN's superior corrosion resistance, excellent thermal shock resistance, and high tolerance to thermal cycling loads. Easy application via spraying and proven reliability in real-world applications worldwide make NADREIN a trusted choice.

Advantages
Superior Corrosion Resistance – Ideal for harsh environments such as marine and chemical industries.
Thermal Cycling Load Tolerance – Enhances safety and reliability of protective coatings.

Surface Preparation
Proper surface preparation is critical for optimal performance:
Degrease and desalinate surfaces. Rinse salt residues with freshwater in marine environments.
Clean surfaces and remove rust via mechanical sandblasting or power tools (rust removal grade: SA2.5 or ST3).
Wipe surfaces clean with a dry cloth to remove moisture and loose rust.
Mixing
Ensure ambient temperature is 50 – 104℉ (10 – 40°C). When the ambient temperature is below 41℉ (5°C),
Mixing ratio: 8:1 (By Weight).
Weigh components accurately and stir mechanically for 3 – 5 minutes.
Thinner content should not exceed 30% of the total mixture.
Application
Apply using a brush or roller.
Single-coat thickness: 40–60 μm.
Apply 2–6 coats depending on operating conditions. Consult PodLee agents for specific requirements.
Minimum recoating interval: 3 hours.
Coverage
Based on a 80 μm thickness: 1 kg kit will cover 6.25 m² (67 ft²).
Pot Life After Mixing
50℉ (10℃) – 3 h 70℉ (25℃) – 2 h 104℉ (40℃) – 1 h
