Question: I need a polysilazane-based coating for my project. How do I choose the right one?

Answer: Your choice depends on three critical factors:

1. Temperature Resistance: What is the maximum operating temperature?

2. Curing Process: Can you apply heat, or must it cure at room temperature?

3. Primary Function: What is the key property you need? (e.g., hydrophobicity, ease of cleaning, ceramification)
