Q1: What is the specific function of Component B in the two-part coating system?
A: Component B acts as the cross-linking agent (hardener). It chemically reacts with the resin in Component A to form a thermoset polymer network, which provides the coating with its final hardness, chemical resistance, durability, and adhesion. Without it, the coating would remain uncured and non-functional.

Q2: What happens if the mixing ratio between Component A and B is incorrect?
A: An incorrect mixing ratio can lead to severe performance issues: too much Component B may cause brittleness, poor flexibility, or surface defects; too little will result in incomplete curing, softness, poor chemical resistance, and reduced adhesion. Always follow the manufacturer's specified ratio precisely.

Q3: Are there special handling or storage requirements for Component B?
A: Yes. Store in a cool, dry, and well-ventilated area, tightly sealed to prevent moisture absorption and contamination. It is typically sensitive to moisture and may have a limited shelf life. Use appropriate PPE when handling. Once mixed with Component A, apply within the specified pot life and clean equipment promptly.
