    Catalysts

    Catalysts speed up the curing process of coatings, improving chemical resistance, durability, and hardness for professional-grade finishes. They help maximize shop productivity by reducing drying times without compromising quality.

    What is a catalyst in wood finishing?
    It's a chemical additive that accelerates the hardening of finishes like lacquers and polyurethanes for enhanced performance.
