FAQ
Lamellar talc particles orient parallel to the substrate surface during film formation, creating a tortuous path that significantly reduces moisture, oxygen, and ion permeability (barrier effect). This physical barrier mechanism directly enhances corrosion protection in epoxy and alkyd primers.
