Application
Lithopone B301 is a versatile white pigment used in multiple industries:
● Coatings & Paints: Provides high whiteness, excellent hiding power, and good weather resistance in interior and exterior coatings.
● Inks: Enhances brightness and print durability in various printing inks.
● Rubber Industry: Acts as a reinforcing agent, improving mechanical strength and anti-aging properties of rubber products.
● Plastics & Masterbatches: Used as a filler and opacifier to enhance UV resistance and whiteness in plastic products.
● Paper & Textiles: Improves opacity, brightness, and printability in paper coatings and textiles.
Storage & Safety
● Store in a cool, dry, and ventilated area, away from moisture and direct sunlight to prevent clumping.
● Avoid contact with strong acids to prevent H₂S gas release.
● Use proper protective gear (masks, gloves) when handling fine powder to avoid inhalation and skin irritation.
