Titanium Dioxide NTR-750 High Purity for Coating Applications
Product Overview
Titanium Dioxide NTR-750 represents the pinnacle of sulfate-process rutile technology, engineered to deliver unparalleled brightness with a distinct blue undertone. Designed for industries requiring superior optical performance and process stability, this pigment combines 94% minimum TiO₂ purity with advanced surface characteristics. Its unique balance of low oil absorption (20 g/100g) and exceptional Reynolds Index (1,900) makes it the ideal choice for formulations demanding maximum opacity with minimal viscosity impact. Certified for use in coatings, plastics, specialty papers, and food-contact packaging, NTR-750 sets new benchmarks in whiteness (CIE L* 98.5) and weather resistance (ASTM D476 Class 2, 3, 4 compliance).
