3. Product Characteristics
SR-235 stands out for its high whiteness, high hiding power, medium durability and good dispersibility. The absence of inorganic and organic coatings ensures its compatibility with diverse formulation systems, while its high TiO₂ and rutile content lay the foundation for excellent opacity and color performance. The low loss at 105℃ and minimal water-soluble content guarantee stable performance in high-temperature and water-based application environments, and the fine residue index ensures uniform dispersion in coatings and paper.
4. Application Fields
Thanks to its comprehensive properties, SR-235 is widely applied in:
• Traffic paints: Delivers durable and high-whiteness coloration for road traffic marking products.
• Primer paints: Provides strong hiding power to enhance the coverage and adhesion of primer coatings.
• Masterbatch: Ensures uniform color dispersion and stable color performance in plastic masterbatch production.
• Paper: Improves the whiteness and opacity of paper, meeting the quality requirements of high-grade paper products.
5. Classification & Packaging
SR-235 complies with international standards including ISO591-1:2000(E) (R1 grade) and ASTMD476-00 (II, III grades), ensuring its global market adaptability. For packaging, it is available in 25kg full-paper bags, 500kg and 1000kg PP woven bags, meeting the procurement demands of small-batch processing and large-scale industrial production.
In summary, SR-235 uncoated rutile titanium dioxide combines high-quality raw material indicators with stable application performance, making it a cost-effective and reliable pigment solution for coatings, masterbatch and paper industries.
