SR-237 Rutile Titanium Dioxide with Silicon-Aluminum Inorganic Coating for High Hiding Power in Water-Based Coating Systems

SR‑237 is a versatile rutile‑type titanium dioxide pigment processed with silicon‑aluminum inorganic coating combined with organic surface treatment. The silicon‑aluminum inorganic coating layer greatly improves the pigment's outdoor weather resistance and photochemical stability, effectively delaying powder chalking and color fading of end‑products under long‑term ultraviolet irradiation.

Subsequent organic surface modification optimizes particle dispersion effect, significantly reduces agglomeration among powder particles. This grade possesses favorable optical performance, outstanding whiteness and high hiding power. It shows superior compatibility in various water‑based systems, delivers stable dispersion effect, and can satisfy long‑term anti‑aging requirements of water‑borne coatings and related downstream products.

SR‑237 is specially developed for water‑based coating systems. It is widely applicable for interior and exterior water‑borne architectural coatings, water‑based industrial paints and other water‑borne formula systems.

Benefiting from excellent weather resistance and stable water phase dispersibility, this product can effectively reduce flocculation phenomenon in water‑based slurry, maintain stable hiding power and color rendering performance, and guarantee the comprehensive performance of finished coating films in long‑term outdoor exposure environment.

• Packaging specification: 25 kg full‑paper bag for small package; 500 kg or 1000 kg PP woven bag for jumbo bag
• Store in dry, cool and well‑ventilated warehouse
• Keep away from rain, moisture and direct sunlight
• Control stacking height properly to avoid package damage caused by excessive compression
• During transportation, prevent sharp‑object piercing and heavy extrusion
• Do not mix and transport with other chemical raw materials
• Operate with care to avoid bag breaking and powder scattering

All data listed above are typical test values for reference only, not treated as guaranteed index for each batch. Raw material fluctuation, production equipment difference and processing condition change will cause practical performance deviation. A pre‑production trial test before mass production is strongly recommended to verify product adaptability to your production system, processing formula and end‑product requirements.
