Expert QA on TiO₂ – Weather-Resistant Pigment for Paints & Coatings
-
Q1: What is the crystalline type of TiO₂ most suitable for weather-resistant coatings?
A: The rutile crystalline form is favored for its superior UV stability, higher opacity, and greater resistance to weathering in exterior coatings, compared to anatase. -
Q2: What surface treatments are applied on weather-resistant TiO₂ pigment?
A: Inorganic treatments (silica, alumina) and organic coatings (polyols, silanes) are utilized to enhance dispersion, gloss, and resistance to chalking and water uptake. -
Q3: Which standards define TiO₂ pigment quality?
A: Global standards include ISO 591, ASTM D476, EN 12878, and GB/T 1706, which specify parameters like whiteness, tinting strength, pH, and moisture. -
Q4: How does TiO₂ improve UV and weather resistance?
A: The rutile structure absorbs and scatters UV radiation, shielding the paint matrix from photodecomposition and inhibits moisture ingress, critical for exterior coating longevity. -
Q5: What typical dosage is used for premium weather-resistant coatings?
A: Dosage varies, but high-durability exterior paints commonly utilize 18–30% TiO₂ by weight, depending on formulation and end-use. -
Q6: Are there environmental/safety concerns for TiO₂ use?
A: Leading manufacturers conform to REACH, RoHS, and other safety certifications, and modern TiO₂ grades are non-toxic and environmentally benign when used in paints/coatings. -
Q7: How is dispersibility and compatibility ensured in different paint systems?
A: Surface modification and controlled particle sizing optimize dispersibility, making pigments compatible with acrylic, epoxy, polyurethane, and alkyd resin systems.
