Rutile TiO2 R931 CAS 13463-67-7 High Dispersion for Water Based Ink
Rutile TiO2 R931 is dedicated rutile titanium dioxide specially developed for water‑based ink. Adopting alumina‑silica inorganic‑organic composite surface modification, the pigment obtains superior hydrophilic wetting property. It can be rapidly dispersed in aqueous resin systems without severe agglomeration. It features high hiding power and clean whiteness, forming smooth ink film after printing. It shows good compatibility with water‑based acrylic resin, polyurethane resin and various water‑s
Product Overview
Rutile TiO2 R931 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide with water‑system‑oriented composite surface coating. Optimized surface treatment enhances hydrophilicity and anti‑flocculation ability in aqueous medium. This grade solves typical pain points of water‑based ink industry including hard‑to‑disperse pigment, easy sedimentation, flocculation and poor ink‑film smoothness. Reliable quality adapts to mass production and bead‑mill grinding process of various water‑based printing inks.
Key Features
- Excellent hydrophilic dispersion performance, easy wet‑out in water‑based resin, shorten ink grinding time.
- High whiteness and tinting strength, achieve bright whitening effect for water‑based printed layers.
- Good anti‑sedimentation and anti‑flocculation property, improve long‑term storage stability of aqueous ink.
- Low coarse particle content, reduce pinhole and spot defects on printed ink film.
- Great compatibility with acrylic, polyurethane and other mainstream water‑based ink resins.
- Low heavy‑metal impurity, meet environmental requirement for water‑based packaging printing ink.
Main Applications
‑ Water‑based flexographic printing ink‑ Water‑based gravure packaging ink for paper and film‑ Environmental friendly aqueous printing ink for labels‑ Water‑based surface printing varnish‑ Other aqueous printing systems requiring high dispersion white pigment
Usage Recommendation
‑ Recommended dosage: 8‑24 wt% in finished water‑based ink, adjust according to opacity and whiteness target.‑ Premix pigment with water, water‑based resin and dispersant, then process by bead‑mill for fine grinding.‑ Adjust pH value reasonably to maximize dispersion stability.‑ Avoid oil contamination during production process.‑ Complete small‑batch ink making and printing test before formal mass production.
Storage & Packaging
‑ Packaging: 25kg moisture‑proof kraft paper bag with PE inner liner.‑ Storage: Store in dry, cool and ventilated warehouse, keep tightly sealed against moisture absorption.‑ Shelf life: 24 months under standard storage conditions.
