Rutile TiO2 R972 CAS 13463-67-7 for Offset Printing Ink
Rutile TiO2 R972 is dedicated rutile titanium dioxide specially formulated for offset printing ink. With alumina‑silica inorganic‑organic composite surface treatment and precise particle‑size classification, it owns proper oil absorption value and excellent wetting performance in offset ink oil‑based resin system. It disperses evenly during three‑roller milling process, delivers high hiding power and pure white tone. It shows good compatibility with offset ink alkyd resin, rosin modified resin,
Product Overview
Rutile TiO2 R972 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide optimized for lithographic offset printing ink. Strict particle‑size control brings matched oil absorption for offset ink formula. Special surface modification improves affinity with oily ink binders. This grade solves common offset ink industry pain points including poor milling dispersion, abnormal emulsification, insufficient opacity and unstable dot reproduction. Consistent product quality adapts to mass three‑roller milling and offset ink manufacturing.
Key Features
- Suitable oil absorption value, match offset ink oily resin system, lower risk of ink emulsification.
- Excellent oil‑phase wetting and dispersion, obtain good milling effect by three‑roller mill.
- High hiding power and tinting strength, achieve bright whitening effect for offset printed patterns.
- Good compatibility with alkyd resin, rosin resin, soybean oil and other offset ink raw materials.
- Low coarse particle content, reduce printing plate wear and surface speckle defects of printed matter.
- Stable chemical inertness, keep balanced ink‑water balance during offset printing process.
Main Applications
‑ Sheet‑fed offset printing ink for paper packaging and publication‑ Web offset lithographic printing ink‑ Offset white ink and spot‑color tinting ink‑ Lithographic ink for label and commercial printing‑ Other oil‑based offset printing systems requiring white pigment
Usage Recommendation
‑ Recommended dosage: 10‑28 wt% in finished offset ink, adjust based on opacity and whiteness requirement.‑ Premix pigment with offset ink resin and oil, then adopt three‑roller mill for repeated milling dispersion.‑ Control milling fineness to meet offset ink technical specification.‑ Pay attention to ink‑water balance adjustment during printing application.‑ Carry out small‑batch ink trial preparation and printing test before 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.
