TiO2 R960 CAS 13463-67-7 Fine Particle for Printing Ink and Overprint Varnish
TiO2 R960 is ink‑special rutile titanium dioxide with precisely controlled fine particle size. Through alumina‑silica inorganic‑organic composite surface modification and strict classification treatment, it reduces coarse impurity particles. It can be quickly wetted and dispersed in ink resin and varnish systems, delivering bright whiteness and uniform color. It minimizes pinhole and speckle defects of printed layer and varnish film. It has good compatibility with various ink resins, solvents an
Product Overview
TiO2 R960 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide customized for printing ink and overprint varnish. Fine milling and rigorous classification guarantee fine particle distribution and low coarse impurities. Composite surface coating greatly improves pigment wetting capability inside resin carrier. This grade addresses common industry pain points including poor fineness, pinhole defects, uneven gloss and slow grinding dispersion. Reliable quality supports large‑scale bead‑mill grinding and continuous production of printing ink and overprint varnish.
Key Features
- Well‑controlled fine particle size, reduce pinhole and blemish defects on ink film and varnish layer.
- Outstanding wet‑out and dispersion property, shorten grinding cycle and improve production efficiency.
- High whiteness and clean color tone, deliver excellent whitening and tinting effect for ink and varnish.
- Low oversized particle content, ensure smooth surface for printed patterns and top‑coat varnish.
- Good compatibility with solvent‑based ink resins and overprint varnish raw materials.
- Stable chemical performance, enhance shelf‑life storage stability of finished ink and varnish.
Main Applications
‑ Gravure ink, flexo ink and general‑purpose packaging printing ink‑ Overprint varnish for paper, label and plastic film printing‑ Printing post‑processing surface protective varnish‑ Whitening and tinting formulations for printing auxiliary varnish‑ Printing materials requiring fine, smooth and glossy coating appearance
Usage Recommendation
‑ Recommended loading: 7‑22 wt% in printing ink; 3‑12 wt% in overprint varnish, adjust according to opacity and whiteness requirements.‑ Premix pigment fully with resin and solvent, then process by bead‑mill or sand‑mill for fine dispersion.‑ Strictly control grinding fineness to meet ink and varnish technical specifications.‑ Prevent moisture contamination to keep finished products stable during storage.‑ Carry out small‑batch trial formulation and printing test prior to 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.
