TiO2 R794 is paper‑special rutile titanium dioxide developed for high‑opacity printing paper. Through alumina‑silica inorganic‑organic composite surface modification and precise particle‑size classification, it possesses excellent opacity and bright whiteness. The pigment shows favorable retention performance in paper pulp, disperses homogeneously in wet‑end papermaking system. It effectively boosts covering performance, brightness and printability of printing paper, reduces show‑through phenome

Product Detail

Product Overview

TiO2 R794 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide tailored for high‑opacity printing paper. Optimized particle distribution maximizes light‑shielding capacity. Composite surface treatment improves wettability and retention in aqueous pulp medium. This grade addresses typical papermaking challenges including insufficient opacity, print‑through, low pigment retention and uneven sheet brightness. Steady quality fits large‑scale wet‑end dosing production of printing paper.

Key Features

Excellent hiding power, greatly improve paper opacity and restrain print‑through show‑through defects.
Good retention in pulp, cut down pigment loss and lower comprehensive production cost.
Uniform dispersion inside pulp, avoid speckles and ensure consistent brightness across paper sheet.
Promote paper surface smoothness and ink‑absorbing performance, upgrade overall printing effect.
Good compatibility with pulp fiber, sizing agent, retention aid and other papermaking auxiliaries.
Stable chemical property, will not bring adverse effect on paper forming and post‑processing.

Main Applications

‑ High‑opacity offset printing paper

‑ Book and publication printing paper

‑ Magazine coated printing paper

‑ High‑grade copy and writing printing paper

‑ Other paper products demanding high opacity and excellent printing performance

Usage Recommendation

‑ Recommended dosage: 2‑10 wt% calculated on dry pulp weight, adjust according to target opacity requirement.

‑ Prepare well‑dispersed TiO2 slurry before feeding into pulp chest.

‑ Appropriately match retention aid system to promote pigment retention rate.

‑ Maintain pulp pH within standard papermaking scope.

‑ Complete small papermaking trial to test opacity and physical index before mass manufacturing.

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.
