Resins

Rosin modified phenolic resins

Phenolic resins across the viscosity and tolerance range, for coldset, sheetfed, and heatset inks.

Rosin modified phenolic resin manufactured by Viscus Oils

Specified by viscosity and tolerance.

In practice a phenolic resin is chosen on two counts: how thick it runs and how much solvent it will hold. Those two settle gel response, gloss, water balance, and how fast the ink sets on the press. We make the range across both axes rather than one general grade.

Also sold as rosin-modified phenol-formaldehyde resin, rosin-phenolic resin, and phenol-rosin resin.

Variations we develop

Six positions across the viscosity and tolerance range, each aimed at a different press condition.

Low viscosity, high tolerance

Excellent wetting, for high loading of pigments.

Moderate viscosity, high tolerance

Good wetting at higher molecular weight. Mainly coldset and sheetfed inks.

Moderate viscosity, good tolerance

Webfed coldset, sheetfed, and heatset inks, with good gloss.

High viscosity, high tolerance

For very high speed machines. High gel response, excellent gloss and water balance.

High viscosity, high molecular weight

High structure and faster setting for heatset and sheetfed inks, with very good water balance and solvent release.

High molecular weight, excellent tolerance

Sheetfed inks, contributing high gloss and excellent printability.

Specifications, pricing, or a custom grade

We develop to a target viscosity, tolerance, and gel response.

Where these are used

Coldset inks

Newsprint and web work, where fast setting carries the run.

Sheetfed inks

High gloss and printability on coated stock.

Heatset inks

High structure grades with good solvent release.

High speed presses

High gel response and water balance at machine speed.

Partnerships

How we work

Three ways customers buy from us, and all three apply to every grade on this page.

Regular supply

Batch-tested supply of the grades listed here, with a COA on every shipment.

Custom development

Grades developed to your specification, including Indian-made equivalents to imports.

Job work and tolling

We manufacture to your formulation, on our plant and our quality systems.
