Product Overview

QK3310 is a 100% active polymer dispersant for organic pigment, carbon black and inorganic pigment. It is aimed at epoxy and UV systems and at highly polar formulations generally. Two things define it: it does not cause resin crosslinking, which is the usual failure mode for reactive dispersants in epoxy and UV, and its resistance to floating and flooding is very good.

Key Benefits

100% active, so no solvent is carried into a solvent-free or UV formulation
Does not cause resin crosslinking, which keeps pot life and cure predictable
Excellent resistance to floating and flooding in mixed shades
Broad resin versatility and stability
Handles organic pigment, carbon black and inorganic pigment in the same system

Floating and flooding streaks in mixed shades
Adding solvent to a formulation that is sold as solvent-free

Application Scenarios

Epoxy floor and tank lining systems
UV-cured coatings and inks
Highly polar solvent-free formulations
Mixed shades where floating shows as streaking

Recommended Dosage

All dispersant and additive dosage figures below are quoted exactly as the source data sheet quotes them. Dispersant figures are percentages on pigment weight, not on the total batch. The published values are empirical, so confirm the optimum with a dosage ladder in your own system.

Inorganic pigments	2-5%
Organic pigments	10-20%
Titanium dioxide	2-4%
Carbon black	20-30%

Use Guide

Add during the grinding process. The recommended amount is a percentage of the pigment added.
Store in a cool dry place; shelf life is two years in the unopened original container.
Confirm pot life in a two-component epoxy before committing a production batch.

Quality Control On Your Side

Check pot life and cure on the full two-component system, not on the mill base alone
Rub-out test on mixed shades to confirm anti-float performance
Verify colour strength against reference at the set dosage

Comparison

How It Compares With The Alternatives

Technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named commercial product.

QK3340	QK3340 is 45% active in PMA for alkyd and acrylic; QK3310 is 100% active for epoxy and UV.
QK3740	Both are 100% active; QK3740 is written for waterborne systems, QK3310 for epoxy and UV.
Reactive dispersant	Does not cause resin crosslinking, so pot life and cure stay where the formulation put them.

Questions

QK3310 Solvent-Free Polymer Dispersant Questions

Will QK3310 affect epoxy cure?

The data sheet states it will not cause resin crosslinking and has high safety performance. Confirm pot life on your own two-component system before production.

Which systems is it mainly recommended for?

Epoxy systems and UV systems, and highly polar systems generally.

How is dosage calculated?

As a percentage of the pigment added during the grinding process.

What is the shelf life?

Two years from the production date when stored unopened in a cool dry place.
