Accurate Liquid Color Dosing

The best of the best gravimetric solid colorant systems claim to dispense colorants with a high degree of accuracy.

ColorMatrix advanced liquid colorant, in conjunction with our proprietary volumetric liquid dosing systems, offer even greater dosing accuracy, down to addition rates as low as 0.001%.

This means that you only use precisely what you need. ColorMatrix liquid dispersions incorporate more effectively into the polymer achieving higher quality, more consistent color distribution and superior aesthetic characteristics.

Dosing accuracy Case study

A head-to-head colour trial at a global packaging producer

The trial included a series of dosing accuracy tests to compare precision shot-to-shot consistency between ColorMatrix liquid color dosing and a high performance solid colorant system

Transparent blue liquid, LDR = 0.035% deviation from target LDR

 Dosing accuracy Case study

Transparent blue solid, LDR = 0.032% deviation from target LDR

• Inherent accuracy of volumetric liquid system gives greater control over shot-weight fluctuation
• Parts made using liquid system show less variability and greater color consistency
• Easy, reliable, accurate colorant dosing
• Unlike gravimetric systems, volumetric liquid feeders are generally more robust and unaffected by environmental disturbances eg. vibration
