| Résumé : |
Boosting colour strength is on the forefront of coating formulators’ and manufacturers’ minds. However, for many systems, improving colour performance has been a difficult task. Whether it is a ready-made dispersion or a fully formulated system, large adjustments to a formula can be unfeasible due to manufacturing, volatile organic compounds (VOCs) or consumer restraints.
Borchers' technology allows for the post-addition of an additive to improve colour acceptance, colour strength or quality of a pigmented system. A simple addition of a colour booster or compatibiliser to the base will result in a stronger, cleaner and more chromatic colour, which can be seen in tints with a variety of difficult pigments. Additional benefits include a reduction or elimination of colour rub-out and improved compatibility of universal waterborne systems used in solventborne bases. |
