The SEQUION® range are extremely effective dispersants.
They can be used to reduce the viscosity of coatings and slurries and as dispersants for water based paints.
SEQUION®, have the required heavy metal chelation properties which allow for the control of heavy metals in case they would interfere with the stability of the paint
HYDRODIS® VN series represents an evolution of the general outline explained above, conjugating the characteristics of wetting agents with those of dispersing agents.
HYDRODIS® VN has an excellent sequestering ability, because of its chemical nature (sodium salt of poly-phosphonic acid). It an effective chelating agent towards calcium and magnesium ions. It can therefore control the hardness of the process water.
In the preparation of coating products HYDRODIS® VN allows to replace the usual combination of wetting/dispersing agents with the additional benefits of:
- lower viscosity of the coating product
- greater colors development of the pigment
- greater colouring force
- greater brilliance
