Product Category: Coatings Additives
Hyperdispersant - Solvent Systems
Dispersing agents are used extensively in the coatings industry to help disperse solid particles into a liquid medium.
Dispersing agents perform by the anchoring of the surfactant onto the particle substrate and then acting as a barrier to stop re-agglomeration of the particles. This concept is often referred to as steric stabilisation. The new hyperdispersant has three functions:
-
A powerful amine anchoring group that latches onto the pigment substrate
-
A tail section that floats within the solvent medium
-
A capping group that further enhances steric hindrance between pigment particles
-
Lansperse SL18 is 35% active to help ease of handling
