Lansperse SL18-HA

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-HA is a 100% active product.
