SURFCROP ® DF Series are derivatives of sulfonic acid which contain a naphthalene functional unit. They are produced on a large scale by condensation of naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde. Different grades have different molecular weights, varying degree of condensation and different properties, tailored for use in agrochemical formulations.
SURFCROP ® DF-HCD is a high molecular weight dispersing agent for use in WP and WDG formulations.
