The search for acceptable alternatives to toxic chemical additives in alkyd paints, especially the antiskinning agents
and the cobalt drier catalysts, has recently become a subject of intense industrial and academic interest.
Largely in Europe, Ascinin[R] AntiSkin antiskinning agents
serve as methylethyl ketoxime alternatives and Borchers[R] Dry driers find use as replacements for cobalt-based products.
This implies that the system will either not need antiskinning agents
or will need much less than cobalt-based systems.
Cytec Surface Specialties, which recently acquired the Surface Specialties business of UCB, provides a broad and deep portfolio of additives: pigment wetting and dispersing agents, flow and leveling agents, defoamers, adhesion promoters, catalysts, UV light stabilizers, preservation and curing additives, rheology modifiers, driers, antiskinning agents
, antistatic agents, and antioxidants.
