BioLoop dispersing agent for both aqueous and solvent systems

Quick Links

BIO691 is part of our new range of powerful dispersing agents containing components that are from renewable sources. Unlike many bio-based surfactants, this product offers excellent wetting and dispersing properties for a wide range of inorganic and organic pigments and powders. One of the main characteristics that make them different from conventional dispersing agents is how they can attach to a particle substrate. Conventional dispersing agents tend to be linear in structure and attach with one hydrophobe group. The BioLoops are different in the respect that they have two hydrophobes that attach onto a particle substrate making it twice as effective as a conventional dispersing. What makes this particular product unique is the ability to disperse particles in both aqueous and solvent-based mediums. An aqueous dispersion manufactured using Lansperse BIO691 can be incorporated in both solvent and aqueous based paints without any detriment to performance. This property is useful for universal tinters whilst also useful for formulators that want a multi-functional dispersing agent.
