VP 6700 Wetting and dispersing agent

The Wetting and Dispersing Agent (CAS No: 6700) is a high-performance industrial additive engineered to optimize the stabilization and distribution of solid particles within liquid media. In the field of industrial chemistry, this agent serves as a bridge between incompatible phases, significantly reducing the interfacial tension between the pigment or filler surfaces and the resin vehicle. By facilitating the rapid displacement of air and moisture from particle surfaces, it allows for more efficient mechanical de-agglomeration during the milling process. Beyond initial wetting, it provides robust stabilization through steric hindrance or electrostatic repulsion, effectively preventing the re-coalescence or flocculation of particles. This ensures a consistent, homogeneous dispersion that maintains its integrity over long storage periods. Its application is vital for achieving high-quality finishes where color development, gloss, and rheological control are critical requirements for the final product’s performance and aesthetic appeal.

Attributes

Key Features and Benefits

Accelerated Pigment Wetting: Significantly reduces grinding time and energy consumption by rapidly penetrating pigment aggregates.
