[polyethylene wax] The one effects of pigment dispersant on coating performance

Transparency is a characteristic of the coating film. The higher the transparency, the easier to see the bottom layer. The higher the hiding power, the stronger the hiding power to the bottom layer. The amount of light reflected and passed on the surface determines the hiding power or transparency of the paint.  polyethylene wax

The type of pigment and the degree of dispersion have an influence on this. Due to the influence of refractive index and particle size, the covering pigment has a greater influence on the reflected light. Polymer dispersants improve transparency by affecting pigment particle size distribution (more uniform and narrower). The addition of a polymer dispersant can increase the surface area (reducing agglomerates and reducing particle size), which can further increase the hiding powder.
