Dispersant is moisture-proof, impermeable plugging material and good bonding material, powder solidification type and delay type are gray powder. Dispersing agent NNO was divided into paraffins, metal soaps, low molecular waxes, fatty acids, aliphatic amides and esters. Dispersant is the additive of coating, which can improve the gloss of coating, prevent two-color head blossom, reduce viscosity, increase the loading capacity of pigment and so on. So what effect does dispersant have on coating?
The role of Dispersing agent NNO is to use wetting dispersant to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface characteristics of pigment particles, adjust the movement of pigment particles. Usually reflected in the following aspects:
1, the impact of gloss:
When paint gloss is high, particles can not exceed 5 microns, ink can not exceed 1 micron, polymer dispersants can reduce the paint formed by large particles, so as to improve the gloss of the paint.
2. Influence on transparency:
The higher the transparency of the paint, the easier the bottom looks, the higher the coverage, and the stronger the coverage at the bottom. Dispersants can make the distribution of coating particles more uniform and narrow, so that the coating is more transparent.
3. Impact on compatibility:
With good compatibility, coating manufacturers can produce a variety of resin products Dispersing system, Dispersing agent NNO can expand the range of use of paint, is critical to the production of mixed colored paint.
4. Influence on leveling:
Adornment paint often can see brush mark when stuccoing, this is paint lacks level off sex. Using dispersants can further stabilize pigment particles and improve fluidity.
5. Impact on output:
Output is the amount of paint and ink produced by a process. Dispersants can increase paint production by increasing pigment concentration. Appropriate addition of polymer dispersant can reduce the viscosity and increase the pigment content in the abrasive slurry, thus increasing the yield.
