Abstract
This present invention relates to compositions and methods of enhancing the dispersion of nanoparticles. In certain embodiments, the compositions and methods can be used for enhancing the performance and/or longevity of primers using biochemical-producing microbes and/or byproducts synthesized by the microbes. In certain embodiments, the addition of biosurfactants can enhance the dispersion of pigments and/or other nanoparticles, as well as inhibition of stain or color bleeding through the primer.
Claims18
A method for dispersing nanoparticles in a primer, said method comprising:
- adding to the primer a nanoparticle composition comprising a biosurfactant that is a glycolipid and one or more primer components wherein the nanoparticle composition comprises positively and negatively charged nanoparticles at a ratio of a 1:10 to 10:1, positively charged to negatively charged;
- applying the primer to a surface;
- and
- applying a paint over the primer, wherein the primer is formulated with the biosurfactant to prevent color bleeding through the primer.
