Abstract
A method of agglomerating nanoparticles to form larger agglomerates is shown. The nanoparticles are mixed with a resin to form a first mixture (803) of agglomerates, having sizes over a range that includes agglomerates considered to be too large, suspended in the resin. A bead milling cylinder (802) produces a second mixture (808) with fewer large agglomerates. A filter (1001) removes the remaining large agglomerates. The resulting mill base is cut with a solvent before deployment.
Claims11
A method of agglomerating nanoparticles to form larger agglomerates, comprising the steps of:
- mixing said nanoparticles with a resin to form a first mixture of agglomerates suspended in said resin, said first mixture comprising agglomerates having a largest dimension which is greater than a predetermined specified dimension;
- bead milling said first mixture to produce a second mixture with a reduced number of agglomerates having said largest dimension greater than said predetermined specified dimension;
- and
- filtering said second mixture to produce a third mixture of agglomerates suspended in said resin, wherein substantially none of said agglomerates have a largest dimension greater than said predetermined specified dimension;
- wherein said first mixture comprises a percentage by weight of nanoparticles to resin of substantially three percent.
