,Precautions

1Resin and solvent

The nitrocellulose and epoxy resins should be avoided. because both will chemically react with copper to form a jelly.

Avoid using alcohols and ketone solvents and lipid solvents with incomplete acidification.

Aromatic solvents and ester solvents help to completely wet the bronze powder particles to achieve full dispersion.

High-purity resins and solvents (low water content) should be used. If there is a small amount of water, it is recommended to use molecular sieve to remove water before adding bronze powder pigment.

2Dispersion

Add the bronze powder first, and add 1:1 or 2:1 solvent to the bronze powder several times under slow stirring.

Stir under low shear for about 15 minutes to a paste.
