It is better not to use the NC Nitrocellulosic and the epoxy resin. Because both of them will produce a chemical reaction with bronze and generate a jelly; if these two kinds of resins are required to use, please use them as soon as possible.
Please try to use the resin with the acid value lower than 3. Because the lower the acid value system is, the better.

The aromatic and ester solvents and helpful for bronze powder particles to be wet and scattered comprehensively. Please avoid to use the alcohol and ketone solvents and acidification incomplete lipid solvents.
