Main ingredients: tung oil (has a strong smell when used indoors) and linseed oil.
The ingredients of the wax are paraffin (gasoline is used as the solvent, but it needs to be heated, and it is dangerous without professional equipment), rosin, modified rosin, etc. Just forget about those that are too expensive or difficult to buy (solvents can be used without Hydroalcohol) such as beeswax and palm wax can also be used if convenient
In addition to lead, calcium, cobalt, manganese, zinc and rare earth desiccants, the drier is basically allowed to dry both inside and outside at the same time.
The proportion of oil is 60%, wax is 8%, drier is 2%, and solvent is 30%. The ratio is not absolute. The synthesis process is adjusted according to the viscosity and drying speed. First, boil the drying oil to a certain extent, and control the temperature and time, mainly dry the water and allow all nutrients to be carbonized, stop heating, add wax to dissolve it, lower the temperature to about 100 degrees, add desiccant, quickly cool and add solvent.
