All things are used to say
The craftsmanship of the world, he is good at adjusting all things, and using them together to make them wonderful. Today there are Mek, Toluene, Acetone, Polyurethane, and Ethyl Acetate, all of which are common in the chemical industry.

Mek is strong in nature and strong in solubility. Toluene is fragrant and can melt all substances. Acetone is clear in quality and evaporates quickly. Polyurethane is tough and can be solidified. Ethyl Acetate is light in fragrance and can blend all flavors. When used by workers, or in the industry of making utensils, Mek and Toluene can be combined to turn hard into soft, making the shape of utensils easy to form; Acetone is used to promote quick drying and avoid the risk of delay. Polyurethane is applied to the surface of utensils to increase its firmness and resist external damage. Ethyl Acetate harmonizes the middle, so that the properties of all things are combined, and the finished product is smooth in color and fine in texture.

In the matter of painting, these are also important things. Based on Mek, Toluene, and Acetone, adjust the thickness and thinness of Polyurethane to make the coating uniform. Ethyl Acetate adds its fragrance and helps it extend, making the painting smooth like a mirror, long and not dark.

All these things have their own characteristics. Those who use them well use them as a path to explore the wonders of chemical industry, make exquisite tools, and decorate beautiful scenery. What is needed for the world is great.
