Our teacher wrote an artistic signature and drew a pattern on our clothes with acrylic. The landlord can draw a draft with any pen, and acrylic can be used as a side paint without any requirements. You should pay attention to the fact that propylene is insoluble in water but soluble in ethanol. It is forbidden to mix with oxidants and acids to prevent sun exposure. Stay away from fire and heat sources. If you smell too much propylene, you will feel dizzy, and your eyelids will flush, shed tears and cough. The main regulator for coloring propylene pigment with propylene has high water content. You can use ordinary oil painting pen, painting knife, porcelain brush, watercolor pen, blackboard brush, sponge, loofah and so on. The palette and pen are mostly made of non-absorbent containers such as ceramics, glass and enamel to prevent them from being cleaned. Acrylic pigments will dry immediately after the water evaporates, so when painting, you should know the procedure to make the strokes naturally connect and achieve the desired effect.
