The distinction of 1.4 coating and lacquer and connection
Although the topic about “ coating and paint ” already was talked about old. Still have no an unified, science, standard up to now limit. Be opposite inside course of study “ coating ” and understanding of “ paint ” are unified all the time, there is the term level of “ coating ” only in the term clause of national level however. And the term standard that does not have “ paint ” or “ lacquer ” . And the outside paints to “ coating ” and “ inside the course of study of understanding much unlike of ” in that way, they often come to both cent rift, think “ coating ” is different from “ paint ” , it is two kinds of different products.
The as disparate as two kinds of the outside understanding inside course of study not only the disorder that creates commodity character, also cause the disorder of industry property. Have more very person, allegedly some local government press “ paint ” combustible explode easily danger is tasted give strict control, and “ coating ” is not tasted with danger try to manage. Then, a few newly-built paint manufacturer begin to get the chance of policy, what produce obviously is solvent lacquer, but “ does not name paint factory ” when building a factory to name, and name wait for ” of company of ” of “ paint factory or paint of “ special type. This is the flaw on the government that causes because of the disorder of basic idea really.
Somebody thinks coating is coating of ability in swimming, it is cheap coating, and paint is high-grade, it is a kind of wrong understanding actually, old times paint says paint, because inchoate coating basically is,be main raw material with grease and natural colophony.
