What is the difference between sheet metal ash and putty ash used in general automotive sheet metal parts?

At present, the development of industrial paint in my country is very rapid. When using industrial paint, sheet metal ash and putty ash are always used. Do you know the difference between these two substances?

Sheet metal ash: It is an oil-based paint, which can be directly scraped or used with other varnishes and topcoats, and is widely used on metal and wood surfaces. It has some excellent properties, such as fast drying speed, easy to scrape, high temperature resistance, no cracking phenomenon, good adhesion, can closely fit with the primer, good flexibility, can not be used when using sheet metal ash Add banana water, otherwise it will cause the coating to blister and crack. Now the sheet metal ash on the market is also used in summer and winter, we have to choose the suitable sheet metal ash according to the season.

Putty: It is a kind of polymer material, which is relatively delicate and has a strong taste. It belongs to water-based paint. It is mainly used to repair dents and cracks on sheet metal. It can also be used in construction machinery manufacturing, train and passenger car manufacturing, and Repairs of various metals and buildings are filled on it. When putty is used, the surface of the object to be coated should be cleaned and polished before it can be used.

The above is the difference between sheet metal ash and putty ash introduced by automobile sheet metal parts manufacturers. They are still the same in most aspects. Now there are many fake and inferior products on the market. It is a product produced by a regular manufacturer, so that it can be used safely and with confidence.
