1、 Definition and Composition

Sheet metal putty, commonly known as putty or unsaturated polyester resin putty, is a rapidly developing filling material in the past 20 years. It is mainly made by mixing and grinding unsaturated polyester resin, talcum powder, styrene and other materials, and also added with anti rust pigments and special additives. Sheet metal ash is an upgraded version of atomic ash with superior performance.

Atomic ash: also known as unsaturated resin putty, is made by mixing and grinding unsaturated resin, talcum powder, styrene and other materials. It is a two-component filling material that needs to be mixed with a curing agent for use.

2、 Physical properties and applications

physical property:

Sheet metal ash: belongs to oil-based paint, with fast drying speed, easy scraping, high temperature resistance, strong adhesion, good flexibility, and no cracking phenomenon. Has good rust prevention performance and can be directly used on bare metal surfaces, effectively preventing metal rusting; Good filling performance, strong adhesion to the substrate, high temperature resistance, smooth coating, and good compatibility.

Atomic ash: belongs to water-based paint, with fine gray matter, easy to scrape, fill, polish, fast drying speed, strong adhesion, high hardness, not easy to scratch, good flexibility, heat resistance, and not easy to crack or bubble. Mainly used for repairing dents and cracks on sheet metal, it can also be used in engineering machinery manufacturing, train and bus manufacturing, as well as repairing and filling various metals and buildings.

Purpose:

Sheet metal ash is widely used for direct scraping of metal and wood surfaces, or in combination with various primers and topcoats. It has applications in automotive repair, furniture, molds, concrete and concrete structures, as well as various metal products, wooden products, fiberglass products that require filling and repair.

Atomic ash is widely used in the manufacturing of trains, ships, buses, engineering machinery, machine tool equipment, automobile repairs, furniture, molds, concrete structures, and various metal products, wooden products, fiberglass products that require filling and repair.

3、 Precautions for use

Sheet metal ash: Banana water should not be added during use, otherwise it may cause coating bubbles, cracking and other phenomena. Choose suitable sheet metal ash products according to the season.

Atomic ash: Before use, the surface of the coated material should be washed clean and polished, otherwise it is prone to cracking. When used, it needs to be mixed evenly with the curing agent in a certain proportion.

4、 Price

-Sheet metal ash: Due to its special properties such as rust prevention, as well as factors such as production processes and raw material costs, its price is relatively high.

-Atomic ash: Its relatively low price makes it widely used in situations where rust prevention performance is not required and cost control is strict.

5、 Summary

There are significant differences between sheet metal ash and atomic ash in terms of definition, composition, physical properties, applications, and usage precautions. As an upgraded version of atomic ash, sheet metal ash has superior performance and a wider range of applications. When choosing to use it, the selection should be based on specific needs and actual situations.
