Its quick curing,easy sanding and good flexibilities and adhesion allows its wide-st application in quick repair and maintenance
Special application is surface filling of automobiles,trucks,machine tools and shi-p-building and furniture,and also it has found good application in decoration of b-uildings
Application
Applied on Steel panel,iron panel,glass fiber,wooden,concrete wall and any painted metallic surface
Applicationmixing ratio
Putty :Hardener(by weight)=100:1.5-3
Note:Pot Life 5-7min (according to the temperature and ratio of Hardener)
Application reference
1. Completely remove the rust,oil dirt,water and so on from the surfaces,keep the coated surfaces clean before scraping.
2. The Putty and Hardener should be mixed completely to achieve the uniformity of colour.
3. The mixture of Putty and Hardener should be used up before gelling.
4. Scrape the mixture of Putty and Hardener into the spot defects which will be fi-lled and scrape to evenness immediately.
5. In case of scraping of thick coat.it is preferable to apply in thin coats for s-everal times till reaching the obiective thickness.
6. Sanding affer mixture is hardened(30-50min20¡æ) .

Notices
1. The mixed Putty must bi used up within the available period before gelling.or it will gel.
2. When there is air bubble while application,fully scrape to evenness with scraper to ensure good adhesion.
3. Containers which are opened must be carefully resealed,the Putty mixed with har-deners should not be returned to the original container. 4. Store in a cool place where the temperature is below 25¡æ,The shelf life is hal-f year..
