YK-650 Series | Plastic Putty Characteristics The reticulated structure gives Plastic Putty superior adhesion and flexibilities and e-asy-sanding surface. Special application is surface filling of PC.PVC.ABS and glass fiber. Application mixing 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 filled and scrape to evenness immediately. 5. In case of scraping of thick coat.it is preferable to apply in thin coats for several times till reaching the obiective thickness. 6. Sanding affer mixture is hardened(30-50min20℃) . 7.

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 hardeners should not be returned to the original container. 4. Store in a cool place where the temperature is below 25℃,The shelf life is one-year.
