Characteristics
The substrates such as galvanized iron,aluminum and some alloys are prone to oxidi-ze and from a compact film of oxidization due to strong activity of metal.The conv-entional putties don't harden completely on the surface of substrates resulting in poor adhesion.
YK-630 Putty is prepared by DCPD modified UPR with reactivity. It exhibits good ad-hesion,quick curing,and sanding properties without existence of minimumshrinkage on the surface of metal substrate such as galvanized iron and aluminum by introduction of BPO curing system
Application
Applied on galvanized iron panel,aluminium panel,Steel panel,ironpanel,galvanize glass fiber,seam welding,and any painted metallic surface

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(20-40min20¡æ) .
7. Sanding paper
