WURTH ZINC RICH WELD THRU PRIMER 400ml

Zinc Rich Weld Thru Primer contains 98-99% pure zinc. It protects steel 
by sacrificial or galvanic action. The inclusion of epoxy resins and 
special binders promtes good adhesion to clean metal surfaces.  When 
dry, it produces a tough semi-flexible grey finish. It can be applied over 
pitted or rusted surfaces provided that all loose scale is removed. 

The electrical conductivity of this primer is high, and can be applied to 
metal interfaces prior to mig or spot welding. The zinc melts, and will 
fuse to the surface of the steel, reducing the formation of rust and rust
creep.

Can be welded through immediately after application.
