Stopgalv also known as “Galvastop” is a unique blend of synthetic resins which has been formulated to be an excellent masking agent on parts where no galvanizing is required.
Stopgalv is easily applied by paint brush or dip application on any component where no galvanizing is required. Left to dry for approximately 2 hours, the part can then go through the entire conventional process ie degreaser, acid, flux, zinc kettle and quench / passivate, after this all that will remain of the Stopgalv is an ash which is easily removed with a wire brush.
Stopgalv provides a very flexible coating which means that it will not chip or crack on parts being transported to the galvanizing plant which leads to zinc creeping underneath the coating.
Stopgalv has been successfully used on threads and close tolerance high pressure water pipes.
