STOPAQ FN 4200 is corrosion preventative filler which is applied for the protection of above ground flanges and voids. It protects the space between the flange plates against the ingress of moisture and oxygen. Once applied the product penetrates the pores of the steel and stays flexible forever and shows no degradation after many years of service.
STOPAQ FN 4200 is suitable for coating above ground flange plates and gives applicators an opportunity to coat uneven, non-cleaned or hard to access surfaces. When applied STOPAQ® FN 4200 does not flow from vertical or inclined surfaces.
STOPAQ FN 4200 has excellent resistance to weathering and ageing and will protect the flange internally.(nuts and bolts) over a long period of time to provide a largely maintenance free protection system for above ground flanges.
