STOPAQ® FN 4200 protects the space between the flange plates against the ingress of moisture, and penetrates the pores of the steel. Once applied the product stays flexible forever and shows no degradation after many years of service.
STOPAQ® FN 4200 is suitable for coating above-ground flange plates having thermal deformations and gives applicators an opportunity to coat uneven, unclean or hard-to-access surfaces. When applied STOPAQ® FN 4200 does not flow from vertical and 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.
