Product Description
LS 6258 Fusion Bonded Epoxy Coating is a one-part, heat curable,
thermosetting epoxy coating
designed for corrosion protection of pipe. LS 6258 utilizes special ingredients
that promote superior adhesion to steel and epoxy novolac resins that
significantly raise the glass transition temperature of the coating. These
benefits make LS 6258 especially suitable as a single component internal
coating for OCTG applications.
