Features
Bitumastic 300M is the most specified coal tar epoxy in the
world. Why do applicators prefer 300M over other coal tar epoxies? It combines the
superior moisture resistance of coal tar with the excellent chemical and abrasion
resistance of epoxy. This two-component chemically cure product is formulated to be
applied at thicknesses up to 35 mils in one coat. In most cases, one coat of Bitumastic
300M will do the work of two or more coats of conventional coal tar epoxy. It meets all
requirements of the Corps of Engineers specifications C200 and C200A.
Typical Uses
Bitumastic 300M is designed to be applied at relatively
high thicknesses for the economical protection of steel, concrete and other suitable
surfaces of structures exposed to a variety of heavy-duty service conditions. Environments
include chemical plants, flood gates, locks and dams, sewage plants, bridge and piling
structures and pipelines. Also used for immersion service and in atmospheric conditions
where abrasion and chemical resistance are needed. Industries such as sewage and water
treatment, chemical processing, marine, offshore exploration, oil and gas distribution,
and public utilities all utilize this economical heavy-duty product.

Bitumastic
is a century-old trade name that is often associated with long-term protection
from water penetration. Typically made from coal tars and blends of resins such
as epoxy, these products have been used as tank linings, to coat the interior and exterior
of buried pipe, and to protect equipment subjected to water immersion.
