TAR, BITUMINOUS Chemical compatibility with O-rings, rubbers, & plastics

Bituminous tar is a dark, sticky substance derived from the distillation of coal tar or petroleum, used primarily as a binder in road construction, roofing, and waterproofing applications. It is employed in the production of asphalt, providing durability, flexibility, and resistance to weathering and chemical damage. Bituminous tar is also used in the manufacturing of roofing materials, sealants, and coatings, offering excellent waterproofing properties. Proper handling and storage of bituminous tar are essential to prevent accidents and ensure safety, as it is flammable and can pose health risks if inhaled or ingested. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with bituminous tar. Its effectiveness as a binder and waterproofing agent makes bituminous tar a valuable product in numerous construction and industrial applications, contributing to the durability and longevity of roads, roofing materials, and other structures.
