Washingtons law brings the number of Americans living in places where the coal tar sealants are banned to 8.7 million, according to the Coal Tar Free Americablog by Tom Ennis, an Austin city , coal tar epoxy banned
(1) the coal tar component of CTEs contains substances that can cause irritation or inflammation in the event of direct contact with the human body (skin contact, inhalation of emissions), mainly during processing. Job-related health damage cannot be ruled out as a result of long term contact.
Coal Tar Epoxies. Coal tar epoxy is not forbidden and as long as the precautions in the Material Safety Data Sheets are obeyed I think you are o.k. There are a lot of common paints for which workes must wear personal safety equipment for handling. I think nobody works for example without a breathing mask when painting with industrial paints.
It is now banned in the developed nations like US, Europe, Japan, etc. As the use of coal tar is being restricted, there is an urgent need to formulate a coal tar free epoxy product for corrosion, coal tar epoxy banned
Coal tar epoxy is made by the conversion of polyamide epoxy with a pitch of refined coal tar. It is mostly used on metal substrates and concrete in offshore, petroleum and industrial environments. The fluctuation of temperatures can make the product crystallize.
Coal tar epoxy is a protective coating consisting of tar, fillers, a gelling agent, and a curing agent. The substance wards off corrosion on equipment used in or near fresh or salt water. It is also resistant to some mild chemicals, acids, and alkali solutions in extreme environments. Epoxy resins , coal tar epoxy banned
This high-solids, polyamide-converted epoxy includes refined coal tar pitch and forms an extremely durable coating. Protects against severe abrasion, strong chemicals and immersion in water (non-potable) Ideal for use on steel, concrete and other surfaces in extremely corrosive environments.

If a top-coating of another epoxy is not black, multiple coats will be necessary to prevent bleed-through (discoloration) Substrate temperature must be 5F above dew point when applying Coal Tar Epoxy #209. For best results, apply with a 1/4' nap roller. All new concrete must be cured for at least 30 days prior to application.
In response to public health concerns regarding the carcinogenicity of PAHs some municipalities, such as the city of Milwuakee, have banned the use of common coal tar-based road and driveway sealants citing concerns of elevated PAH content in groundwater.

The cold applied coal tar coating systems include cold applied coal tar paint, cold applied tasteless and odorless coal tar paint, coal tar epoxy, coal tar urethane, and coal tar emulsion. Hot applied coal tar enamel is widely used to protect the inter- ior and exterior of buried water mains and the interiors of water storage tanks.
It is now banned in the developed nations like US, Europe, Japan, etc. As the use of coal tar is being restricted, there is an urgent need to formulate a coal tar free epoxy product for corrosion protection of structures.
f Coal Tar Pitch is a FLAMMABLE LIQUID and a DANGEROUS FIRE HAZARD. f Coal Tar Pitch volatiles are chemical mixtures. For more information, consult the Right to Know Hazardous Substance Fact Sheets on BENZO(a)- PYRENE, CREOSOTE, CHRYSENE, and ANTHRACENE. Workplace Exposure Limits The following exposure limits are for Coal Tar Pitch volatiles:
Coal-tar sealants, which are often used to blacktop parking lots, driveways and playgrounds, would be banned in the city under a proposal being considered by the Milwaukee Common Council.
For epoxy systems such as coal-tar epoxy, polyamide epoxy, and amine epoxy, coats of 300 to 400 micron thickness are generally used. For waterline and submerged zones of structures, the antifouling biocide layer is applied on offshore structures as well, after the epoxy layers are dried.
Within the state of Texas, the Edwards Aquifer Authority has adopted a ban of coal tar sealants over environmentally sensitive portions of Hays and Comal counties, the city noted. Austin banned the use and sale of coal tar sealants in 2005, and San Marcos unanimously approved a ban in May.
Coal tar sealers main ingredient is just that, coal tar. Coal tar is a thick, black liquid that is a byproduct of the distillation of bituminous coal (usually in the electricity production industry). Coal tar is mixed with additional minerals dependent upon the manufacturer. For decades, coal tar has been the king of sealcoating.
Coal tar enamel was regulated out of use in the 1970's. Since then, epoxies, which are more expensive to purchase and apply, have been used as a replacement. The epoxy service lifetime is approximately to 20-30 years. This maintenance cycle for protecting aging infrastructure is not practical, nor is it affordable to Reclamation facilities.
Blue Water Marine Coal Tar Epoxy Primer is a heavy-duty, high-build protective coating with a blend of epoxy resin and coal tar that provides excellent protective barrier coating on steel, iron, and concrete. The tar additive boosts flex and elongation, and is excellent at sealing out moisture.
The coal tar is in the form of a semi-liquid pitch and blended with the epoxy resin. The curing agents for coal tar epoxies are usually either amines or polyamides. Coal tar epoxies offer excellent resistance to fresh and salt water and are highly resistant to cathodic disbondment.
On March 8, 2012 HR. 4166 - Coal Tar Sealants Reduction Act of 2012 was introduced in congress to prohibit the manufacture, processing, distribution in commerce, and use of coal tar sealants and to provide a nationwide ban on coal tar pavement sealant use by 2015.
Coal-Tar N is a bituminous, two-component polyamide-epoxy. It can be applied in one-coat application of 18 mils with no loss of ad hesion. It displays excellent weathering and resistance to salt an d fresh water degradation for steel and concrete.
Coal tar enamel (CTE) is a polymer-based coating produced from the plasticization of coal tar pitch, coal, and distillates. Inert fillers are added to provide the desired properties of the system. The coal tar pitch, which forms the basis for the enamel, consists of polynuclear aromatic hydrocarbons and heterocyclic compounds.
Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coal-tar products, such as creosote and coal-tar pitch. Certain preparations of coal tar have , coal tar epoxy banned
