Veggie-Plastic Coating Ecodur Showing Potential to Protect Hundreds of Millions of Wood Rail Ties, Following Tests

Reno, Nevada, January 30, 2017 – An all-weather test trial of wood railway ties with an Ecodur veggie-plastic coating has shown no degradation and excellent penetration through the original creosote protective layer, bringing the prospect of radically prolonging tie life and reducing toxic run-off.

US railroads have 200,000 miles of tracks and on the majority of the ties are creosote-treated wood laid at the rate of 3,249 per mile.

“There are between 700 million and 800 million crossties in the US alone and about 90% are chemically treated wood ones. Each year nearly 19 million are replaced,” said Castagra CEO, Peter Roosen.

“Our testing, in fully exposed all-weather conditions, has shown extraordinary penetration of Ecodur and sealing. Ecodur, which is made of non-toxic vegetable oil and naturally occurring gypsum, forms a flexible, tough barrier that still allows water vapor to escape.”

Roosen explained that commonly used creosote, copper-borate and copper naphthenate-borate tend to leach out into the environment causing concerns. In Europe, creosote for tie use has been banned but millions of wood ties still exist impregnated with it.

Chemically treated wood ties have a potential life of up 50 years but seldom last that long due to weather conditions. They are also substantially cheaper than pre-stressed concrete and composite ones.

Coal-tar creosote is still the most widely used wood treatment today and its use on a commercial scale began in 1838. Its dominance is eroding as concerns mount about its carcinogenic potential, especially in the EU which sharply restricted its use from June, 2003.

“Wood creosote occurs commonly in nature, especially where there are forest fires. What we can do potentially is provide a cheap, non-toxic green coating product to keep the creosote safely contained inside the ties, while protecting them from the degrading effects of rain, snow, ice and sunshine which heats them up and attacks them with UV,” observed Roosen.

“We base our optimism not only these recent trials but also the 20-year ones involving Ecodur shavings in brine which have shown absolutely no measurable degradation. We knew Ecodur performs well on wood as it bonds at the molecular level with cellulosic materials.

“It has shown stunning performance against a wide variety of chemicals encountered in the fracking industry too so there’s every reason to believe it will greatly extend he working life of rail ties which have the weather to contend with,” concluded Roosen.

Ecodur has no VOCs, no BPA, is non-toxic, sprayable, foamable, and meets the tough potable water contact regulation NSF/ANSI-61, making it ideal in sensitive water sheds and adjacent to streams and rivers.

Castagra Products Inc., which has its headquarters in Reno, Nevada, has its main toll production facility in Houston in Texas. It is focused on providing ultra-protective non-toxic coatings for flooring, roofing, water and waste water industries, oil, gas, frac production water storage tanks and pipes.
