Veggie-Plastic for the Natural Marriage of Wood and Protection


PHOENIX, AZ. “After a quarter of a century protecting innumerable concrete and steel structures, our attention has been turning more and more to the vast amount of timber products that need protection against the elements,” said Castagra Products, Inc. CEO, Peter Roosen.

“In North America alone, there are a billion wood railway ties and 160-180 million wood utility poles out there in various stages of decay because the traditional but toxic creosote coating has been outlawed.

“Wood is a marvellously versatile material but when nature gets to work blasting it with UV, hot winds, freeze and thaw, rain and bugs, it can deteriorate rapidly. You only have to drive around the countryside to see what it does to untreated sheds and barns.”

Roosen said the company’s product Ecodur which is made from vegetable oil and naturally occurring soft rock gypsum, is the greenest coating available but also the toughest and longest lasting.

“It bonds molecularly with wood because of its unique chemistry. There is no tougher bond than one that occurs at the molecular level, so Ecodur is absolutely perfect for wood. Combine this with its very high UV and flame resistance, and the fact that it is certified for use in contact with drinking water and completely non-toxic, we see it having significant potential for flooring protection in animal housing where hygiene is of paramount consideration,” observed Roosen.

“Over time many diseases have become more resistant to treatments and thus many have become tougher on conventional coatings. It is vital too that coatings withstand physical contact with cleaning and disinfecting machines and products as well withstanding the general rigor associated with housing livestock.”

Roosen pointed out that Ecodur is deck coating on heavily used ship decks and 20-year-plus brine submersion tests have shown no measurable degradation.

“Whether coatings are to protect humans or animals, it is very much about the purity of the coating right at the get go. If you start with a zero VOC, zero BPA, zero toxic content product such as ours, there is simply no possibility of its adding any harmful as do many coatings still in widespread use today such as asphalt, PVC and synthetic rubber compounds.”

Roosen said his most recent breakthrough has been with wood railroad ties and utility poles heavily impregnated with creosote, which, unless cocooned in a protective coating can and does leach into the surrounding soil.

“Our results have been outstanding in terms of Ecodur driving into the wood through the creosote and form a tough plasticised gypsum seal that will last for decades with the treated wood safely encapsulated. This would work very well for making safe asbestos which is still found in many schools and can be sealed in this way in compliance with EPA regulations.”

Castagra Products Inc., has its registered office in Reno, Nevada, USA, and headquarters in Phoenix, Arizona. It has its main toll production facility in Houston in Texas. The company is focussed on providing ultra-protective VOC-free, BPA-free, non-toxic coatings for flooring, roofing, water and waste water industries and oil, gas, frac production water storage tanks and pipes.
