Regaining Old-Time Coating Performance with ‘Natural Skin’ Ecodur


Phoenix, AZ. “We have one of only handful of coatings in the world that lasts as long as paints did over a 100 years ago. In the headlong rush to remove Volatile Organic Compounds, for instance, there has been a loss in durability and a global rash of coating failures.

“One major factor has been the huge move into water-based acrylics which simply don’t allow water vapor to exit quickly enough especially from substrates such as wood which can quickly rot if there is also an internal vapor barrier behind it.

“Ecodur is totally waterproof, but permits vapor molecules to pass through which is very important where wood is concerned. Furthermore, it actually binds molecularly with cellulosic materials making the ultimate bond like a natural skin.”

Roosen explained that Ecodur is made from renewable castor oil and naturally occurring gypsum and has zero VOCs, BPA and solvents. It is completely non-toxic, highly flame retardant retains its flexibility for its lifetime, and, very importantly, can be repaired at any time during its lifetime too as the original surface re-bonds to new coats.

“The modern era of paint follows from the end of the Second World War. The demand grew for cheaper, quick drying rates, and as big a variety of colors as possible, followed by the lead scandal and the greening movement and its hard drive against VOCs and solvents.

“Boiled linseed oil gave way to alkyd oils and now you have all the acrylic water based paints which have their own set of health-related concerns. The irony is the boiled linseed oil paints of a hundred years ago lasted far longer than the vast majority of modern coatings save ours which is also oil based,” stated Roosen.

“I know of fridges and vacuum cleaners manufactured shortly after the war that comfortably lasted 30 or 40 years. Built in redundancy is a fact of life. In the coatings world, few manufacturers have managed to match old time performance with the public’s and end users’ demand for safety, zero toxicity, performance and price competitiveness,” he commented.

“For a quarter of a century our plasticized gypsum has been applied to many hundreds of oil and production water tanks, flooring, roofs, concrete and streel structures, including water and waste water facilities. It is even approved for contact with drinking water and can be used in food storage areas.

“In effect, we have been proven out in the harshest industrial environments including exposure to not only extremes of temperature and UV, but also the cocktail of chemicals that get used in the fracking industry.”

Ecodur has an additional standout feature largely due to its gypsum content. When Ecodur is exposed to flames, its trapped water molecules emerge as water vapor, often to the point where it will extinguish small flames. It has a Class A flame retardant rating.

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.
