Protective Coatings: The Way Forward, Naturally.


Phoenix, AZ. “We see a clear path to pushing the green product boundaries even further. We already have the greenest protective coatings commercially available with performance considerably superior to most conventional ones,” said Castagra Products, Inc. CEO, Peter Roosen.

“But, we are not standing still. The bioplastics industry is expanding rapidly with a wide variety of applications now from automotive to furniture to building products. Castagra is exploring how natural fibers which, demonstrably in research projects, have shown how they can boost performance and reduce costs.”

The global market for bioplastics is predicted to grow by roughly 25 percent over the next five years. Research and Markets, a consultancy, has predicted that the global market for bio-plastics will be worth $43 billion by 2022. Another market research study released in March 2019, concluded the global bioplastics market is set for rapid growth, reaching USD 35.47 billion also by 2022.

“The market numbers are huge and reflect the enormous synergy there is for replacing fossil fuel based plastics. The bottom line is bio-plastics have to perform as well as conventional ones, but also often have to have the ability to biodegrade safely and relatively quickly. We all know about biodegradable plastic bags at supermarkets and the ones used by dog owners.

“Conventional plastics can take hundreds of year to disintegrate in landfills. Hundreds of thousands of tons of waste plastics end up in oceans annually where many break up into micro-fragments which get ingested causing gender changes in fish and crustacea because softening chemicals in the plastics have pseudo oestrogenic effects. Much landfill plastics will still be there in a thousand years, or more because the long chain molecules are so resilient,” continued Roosen.

Plastic has been found in more than 60% of all seabirds and in 100% of sea turtles species, that mistake plastic for food, according to Ocean Conservancy. The organization says eight million metric tons of plastics enter our oceans annually on top of the estimated 150 million metric tons that currently circulate in marine environments.

“We first produced our VOC-free, non-toxic bio-plastic 25 years ago. Then, we were making flexible baseboard moldings, coatings and were experimenting with other solids such as shingles. We have been very successful in floor, roof, and oil and production water tank coatings. Now we are re-visiting our vision of bio-plastics.

“Considerable research on fiber reinforced polymers has clearly demonstrated that the addition of natural fibers can improve performance very significantly while reducing costs as the fibers have largely been a waste product.

“Uniquely and very importantly, Ecodur bonds molecularly with cellulosic materials with prime examples being wood, straw, hemp, and kenaf. This ability was exploited years ago with elongated wood strands incorporated with our veggie-plastic formula into beams for buildings. The beams showed an immense increase in strength and stability.

“Since the signing of the US Farm Bill on December 20, 2018, there has been an enormous boost for cannabis and hemp production. This will inevitably result in a rapid increase in fiber production. Hemp bast is one of the very best candidates for reinforcing polymers. Given our use of renewable castor oil as the main ingredient in Ecodur and its ability to molecularly bond with cellulosic material, it makes hemp a top candidate for use to move forward in bio-plastics,” concluded Roosen.

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 roofing, floors, water and waste water industries and oil, gas, frac production water storage tanks and pipes.
