Ecodur 201 Protective Coatings

Castagra is a leader in the green coatings industry with over 20 years of performance and protection in some of the toughest industrial environments where extremes are the norm.

The base product Ecodur is a plasticized gypsum formulation that combines the best attributes afforded by a vegetable oil and a commonly occurring rock mineral – retained flexibility, durability and chemical neutrality.

It is free of Volatile Organic Compounds, BPA-free, rated for use in contact with potable water (NSF-61/AWWA D102), can be re-applied to itself for the life of the coating, and very significantly, it does not contain solvents, or require them in application or clean-up.

Today, Ecodur has been applied to well over a thousand oil tanks in the oil and gas industry, to numerous drinking water and waste water facilities, as well as in major food manufacturing and handling facilities.

Our coatings can be readily applied to vertical surfaces with the patented spray technology allowing for maximum ‘sprayability’ in confined spaces where manual application would be most difficult if not hazardous.

Further adding to Ecodur’s overall performance characteristics is the fact that it can be applied in such extreme winter environments as those experienced in North Dakota for example.

With its life-long ability to bond back on any repair, clients can have the confidence that any remedial work can be confined to the target area rather than requiring the entire stripping of a coating as often happens with conventional epoxy coatings.

With many companies opting to sourcing ‘green products’ it is notable that being comprised principally of castor oil, which is renewable, and gypsum which is recyclable, this biologically inert material achieves the highest level of protection for the environment both during its lifetime and when disposed.

Now, Ecodur’s benefits are extending into foam applications. With the same basic qualities of Ecodur, the foamable product is extending into wider potential applications as it has excellent insulating qualities and retains its high fire retardant rating.

Key Benefits Include:

Cold weather application Major E&P company, North Dakota Tank)
Lower cost
Higher durability
Faster application speed (increased throughput)
Decrease or eliminate downtime
Increased safety (Flashpoint comparison)
Non toxic (VOC-free and BPA-free)
Infinitely repairable because they ‘autobond’ to previous coats (Ecodur Manual Tank Coating and Touch Up Kits)

Typical applications include:

• Industrial Flooring (Kern)
• Tank OEMs: Coating new oil storage tanks and frac tanks (Apache, Paint booth bottleneck, Facility Expansion, Steel Tank Fabricator, Baker Tank).
• Refurbishing old oil storage tanks and frac tanks. (EOG Resources, Legacy Tank, Encana/Cameron, Pemex)
Reservoir coatings
• Secondary Containment (XTO, tank farm).
• Ship deck coatings
• Railcar coatings
• Riveted tank coating and lining
Structural rehabilitation for water and wastewater.
• Certification NSF-61 for water tanks (Pittsburg Tank).
• Pond linings.

Case Study #1

At a remote northern Montana location, an American pipeline company required a suitable crude oil tank lining that could be installed and cured quickly at freezing temperatures to minimize operational downtime, while providing long service life for high sulphur “sour” crude oil. Download Case

Case Study #2

Colorado oilfields employ many steel tanks that have been in service for several decades. It turns out that some of these oilfields are outlasting these tanks used to collect the oil. A mid sized independent oil/gas company has found Castagra’s Ecodur 201 protective coating to provide a cost-effective solution to refurbishing old bolted tanks that were assembled and installed many years ago to collect 170 degree F hot oil. This provides oilfield operators a much lower cost alternative to replacing aging tanks. Download Case

“The blending process has no waste stream. 100% of the ingredients introduced into the blend leave the process as finished liquid products or as input materials into the next stage of production which has solid goods as output.”
