Ecodur 201: Coating Applicator Safety (VOC-free)


Over 100,000 new compounds have been used in common consumer products in recent decades coinciding with world asthma and lung disease rates continuing to rise. Medical studies have shown how many people are sensitive to epoxy resin and adhesive fumes. In one study workers were shown to be variously sensitive to triethylene tetramine fumes, acid anhydrides, phthalic acid anhydride and trimellitic anhydride.

Most countries report population rates of allergic diseases, including asthma, of between 15%-35%, with the worldwide average being 22%. Asthma rates have been growing since the early 1980s and by 2004, 1 in 15 Americans were suffering from asthma.

One study in Sweden showed children, who sleep in bedrooms containing fumes from water-based paints and solvents, are two to four times more likely to suffer allergies or asthma. The culprit chemicals, propylene glycol and glycol ethers, known as PGEs, were in the bedroom air of 400 very young children. The study found that the children, who had breathed PGEs, had substantially higher rates of asthma, stuffy noses and eczema.

PGEs are common in water-based paints and varnishes. A number of PGEs are known endocrine disruptors, very little is known whether and how they influence developing immune systems, said the study.

This case study concerns one of Castagra’s applicators who has a very strong dermal reaction to exposure to fumes emanating from conventional epoxy coatings, despite a number of them claiming to be zero VOC.


How to avoid exposure to chemicals that may not appear to have any detrimental effects on the majority of people, but you are one of those who have become sensitized to the point where close proximity causes a moderate to severe allergic reaction from chemicals off-gassed by epoxy resins.


This case study’s individual having worked professionally with conventional epoxy coatings and experienced detrimental effects, was introduced to Castagra’s Ecodur bio-renewable coating. He devised personal exposure tests to make sure Ecodur did not trigger any reactions. Formerly, he had broken out in hives when working with certain conventional epoxy coatings which severely limited his ability to expand his business opportunities.

Ecodur, which is made from castor oil and naturally occurring soft rock gypsum, has zero VOCs, zero Bisphenol-A (BPA) and phthalates. It is non-toxic, and, importantly, certified for use in contact with drinking water.

Application Results

Ecodur’s formulation history goes back nearly 25 years. From the safety point of view, it has to meet the same standards as any other epoxy protective coating as it could potentially cause during its reactive phase, severe damage to unprotected eyes, airways and lungs if breathed in. It, typically, has double the adhesion of conventional epoxies so the safety instructions must be followed completely.

The case study subject is now able to safely work with a coating that provides him with a safe and natural alternative without any sacrifice in performance compared to conventional epoxy coatings.
