PolyWheyâ„¢ Floor and Furniture Coatings From Vermont
Got a dairy that makes cheese? If you do, you've also got whey which you likely pay to manage as a waste - unless you are a whey supplier of Vermont Natural Coatings, that is.
Vermont Natural has developed two whey-based coatings: one for wooden furniture; and, the other for floors. The results look good on their web site. Odor is reported to be less than for comparable synthetic coatings, such as urethane or epoxy; and, remarkably, odor is described as less than even other water based-coatings.At first glance, the price, in excess of US$60/gallon, seemed high. Then we saw these two specs, which explain the value:
Conventional water-based finishes have an average coating coverage of 300 to 400sq.ft./gallon PolyWhey’s cover is 450 to 500sq.ft./gallonWe have no idea how good these whey-based coatings perform for chemical resistance and UV stability. However, the Vermont Natural Coatings website explains that "Some conventional oil and water-based finishes contain toxic heavy metals and formaldehyde. PolyWhey’s™ binder is non-toxic whey protein."
PolyWhey has a cured hardness twice that of other water-based finishes which means it is hard wearing even on floors that have heavy traffic.
Per the product MSDS listed by Vermont Natural, two of the curing components of these coatings pose a potential health hazard while in liquid form (before curing). So, as with any paint, or stain, you want to minimize skin contact and inhalation of aerosols.
