Dow is a "CYA" company in most of it's statements. I have a aquaponic farm and we use blueboard as rafts for our plants. If you were to contact DOW, and tell them what you are doing with the blueboard they will end any conversation with you. It doesn't surprise me DOW has taken this stance, any supplier could legally responsible should anything be taken to the courts.
Exactly .. as a business owner myself, I'll state ..
Any company, especially those the size of DOW, even get a hint that there could or might be a liability of any sort thru the use of any product, they are going to insulate themselves legally as much as possible .. this is not isolated to the PV market, it's any market ..
And, the Company is, whether we like it or not, doing the right thing for the Company, in the Opinion of the Company .. DOW Management and Board answers to stockholders ..
And, when any Customer starts buying 55 gallon drums of anything, there is a qualification process and DOW has the right to sell or not sell to who they please ..
The fear mongering, woe is me, fanning the flames hoopla that seems to always permeate these type threads is just the usual ECF noise, in most cases made by the same noise makers .. bottom line .. ?? PG / VG is not going away ..
