Hello, I am currently working on laying down the deck on my boat. Bigger project than I thought.... I am working with vinyl ester resin and MEKP as a hardener. I am using a half mask and bottom of the line safety goggles since MEKP in the eyes causes blindness!
The half mask has Honeywell 7581p100 filters and these seems to work as I do not smell product at all. But I still think I notice the effects through my eyes or maybe the filters aren't working for these chemicals. So I called Honeywell Safety Products and they said that they don't offer a mask that works with Vinyl Ester resin, or that they simply don't list that chemical with a recommended filter.
So I asked about the MEKP (Methyl Ethyl Ketone Peroxide) and they said no mask is necessary below .2 ppm (parts per million) and from .2 to 200 ppm requires a mask with an outside air supply! They don't have a filter that will work! They also said that they can't make a recommendation anyways because I don't know the concentrations of chemicals that I am working with. How could I figure that out anyways?! The amount of product used to the "out gassing" it gives off is an unknown to me.
So I guess this will be the last time I work with Vinyl Ester resins? Am I harming myself by using this product?
As a side note, I went to a fiberglass repair shop for a few last minute yards of fiberglass cloth and the workers there were working with either vinyl ester or polyester resins without any protection at all, eye or air!
Side note two, this stuff does stink! My shop is well ventilated and everyone can still smell it at the street +-110 feet away from the doors. Poor neighbors.
Thoughts?
