[Greenbuilding] Rustoleum NeverWet?

[John Salmen]

This could be part of a bigger conversation about nano fabric coatings (nano – everything coatings). It becomes less about the chemicals used (silicone or PU or vinyl) than about particle sizes of the chemicals. Is a silicone based waterproofing material more or less toxic than the conventional polyurethanes used with gortex type coatings? The answers change when the particle size changes and that is the concern with nanotechnology. Silicone is less toxic than urethanes in terms of chemical composition but at a nano level both are identified as producing inflammatory reactions related to cancer production.  How stable are nano particles when utilized in coatings? Silica nano particles are used extensively in cosmetics

Subject: [Greenbuilding] Rustoleum NeverWet?

 

This product was brought up in a backpacking forum I reside on.

 

I know I have my personal skepticism, but I thought I'd seek some council from a circle of peers whom I deeply respect for their collective wisdom.

 

Does anyone have any thoughts or opinions about this stuff? I just feel a moral obligation to see what professionals think of this, before I witness a bunch of backpackers spraying all their equipment with it, and walking off into the ecosystem oblivious to the greater impact.

(I understand they are planning on coming out with a transparent color.)

 

In Gratitude,

 

Matt
