Re: Wolfgang Exterior Trim Sealant Petroleum & Silicate free? Water Based?
What you mean is silicones not silicates. Silicates are the minerals that form rocks like quartz. Silicones contain silica, oxygen, and carbon, and are a polymer. WG ETS is a polymer based product, yet, I don't know exactly how they derive the polymer in it/from what elements. Either way I don't believe it is the oily type of silicone like found in Armorall since it dries and doesn't leave a sticky/oily film that collects dirt. As far as it containing a petroleum product as its carrier and/or catalyst, I am ignorant to what other types of chemicals/liquids, not derived from petroleum, can be used for that purpose to say one way or the other. To know for sure we would have to hear from the chemist that mixed the formula for WG ETS. From my experience with using WGETS on black plastic and rubber I have not seen any ill effects that come from the products you are trying to avoid. I know that on the cap of my WGETS the residue dries to an opaque green, gummy substance, which IMO is not how a plasticizer leaching product would dry, if it would "dry" at all. Silicones are used in cosmetic/health care products and are a low-toxicity, so that means that they can be made to be safe for plastics as well.
