a) Teflon, silicone, wax and polypropylene all reject PURETi’s water based carrier and are the only four materials to which PURETi will not bond.
b) Wax applied over PURETi will block the moisture needed to activate photocatalysis.
c) PURETi may degrade certain organic substrates, such as latex paint or soft plastic, then fall off the material being treated. In these cases, a first coat of non-photoactive PURETi primer (called Base) can applied that will not damage the organic material, followed by a second coat of photoactive PURETi that will do the job. In a production process where the cure process is being accelerated from 24 hours down to only seconds, the first coat can be followed immediately by the second.
