Haz, just because other people are not supporting you it doesn't mean you should reply in a non professional way. The best approach is to let your product do the talking. By this I mean you have extensively tested your resin against others and, in your tests yours is better? I don't have a problem with that as a statement but the way to get people on board is to prove you are right.
Maybe post what tests you have carried out and what the results were i.e. you tds going in, tds, out flow rate, pressure, volume of resin vessel, and show the tds output curves vs volume.
The bottom line is everyone who uses resin wants the cheapest resin cost per 1000 litres that gives them 0 tds. If you can show that yours is cheaper using data and keep your interactions professional no matter what you think of others replies then I am sure you will make a fortune.
