Syneffex has MANY DOCUMENTED ASTM tests on their website (if you ever looked)
12 different tests for thermal performance, resistance to corrossion, mold, etc (many are ASTM) !!!!!!!!!! The referenced tests below have been performed by Accredited Third Party Laboratories. https://www.syneffex.com/synavax-independent-testing-data/
So great that you now know that you have been wrong all these years about INTK not having the tests donel.
I guess now you will become a big buyer of INTK stock. Welcome aboard!!! LMAO
