dissolve method
put all the solvents in the reactor, and while stirring, put the pt-17 solid reactor: after adding all components, raise the reaction temperature to 90~100 degrees. if mek and acetone are used, raise the reactor temperature to 50-60 degrees and stir for two hours. maximum pressure of the reactor: 2kg/cm 2, turn off the heating system, continue stirring for one and a half hours, let the reactor cool n naturally, stop stirring; filter the solution and put it into a 200kg barrel
applicable solvent : ek, toluene, xylene, solvesso, cyclohexanone, acid gas cellulose ester, isophorone, dbe
original recipe : prevent back-adhesive screen printing adhesive
