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 down 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
