Recommendation for Resin Dissolving Procedure:
Add weak solvent such as ethyl acetate or toluene into the blending tank first with agitation.
Slowly put terpolymer resin such as UMCH or UMOH into the above solvents with agitation.
Put strong solvents last, such as MEK or MIPK
If possible, heating and keeping temperature at 60-70 degree C, which will help the dissolving process, otherwise, takes longer time.
Resin concentration may vary with client's formulation
