Recommendation for Resin Dissolving Procedure:
Begin by agitating a weak solvent, such as ethyl acetate or toluene, in the blending tank.
With agitation, slowly add terpolymer resins such as UMCH or UMOH to the above solvents.
Strong solvents, such as MEK or MIPK, should be added last.
If possible, keep the temperature at 60-70 degrees Celsius to aid the dissolving process; otherwise, it will take longer.
The concentration of resin may vary depending on the client’s formulation.
Resin concentration may vary with client’s formulation
Features:
This terpolymer contains a carboxyl group, so it has good adhesion to aluminum foil. It also has good resistance to alkali, base, brine, salty mist, and oil ester and alcohols because it contains PVC.
Packing and Storage:
25 Kg /Bag; Craft Paper Bag or PP Knitted Bag lined with plastic film.
Store in a dry place at room temperature. For safety concerns, consult MSDS and SGS reports.
