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
Features:
This terpolymer contains carboxyl group, therefore, it features good adhesions to aluminum foil, also because it contains PVC so, also has good resistance to alkali, base, brine, salty mist, also has good resistance to oil ester and alcohols.
Packing and Storage:
25 Kg /Bag; Craft Paper Bag or PP Knitted Bag lined with plastic film.
Stored in dry place at room temperature, Safety Issue refer MSDS and SGS Repor
