PINECRYSTAL® KE-604

PINECRYSTAL® KE-604 is a colorless, hydrogenated rosin adduct from Arakawa Chemical. KE-604 provides excellent long term stability in formulations requiring a clear and water-white appearance.


Product Code: PC-1002

Product Name

PINECRYSTAL® KE-604

Applications

PINECRYSTAL® KE-604 can be used in a wide variety of formulations where both high acid number (carboxyl functionality) and high softening point are desired for optimal performance in adhesive applications including double-sided PSAs for electronic and automotive products, hot melts, soldering fluxes and specialty printing (dyes/pigments).

Specialty applications for PINECRYSTAL® KE-604 include soldering flux where the high acid number promotes adhesion and surface cleaning.

Benefits

A key benefit of the PINECRYSTAL® KE-604 is its unique combination of high acid number functionality and softening point, excellent solubility in polar solvents, alcohol solubility and water white appearance. In addition, the high acid number provides additional functionality for post curing reaction mechanisms.

Storage and Inventory Control

Resins may fuse, block, or lump during hot weather months, if stored near sources of heat, double or triple stacked, or stored for prolonged periods of time. These forms of resin are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents. Care should be given to minimize opportunities for product oxidation throughout processing. Accordingly, it is strongly recommended that proper storage conditions and strict control of inventory be observed at all times, taking care that the oldest material is used first.
