| Rosin ester dispersion |
 |
XR-4257 is a unique high-solids dispersion of a rosin-based tackifier, especially
formulated for pressure sensitive adhesive (PSA) applications.
XR-4257 is compatible with the dominant PSA polymers including acrylics and CSBRs.
Compared to AQUATAC 6085, most adhesives formulated with XR-4257 will have more aggressive
tack and peel, with minimal loss in shear properties, even after aging. |
