Technical Data Sheet Sample Request MSDS Request
Technical Data Sheet  Request a Sample Technical Data Sheet 

  DISPARLON 4401-25M is a paste of polyolefin wax swollen/dispersed in mineral spirits. This product has a high flash point of more than 40 ℃, and a lower content of aromatics than DISPARLON 4200-20.
4401-25M acts not only as an anti-settling/sagging agent but also as a stabilizer for pigment dispersion, contributing to a longer shelf life of solvent based enamels.



ADVANTAGES:
Prevents pigment settling and hard caking on aging without affecting viscosity.
A high flash point because the solvent used is mineral spirits.
Lower contents of aromatics than pastes using xylene.
Stabilized pigment dispersion prolongs shelf life.
Controls sagging of some enamels.
Non-seeding and little affect on film gloss and leveling.
