Stepan Company Finds Improved Blocking Resistance with STEPCOTE™ W-877

Tech Paper | Supplied by Stepan

Stepan developed a new line of multifunctional wetting agents. STEPCOTE™ W-877 can efficiently lower surface tension of a water-borne paint while improving the high temperature block resistance.

Did you know that the speed at which the additive moves to the air/film interface is critical to its blocking performance? In this study, structure-function relationships were explored against critical variables like speed to the interface and efficacy of surface energy reduction. Understanding the why is important.
Have questions? Stepan would be delighted to talk chemistry with you.
