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.
