You can see the effects of additives on BYK YouTube. Observation of wetting on base leather with Big Chemie silicone surface treatment agent. Poor wetting on leather containing mineral oil. Improved wetting tendency on the base with the addition of wetting agents. Two types of water-based blue paint were applied to leather containing a small amount of mineral oil. The paint without additives (left) does not wet. The paint with a polysiloxane-based additive that lowers surface tension (right) shows good wetting on the base.
