You can see the effects of additives on BYK YouTube. Explanation of blocking and blocking prevention of air-drying paint. Paint air-drying paint on paper. After drying, hold the painted paper with the painted side facing inward. Place a weight on top so that the painted surfaces touch each other. Then remove the weight and peel the papers apart. Due to the paint formulation, the painted surfaces stick together, causing damage when peeled apart (blocking). This can be avoided with blocking prevention additives.
