basic information
【BYK-3105】Mechanism of Action: • Bubbles coalesce to form larger bubbles. • Larger bubbles have higher buoyancy, leading to faster defoaming and bursting at the surface. 【BYK-3140】Mechanism of Action: • Bubbles coalesce to form larger bubbles. • Larger bubbles have higher buoyancy, leading to faster defoaming and bursting at the surface. 【BYK-3155】Application: • High volatility → Suitable for low fogging applications. • OH group → Highly reactive and prone to cross-linking reactions (such as isocyanates). 【BYK-1160 Family】Mechanism of Action: • Yield point decreases, exhibiting a thinning effect at low shear, improving the buoyancy of bubbles.
