FAQ
The CMC of Gemini 12-2-12 is approximately 100 times lower than conventional single-chain surfactants like DTAB. This means full wetting and dispersion activity is achieved at 0.01–0.05% dosage, dramatically reducing the risk of foam, water sensitivity, and film defects associated with excess surfactant. It is particularly useful in pigment concentrates where minimizing surfactant load improves film mechanical properties.
