Leveling agents are also fluorocarbon and high boiling solvents.

Aug 7, 2017

Leveling agents are also fluorocarbon and high boiling solvents. Fluorocarbon leveling agent has the highest surface activity, the coating surface tension can be reduced to 16-18mN / m, so the strongest surface state control. In summary, the silicone leveling agent has the function, fluorocarbon leveling agent all have better than the silicone leveling agent to reduce the surface tension better, the surface state control effect is even better. But also has its negative effects, such as interlayer adhesion, foam stability is more difficult to overcome. Its price is particularly expensive, affecting its application.
Solvent leveling agent is a mixture of high boiling solvents, the main mechanism is to slow down the solvent evaporation rate, reduce paint viscosity, improve leveling agent. But its environmental protection, anti-sagging control, quick-drying requirements are contrary to, so people do not use much.
