leveling agent
The fluorine-modified acrylic leveling agent has certain substrate wetting and anti-shrinkage crater properties, while the alkyl-modified acrylic leveling agent increases its defoaming ability. Modification by adding epoxy group, base or antelope group can participate in the crosslinking reaction of the paint film, while polyether modification can adjust the compatibility with the system.

Product description
It can be seen from the flow equation that the surface tension that really drives the flow of the paint film, the higher the surface tension, the stronger the leveling power, the surface tension of acrylic leveling agents is higher than that of polysiloxanes, in high viscosity systems Better performance (increased mobility).
The alkyl ester of acrylic acid acts to provide basic surface activity;
- Applicable to different systems by adjusting polar groups such as antelope and release groups
- The relative molecular mass is directly related to the final spreading performance
- Limited compatibility is a necessary condition for acrylic leveling agents:
- Generally, acrylic acid leveling agents have certain anti-foaming and defoaming functions.
The fluorine-modified acrylic leveling agent has certain substrate wetting and anti-shrinkage crater properties, while the alkyl-modified acrylic leveling agent increases its defoaming ability. Modification by adding epoxy group, base or antelope group can participate in the crosslinking reaction of the paint film, while polyether modification can adjust the compatibility with the system.
